Chapter 3, Problem 5PE

Explanation of Solution

a.

Program code:

Percentages.java

//import the requird packages

import java.io.*;

//define a class Percentages

class Percentages

{

//define a method computePercent()

public static void computePercent(double num1,double num2)

{

//print the percentage values

System.out.println(num1+" is "+((num1/num2)*100)+" percent of "+num2+".");

}

//define the main method

public static void main (String[] args)

{

//declare two double values

double num1=2.0,num2=5...

Explanation of Solution

b.

Program code:

Percentage2.java

//import the requird packages

import java.util.Scanner;

import java.io.*;

//define a class Percentages

class Percentage2

{

//define a method computePercent()

public static void computePercent(double num1,double num2)

{

//print the percentage values

System.out.println(num1+" is "+((num1/num2)*100)+" percent of "+num2+".");

}

//define the main method

public static void main (String[] args)

{

        //declare two double variables

        double num1,num2;

        //create the object of Scanner

        Scanner sc=new Scanner(System.in);

        //prompt the user to enter the values

        System.out.println("Enter two numbers:");

        //scan for the values

num1=sc...
