When I start my code
for (byte i = 0; i < 1000; i++) {
System.out.print(i);
}
I get infinite loop. Why?

Simply because byte value starts to overflow after its max value i.e. 127.
The value of i will go up to 127 and then will overflow to -128 and then increment back to 127. This process will therefore never satisfy your for loop termination condition, and thus loop forever.

after 127 it will wrap to -128 and count all the way up to 127 again. All of the possible values are less than 1000 so it won't ever exit – xkickflip Jul 12 '15 at 22:55

I know, the size of `byte` is [-128 to 127]. But it doesn't explain the infinite loop. – JohnWinter Jul 12 '15 at 22:52

How is the loop supposed to end if it is not possible for i >= 1000 to be true? – Chris K Jul 12 '15 at 22:55
