Deleting from an Array?

Question

I've written the following code to move everything in my array up one and replace the final value with a -1, yet it does not work and I can't figure out why...any ideas?
for(int j=1; j <= buffer.length-1; j++){
          buffer[j-1]=buffer[j];
          buffer[buffer.length-1]=-1;
          }It's kinda messing up the whole effect of my program.

Answer 1

Works .....
public class Primitives
public static void main(String[] a)
int[] buffer = new int[]{0,1,2,3};
for(int j=1; j <= buffer.length-1; j++)
buffer[j-1]=buffer[j];
buffer[buffer.length-1]=-1;
for (int i=0; i < buffer.length; i++)
System.out.println(buffer);
