package exception;

public class StringTooLongException extends Exception{

public StringTooLongException(){

super("String too long");




 Driver class for StringTooLongException


package exception;

import java.util.Scanner;

public class Driver{

public static void main (String[] args)

throws StringTooLongException{

Scanner scan = new Scanner(;

String enterstr;                            //String to be entered

System.out.print("Enter a string (DONE to exit): ");

enterstr = scan.nextLine();

while (!enterstr.equals("DONE")){

if (enterstr.length()>20)

throw new StringTooLongException();

System.out.print("Enter a string (DONE to exit): ");

enterstr = scan.nextLine();




Q2. Modify the DisplayFile program below to add a button labeled Save above the text area. When the button is pushed, write the contents back out to the file. 

import java.util.Scanner; 


import javax.swing.*;

public class DisplayFile {

   //----------------------------------------------------------------   // 

 Opens a file chooser dialog, reads the selected file and   //  loads it into a text area.  


public static void main (String[] args) throws IOException   {   

   JFrame frame = new JFrame ("Display File");    

  frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

      JTextArea ta = new JTextArea (20, 30);     

 JFileChooser chooser = new JFileChooser();

      int status = chooser.showOpenDialog (null);

      if (status != JFileChooser.APPROVE_OPTION)         

ta.setText ("No File Chosen");     

 else      {         File file = chooser.getSelectedFile();     

           Scanner scan = new Scanner(file);

         String info = "";       

         while (scan.hasNext())           

          info += scan.nextLine() + "\n";

         ta.setText (info);      }

      frame.getContentPane().add (ta);
