Question

I have written the following program in Java to convert long to byte.

    public class LongtoByte 
    {
            public static void main(String[] args)
            {
                long a=222;
                byte b=(byte)(a & 0xff);
                System.out.println("the value of b is" +b);

            }
    }

The problem is I get the result -34 for the variable b.

Please tell me how to get the correct value. I want the value in bytes only.

Answer 1

Java’s types are signed, bytes allow numbers between −128 and +127.this is the reason you were getting −34 for 222 value

     long a=121;
     byte b=(byte)(a );
     System.out.println("the value of b is" +b);
