an array index out of bound exception: 2

[divinity02]

hi
I am getting this an java.lang.array index out of bound exception: 2 error - I am wondering if this is where am getting it. look it over many times, and I know you all are tired of me but am learning.

I like the array but it can be annoying at time.

here is what I am talking about.

 int[] arrgsalary = new int [2];
        int lowest = arrgsalary[0];
        int highest = arrgsalary[0];

        System.out.println("please enter the gross salary for 2 employees");

        for (i = 0; i<arrgsalary.length; i++) - I am wondering if this is the error here.
        {
            System.out.println((i+1) + ":");

            arrgsalary[i]= userinput.nextInt();

            if (arrgsalary[i] > highest)
            {
                highest = arrgsalary[i];
            }
            if(arrgsalary[i] < lowest)
            {
              lowest = arrgsalary[i];

              System.out.println("the highest gross salary is:$ " + gsalary[i]);
              System.out.println("the lowest gross salary is:$ " + gsalary[i]);
            }
        }


        this is the output

hey

I found the problem. the java lang.arrray index out of bound exception: i delete it and it working but my calculation is out of whack.
am not getting the result that i am looking for. explain to me what and where my calculation is wrong and out of whack

can somebody tell me how do I implement java random generator numbers in a game. have been trying to build this multiplication game that need to generate random numbers. how do i get to make it generate random number so that I can multiply it and for it to be reteriate until the user get it either right or wrong.

i need it to generate different random numbers from the 2 times table, 3 times table and so one. have tried out everything but it is not working

Oh dear, divinity02

139 posts and you don't yet know that you must:
1 start a new thread for a new question
and
2 show what you have done

[Taywin]

A quick answer for your random number generator... You may start with Random class from Java...

I am wondering if this is where am getting it. look it over many times, and I know you all are tired of me but am learning.

1. To be precise to you question. Put at try around your code. catch your exception and print the stack trace. That will definitely give you the point of origin for your exception.

2. You claim to be learning but in a very recent post of yours, myself, @James and @Stlutuske suggested a bunch of methods for debugging out of which printStackTrace is definitely one.
