Write a java program using Dialog boxes that prompt the user to input five floating point decimal numbers. the program should then add the five numbers, find the average, convert sum and average to the nearest integer, and print the numbers, sum and average. Solution The java program using Dialog boxes that prompt the user to input five floating point decimal numbers :- import java.lang.*; import javax.swing.JOptionPane; class Example { public static void main (String[ ] args) { String value1,value2,value3,value4,value5 ; float f1,f2,f3,f4,f5 ; float sum ; float Average ; // Read input String from dialog box value1 = JOptionPane.showInputDialog(\"Enter the floating point decimal number\"); f1 = Float.parseFloat(value1); // Convert String to float value2 = JOptionPane.showInputDialog(\"Enter the floating point decimal number\"); f2 = Float.parseFloat(value2); // Convert String to float value3 = JOptionPane.showInputDialog(\"Enter the floating point decimal number\"); f3 = Float.parseFloat(value3); // Convert String to float value4 = JOptionPane.showInputDialog(\"Enter the floating point decimal number\"); f4 = Float.parseFloat(value4); // Convert String to float value5 = JOptionPane.showInputDialog(\"Enter the floating point decimal number\"); f5 = Float.parseFloat(value5); // Convert String to float sum = f1+f2+f3+f4+f5 ; Average = sum/5 ; System.out.println(f1) ; System.out.println(f2) ; System.out.println(f3) ; System.out.println(f4) ; System.out.println(f5) ; System.out.println(\"Math.round(\" + sum + \")=\" + Math.round(sum)); System.out.println(\"Math.round(\" + Average + \")=\" + Math.round(Average)); } }.

1. Write a java program using Dialog boxes that prompt the user to input five floating point decimal
numbers. the program should then add the five numbers, find the average, convert sum and
average to the nearest integer, and print the numbers, sum and average.
Solution
The java program using Dialog boxes that prompt the user to input five floating point decimal
numbers :-
import java.lang.*;
import javax.swing.JOptionPane;
class Example
{
public static void main (String[ ] args)
{
String value1,value2,value3,value4,value5 ;
float f1,f2,f3,f4,f5 ;
float sum ;
float Average ;
// Read input String from dialog box
value1 = JOptionPane.showInputDialog("Enter the floating point decimal number");
f1 = Float.parseFloat(value1); // Convert String to float

2. value2 = JOptionPane.showInputDialog("Enter the floating point decimal number");
f2 = Float.parseFloat(value2); // Convert String to float
value3 = JOptionPane.showInputDialog("Enter the floating point decimal number");
f3 = Float.parseFloat(value3); // Convert String to float
value4 = JOptionPane.showInputDialog("Enter the floating point decimal number");
f4 = Float.parseFloat(value4); // Convert String to float
value5 = JOptionPane.showInputDialog("Enter the floating point decimal number");
f5 = Float.parseFloat(value5); // Convert String to float
sum = f1+f2+f3+f4+f5 ;
Average = sum/5 ;
System.out.println(f1) ;
System.out.println(f2) ;
System.out.println(f3) ;
System.out.println(f4) ;
System.out.println(f5) ;
System.out.println("Math.round(" + sum + ")=" + Math.round(sum));
System.out.println("Math.round(" + Average + ")=" + Math.round(Average));
}
