Add bytes with type casting, Java

Question

I am trying to add two values in a byte array. This is my code:

byte[] ars = {3,6,9,2,4};
ars[0] = (byte)ars[0] + (byte)ars[4];
System.out.println( ars[0] );         


        

Answer 1

byte[] ars = {3,6,9,2,4};
        ars[0] = (byte) (ars[0] + ars[4]);
        System.out.println( ars[0] );

This will work, try it
