Prison Management System in java

An application is to be developed that manages the wardens and prisoners at a prison. Each prisoner is identified by a unique number. Details, such as name and number of days left to serve in prison, need to be stored for each prisoner as well as the unique identifier. Some prisoners are categorized as high security prisoners, in which case additional information must be stored, such as security level and whether or not the prisoner can share a cell with another prisoner. Wardens have a rank in the range 1 to 5, where a rank of 5 indicates the highest level of experience.
The application must provide at least the following functionalities:
- Add a new prisoner
- Find and display a prisoner, identified by number
- Release a prisoner, identified by number (a prisoner can only be released, at the discretion of the prison services, if they have less than 7 days left to serve)
- Delete a prisoner (this function will come into play in the event of death of a prisoner)
- Add a new prison warden
- Delete a prison warden
- Display all the wardens
- Display all the prisoners

QUESTION 19

What is difference between StringBuffer and StringBuilder in Java ?
Solution :
Classic Java questions which some people thing tricky and some consider very easy. StringBuilder in Java is introduced in Java 5 and only difference between both of them is that Stringbuffer methods are synchronized while StringBuilder is non synchronized. See StringBuilder vs StringBuffer for more differences

QUESTION 18

What is the difference between creating String as new() and literal?
Solution :
When we create string with new() Operator, it’s created in heap and not added into string pool while String created using literal are created in String pool itself which exists in PermGen area of heap.

String s = new String("Test");

does not  put the object in String pool , we need to call String.intern() method which is used to put  them into String pool explicitly. its only when you create String object as String literal e.g. String s = "Test" Java automatically put that into String pool.

QUESTION 17

What is immutable object? Can you write immutable object?
Solution :
Immutable classes are Java classes whose objects can not be modified once created. Any modification in Immutable object result in new object. For example is String is immutable in Java. Mostly Immutable are also final in Java, in order to prevent sub class from overriding methods in Java which can compromise Immutability. You can achieve same functionality by making member as non final but private and not modifying them except in constructor.

File I/O Streams

You can write data to a file instead of the computer screen. You can write certain data to a file while still putting other data on the screen. Or you may need access to multiple files simultaneously. Or you may want to query the user for input rather than accepting it all on the command line. Or maybe you want to read data out of a file that's in a particular format. In Java all these methods take place as streams. < > Using File I/O streams. The System.out.println() statement we've been using all along is an implementation of Streams.

A program that writes a string to a file

In order to use the Java file classes, we must import the Java input/output package (java.io) in the following manner

import  java.io.*;

Inside the main method of our program, we must declare a FileOutputStream object. In this case, we wish to write a string to the file, and so we create a new PrintStream object that takes as its constructor the existing FileOutputStream. Any data we send from PrintStream will now be passed to the FileOutputStream, and ultimately to disk. We then make a call to the println method, passing it a string, and then close the connection.

Source Code

/*
* FileOutput
* Demonstration of FileOutputStream and PrintStream classes
*/

import java.io.*;

class FileOutput 
{ 

public static void main(String args[])
{ 
FileOutputStream out; // declare a file output object
PrintStream p; // declare a print stream object

try
{
// Create a new file output stream connected to "myfile.txt"
out = new FileOutputStream("myfile.txt");

// Connect print stream to the output stream
p = new PrintStream( out );

p.println ("This is written to a file myFile.txt");

p.close();
}
catch (Exception e)
{
System.err.println ("Error writing to the file myFile.txt");
}
}
}

Interactively communicating with the user

Program asking  the user for their name and then prints a personalized greeting.

Source Code

import java.io.*;

class PersonalHello {

  public static void main (String args[])
    {
    
      byte name[] = new byte[100];
      int nr_read = 0;

      System.out.println("Your name Please?");
      try {
        nr_read = System.in.read(name);
        System.out.print("Hello ");
        System.out.write(name,0,nr_read);
      }
      catch (IOException e) {
        System.out.print("I did not get your name.");
      }
      
    }
    
}

In code that does any significant input or output you'll want to begin by importing all the various java.io classes. import.java.io.*; Most of the reading and writing you do in Java will be done with bytes. Here we've started with an array of bytes that will hold the user's name.

