Can anybody explain this to me

Question

How many times will the following loop run?
for(int i=2;i<10;i=i*i){
System.out.println(i)
}

Answer 1

Pro tip:
Copy the code into a script on playground and find out by yourself how many times the loop will run! Add the missing ; at the end of the println

Answer 2

You can use a debugger to see how the code works and the variables change through the flow of the code
