Number of inputs represented as * in java

Corcs001

Hi,

I am inputting numbers and counting the amount that are entered but I want to represent each number entered as a star. So for each number that is entered a star should appear.

Here is what I have so far.

import java.io.*;


public class Main {

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

int mark = 0;
int no_of_marks1 = 0;
int no_of_marks2 = 0;
int no_of_marks3 = 0;
int no_of_marks4 = 0;

BufferedReader br = new BufferedReader(newInputStreamReader(System.in));


while(mark < 101)
{
System.out.println("Input mark: ");
mark = Integer.parseInt(br.readLine());

if((mark >= 0) && (mark < 30))
{
no_of_marks1++;

}

if((mark > 29) && (mark < 40))
{
no_of_marks2++;

}

if((mark > 39) && (mark < 70))
{
no_of_marks3++;

}

if((mark > 69) && (mark < 101))
{
no_of_marks4++;

}

if(mark > 100)
{
break;
}


}



System.out.println("\nResults:\n");
System.out.println("0-29: " + no_of_marks1 + "\n");
System.out.println("30-39: " + no_of_marks2 + "\n");
System.out.println("40-69: " + no_of_marks3 + "\n");
System.out.println("70-100: " + no_of_marks4 + "\n");

So instead of the above display, it would look like the following or something similar:


0-29 *******

30-39 ***

40 - 69 *****

70-100 *********

Any help appreciated!

Try the following

System.out.println("\nResults:\n");
System.out.print("0-29: ");
int i =0;
while(i < no_of_marks1){
System.out.print("*");
i++;
}
System.out.println();
System.out.print("30-39: ");
int i =0;
while(i < no_of_marks2){
System.out.print("*");
i++;
}
System.out.print();
System.out.println("40-69: ");
int i =0;
while(i < no_of_marks3){
System.out.print("*");
i++;
}
System.out.print();
System.out.println("70-100:");
i =0;
while(i < no_of_marks4){
System.out.print("*");
i++;
}
System.out.println();

amen

instead of repeating your mark printing you could create a function markPrinting passing the text you want and the number mark counter.

Be lazy and never write the same code more than once.
