Thread: Java program to generate 10 random integers and then sum computed

So I'm trying to have the program generate 10 random integers and then have the sum computed. Please help.

import java.util.Random;
import java.util.*;

public final class Sum10RandomIntegers
{
public static final void main(String[] args)
{

int sum;
int randomInt;

System.out.println("Generating 10 random integers in range 0 to 10.");

Random randomGenerator = new Random();

for (int random = 1; random <= 10; ++random)
{
randomInt = randomGenerator.nextInt(10);
sum = (int)(Math.random() * 10);
System.out.println(" " + sum);
}

}


}

Hello Lizard and welcome to the Java Programming Forums

You were very close with this.. You just needed to do the calculation.

import java.util.Random;
import java.util.*;
 
public final class Sum10RandomIntegers {
    public static final void main(String[] args) {
 
        int sum = 0;
        int randomInt;
        [B]int result = 0;[/B]
 
        System.out.println("Generating 10 random integers in range 0 to 10.");
 
        Random randomGenerator = new Random();
 
        for (int random = 1; random <= 10; ++random) {
            randomInt = randomGenerator.nextInt(10);
            sum = (int) (Math.random() * 10);
            System.out.print(sum + " ");
            [B]result = result+sum;[/B]
 
        }
        System.out.println();
        System.out.println("Result = " + result);
    }
 
}

Example output:

Generating 10 random integers in range 0 to 10.
8 5 3 5 3 7 8 6 3 5
Result = 53
