How to add random numbers to some basic while b > a ?

import java.util.Random;

public class WhileLoop {
    public static void main(String[] args) {
        Random random = new Random();

        int a = 1000;
        int b = 0;
        int c = random.nextInt(10);
        int d = random.nextInt(50);
        int sum1;
        int sum2;
        int sum3;
        int sum4;

        System.out.println(c);
        System.out.println(d);
        while(sum4>sum2) {
            sum1 = a + c;
            sum2 = sum1 + c;
            sum2++;
            System.out.println(sum2);

            sum3 = b + d;
            sum4 = sum3 + d;
            sum4++;
            System.out.println(sum4);
        }
    }
}

I have trouble understanding how to add a random number to a number 0-10 and to b the numbers 0-50 until the condition is met a = 1000; b = 0; the condition is b> a

I do not understand what exactly you try to achieve but your code won't compile cause you're using variables you do not have initialized. In the condition in line 18 sum2 and sum4 are declared but not initialized. You didn't assign them values and hence they are in an undifined state. Assign them values and you can at least test your code. If you want to create new random values inside the while loop, then you need to use nextInt inside that loop like:

Random random = new Random();
int a = 1000;
int b = 0;

while(a > b) {
    a += random.nextInt(10);
    b += random.nextInt(50);
    System.out.format("a=%4d, b=%4d%n", a, b);
}
