Does anyone know how to trace arrays in java?? Please help me trace this program !

Question

int [] array = {1,2,3,4,5};
int[] arr2 = new int[2];
doOne(array,arr2);
}// end of main

//
public static void doOne(int[] arr, int[]z){
for (int i=0; i<arr.length; i++)
arr[i] = arr[i]*2;
z[0] = arr[1]+z[1]+3;
}

(Tracing means to write down the execution of the code step by step, showing how the variable changes)

Answer 1

Trace means? What way..? Explain it mmwith what you trying...
In code snippet, z[0] you can write outside of loop, because no value changing, since using constant indexes and z[1] is assigned to default 0 value yet..
Do you want to print array results.?
