Thread: ArrayOutOfBound exception

So I cant for the life of me figure out why I am getting this OutOfBound exception and why the program wont work.

public class test {
	public static void main(String[] args) {
 
		int[] array = {58,24,13,15,63,9,8,81,1,78};
 
		Out.println(java.util.Arrays.toString(array));
 
		int[] firstArray= new int[array.length/2];
 
		for(int i = 0; i<array.length/2; i++) {
			firstArray[i] = array[i];
		}
		Out.println(java.util.Arrays.toString(firstArray));
 
		int[] secondArray = new int[array.length/2];
 
		for(int i = array.length/2; i<array.length-1; i++) {
			secondArray[i] = array[i];
		}
 
 
 
		Out.println(java.util.Arrays.toString(secondArray));
	}
}

So my goal here is to split this inital array in half and store both of the halves in new arrays.The first half works but the second I cant get to work. When I try to run the program it gives me "Index 5 out of bound for length 5 exception". Now the way I am seeing this is that the second array has the length of 5 and in the for loop we are starting from the 5th position going to the last element in the original array, and copying the values. Why am I getting this error?

PS.I have also tried going backwards, trying to go from the last unit of the array to the middle and i get the same error

Yea I get that but what if I start from index 0 i will just copy the first part of the array than.I've gotten the program to kinda work now, meaning if I put the length of the array to be 10, I get 5 zeros, followed by 9 8.. etc. How do I get rid of the zeros?

Well I've tried making the array the exact size (array.length/2) but than I get the OutOfBound exception. Is the condition of my while loop wrong?

[58, 24, 13, 15, 63, 9, 8, 81, 1, 78]
[58, 24, 13, 15, 63]
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 5
at test.main(test.java:18)

So, the size of the new array is 5, when I print out the array.length/2 it gives out 5. Also when I print out an empty array of lenght/2 it gives out 5 zeros so the array is of length 5.

Yea you were right, I've figure it out.

 
public class test {
    public static void main(String[] args) {
 
        int[] array = {58,24,13,15,63,9,8,81,1,78};
 
        Out.println(java.util.Arrays.toString(array));
 
        int[] firstArray= new int[array.length/2];
 
        for(int i = 0; i<array.length/2; i++) {
            firstArray[i] = array[i];
        }
        Out.println(java.util.Arrays.toString(firstArray));
 
        int[] secondArray = new int[array.length/2];
 
        for(int i = array.length/2; i<array.length; i++) {
            secondArray[i - 5] = array[i];
        }
 
        Out.println(java.util.Arrays.toString(secondArray));
    }
}

Thank you !

Yea ur right..,I'll look into it.