First we print a query requesting the user's name. Then we read the user's name using the System.in.read() method. This method takes a byte array as an argument, and places whatever the user types in that byte array. Then, like before, we print "Hello." Finally we print the user's name.

The program doesn't actually see what the user types until he or she types a carriage return. This gives the user the chance to backspace over and delete any mistakes. Once the return key is pressed, everything in the line is placed in the array.

Reading Numbers

Often strings aren't enough. A lot of times you'll want to ask the user for a number as input. All user input comes in as strings so we need to convert the string into a number.

The getNextInteger() method that will accept an integer from the user. Here it is:

  static int getNextInteger() {
  
    String line;
  
    DataInputStream in = new DataInputStream(System.in);
    try {
      line = in.readLine();
      int i = Integer.valueOf(line).intValue();
      return i;
    }
    catch (Exception e) {
      return -1;
    }
       
  } // getNextInteger ends here

Reading Formatted Data

It's often the case that you want to read not just one number but multiple numbers. Sometimes you may need to read text and numbers on the same line. For this purpose Java provides the StreamTokenizer class.

Writing a text file

Sometimes you want to save your output in a  file. To do this we'll need to learn how to write data to a file. 

Source Code

// Write the Fahrenheit to Celsius table in a file

import java.io.*;

class FahrToCelsius  {

  public static void main (String args[]) {

    double fahr, celsius;
    double lower, upper, step;

    lower = 0.0;    // lower limit of temperature table
    upper = 300.0;  // upper limit of temperature table
    step  = 20.0;   // step size

    fahr = lower;
  
    try {

      FileOutputStream fout =  new FileOutputStream("test.out");

      // now to the FileOutputStream into a PrintStream
      PrintStream myOutput = new PrintStream(fout);
  
      while (fahr <= upper) {  // while loop begins here
        celsius = 5.0 * (fahr-32.0) / 9.0;
        myOutput.println(fahr + " " + celsius);
        fahr = fahr + step;
      } // while loop ends here
  
    }  // try ends here
    catch (IOException e) {
      System.out.println("Error: " + e);
      System.exit(1);
    }
  
  } // main ends here

}

There are only three things necessary to write formatted output to a file rather than to the standard output:

1. Open a FileOutputStream using a line like
   FileOutputStream fout =  new FileOutputStream("test.out");
   This line initializes the FileOutputStream with the name of the file you want to write into.
2. Convert the FileOutputStream into a PrintStream using a statement like
   PrintStream myOutput = new PrintStream(fout);
   The PrintStream is passed the FileOutputStream from step 1.
3. Instead of using System.out.println() use myOutput.println(). System.out and myOutput are just different instances of the PrintStream class. To print to a differentPrintStream we keep the syntax the same but change the name of the PrintStream.

Reading a text file

Now that we know how to write a text file, let's try reading one. The following code accepts a series of file names on the command line and then prints those filenames to the standard output in the order they were listed.

// Imitate the Unix cat utility

import java.io.*;

class cat  {

  public static void main (String args[]) {
  
  String thisLine;

  //Loop across the arguments
  for (int i=0; i < args.length; i++) {
 
  //Open the file for reading
  try {
    FileInputStream fin =  new FileInputStream(args[i]);

    // now turn the FileInputStream into a DataInputStream
    try {
      DataInputStream myInput = new DataInputStream(fin);
  
      try {
        while ((thisLine = myInput.readLine()) != null) {  // while loop begins here
          System.out.println(thisLine);
        } // while loop ends here
      }
      catch (Exception e) {
       System.out.println("Error: " + e);
      }
    } // end try
    catch (Exception e) {
      System.out.println("Error: " + e);
    }
  
   } // end try
   catch (Exception e) {
    System.out.println("failed to open file " + args[i]);
    System.out.println("Error: " + e);
  }
  } // for end here
  
  } // main ends here

}
