One interesting application of computers is to display graphs and bar charts. write an application that reads five numbers between 1 and 30. for each number that’s read, your program should display the same number of adjacent asterisks. for example, if your program reads the number 7, it should display . display the bars of asterisks after you read all five numbers.

The answer to this question can be given by program that  are as follows

import java.util.*;

//import package for taking input from user.

public class Main   //define class

{

public static void main (String ag[] )   //define main function

{

 int number;

 Scanner input = new Scanner(System.in);

 for (int i = 0; i < 5; i ++)                       //loo for input.

 {

 System.out.print ("Enter a number between 1 - 30:  ");

 number = input.nextInt();          //input number by the user.

 }

 asterisk();           //calling function.

 }

public static void asterisk()          //defination of function.

{

    //body of function.

    int n;                   //local variable.

 for (n= 0; n <= 30; n++)                  //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );                  //print value.

 }

 for (n= 0; n <= 30; n++)         //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );     //print value.

 }

 for (n= 0; n <= 30; n++)          //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );          //print value.

 }

 for (n= 0; n <= 30; n++)            //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );               //print value.

 }

 for (n= 0; n <= 30; n++)             //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );             //print value.

 }

}

}

Output:

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 1  

Enter a number between 1 - 30: 3

Enter a number between 1 - 30: 4

Explanation:

In this program we take 5 time input from the user and print the value in the form of (*) that can be explain in above output section.In that program we use printf method that is also used for print the value.
