    System.out.print( "Enter a floating point value:");
    x = keyboard.nextFloat();
    System.out.println(" ch1 = " + ch1);
    System.out.println( "y = " + y);
    System.out.println( "ch2 = " + ch2);

Re-write the above program to use JOptionPane dialog boxes for allinput
and output operations.

Explanation / Answer

publicclass Lab3_Ex1

{

publicstatic voidmain (String [] args)

float x;

String stringY; // this variable will store the int as astring and we convert string to int later.

String strFloat; // this variable will store the float as a string and weconvert string to int later.

int y;

char ch1,ch2;

String name;

String input;

input=JOptionPane.showInputDialog(null, "Enter acharacter: "); // using JOptionpane we are storing theinput

ch1 = input.charAt(0);

stringY=JOptionPane.showInputDialog(null, "Enter a number:");// usingJOptionpane we are storing the input

y=Integer.parseInt(stringY); //here we are converting string to int.

input=JOptionPane.showInputDialog(null, "Enter anothercharacter: ");

ch2 = input.charAt(0);

name=JOptionPane.showInputDialog(null, "Enter a name:");

strFloat=JOptionPane.showInputDialog(null, "Enter a floatingpoint value: ");

JOptionPane.showMessageDialog(null," ch1 =" + ch1,"Character#1",JOptionPane.INFORMATION_MESSAGE);

JOptionPane.showMessageDialog(null, "y =" + y,"Integer#1",JOptionPane.INFORMATION_MESSAGE);

JOptionPane.showMessageDialog(null, "ch2 =" + ch2, "Character#2",JOptionPane.INFORMATION_MESSAGE);

JOptionPane.showMessageDialog(null,"Name is" + name, "Name",JOptionPane.INFORMATION_MESSAGE);

JOptionPane.showMessageDialog(null, "x =" + x, "Floatingnumber",JOptionPane.INFORMATION_MESSAGE);
