Question

It's not really an infinite loop.

Answer 1

Here you can see it:

A do while loop executes once and then checks the condition. If the condition is true, repeat the loop.

A while loop checks first the condition and only if the condition is true it executes the code.

Answer 2

Have you tried it in the code playground?
It is an infinite loop.

int x = 0;
Do{
System.out.println(x); //output: 0
x++; //x = 1
}while (x > 0) //true -> 1 > 0

Answer 3

No it is not.
x will reach Integer.MAX_VALUE after a time and then adding 1 to it will set it to Integer.MIN_VALUE which is -2^31.

Answer 5

Real infinity does not exist either. No matter which data type you choose (int, long, BigInteger), you will find a technical barrier. But theoretically, this condition leads to an infinite loop.

Answer 6

My problem is not about condition checking, it is about the variable size of an int.

Answer 7

A while(true) loop would be pretty much infinite. Or just a different break condition would help

Nice observation!
