Gerard Thank you for your help with this.

Thank you for your reply showing how to get 20 random integers in the array. How though can I refer to each integer in the array so I can do separate calculations on each pair of integers?

I assume you mean I call it four times as I use four numbers. If I just want to add 2 numbers together then I assume that I just use   rand.nextInt(2)

Could I then loop through 5 times to get 20 numbers?

I am later using this to produce 20 random numbers but first want to do calculations with each pair of random numbers.

Please help I am trying to get x below to equal the sum of the first two random integers and not integers 3 and 4. But the program doesn't add togetehr -7 and 12 but instead adds together later random integers that are created to get an answer of 14. What do I need to do? Thanks for any assistance. This is my first time using JAVA and I am struggling.

int rand_int1 = -rand.nextInt(20);
int rand_int2 = rand.nextInt(20);
int x;
x = (-rand.nextInt(20) + rand.nextInt(20));
System.out.println("Answer is: "+x);
System.out.println("Add this number: "+rand_int1);
System.out.println("and this number together: "+rand_int2);

run:
Answer is: 14
Add this number: -7
and this number together: 12
BUILD SUCCESSFUL (total time: 0 seconds)

The program will be used to create 20 random integers once it is fully written but I am not able to get the first random numbers to be used in the program.
