Types and Expressions

Recall that a variable of type byte can store values in the range -128 to 127. The statements

byte x = 127;

x++;

cause a “byte overflow.” Some languages consider this an error, but Java computes x++; by “wrapping around” to negative numbers. For example, 127 + 1 is − 128. Determine the output of the following segment:

1. byte x = 127;

2. int y = x;

3. x++;

4. y++;

5. System.out.println(x);

6. System.out.println(y);

Does changing line 3 to x = x + 1; generate a syntax error? If not, what is the output? Does changing line 4 to y = y + 1; cause an error? If not, what is the output?
