java 16.1

Question

How many times will the following loop run?
for (int i = 2; i < 10; i = i*i) {
System.out.println(i);
} i think it should be 3 or until i<10 help me

Answer 1

The next value of i is calculated by multiplying with itself. As long as it's smaller than 10, the loop runs.
2 is the starting value
2 * 2 = 4 is smaller than 10, ok
4 * 4 = 16 the loop condition is false.

So the loop runs only twice, with values of 2 and 4.
