Array - return greatest value in the array

Question

I am trying to write a program that for the method 'greatest' it will return the greates value in the array between the elements beginning and end.
Below is my code. No errors but I am not getting the desired results.
My output:
2
4
1
5
3
6
My code:
public class Test {
     public void printArray(int x[]){
          for (int i=0; i < x.length; i++)
               System.out.println(x[i] + "");
              System.out.println("\n");
     public static int greatest(int x[], int beginning, int end){
          int i;
          int index = 0;
          int largest = 0;
          for(int z = 0; z < x.length; z++)
             if(largest < x[z])
                largest = x[z];
                index = z;
          return index;
     public static void main(String[] args){
          Test program = new Test();
          int a[] = {2,4,1,5,3,6};
          int val = greatest(a,0,a.length-1);
          program.printArray(a);
}Please, I just would like someone to point out where I need to focus. I do not want anyone to write this. Yes - its for college.
Please and Thank you

Kayaman - once again you have been helpful. Thank you.
So I went to the paper and thought about the logic and rewrote what I had in the method greatest.
* I am passing to the method, successfully calculating the greatest value, but not returning a varialble so the variable val is still not used. Or if I am returning a value I dont see it. *
So, I need to return the value and then call the printArray method to print the outcome.
What line needs to be addressed - remember anyone else reading this, please do not write it for me :-)
     public static int greatest(int x[], int beginning, int end){
           int max = x[0];
             for (int i = 0; i < x.length; i++)
              if (max < x)
     max = x[i];
     System.out.println("The greatest: " + max);
     return max;
Please and Thank you :-)
