any resource or performance (memory or cpu) issue does this code present ?

[Raj Ohadi]

If I have a code like

int count = 0;
int N = 10000000;
while(true) {
 
    if(count++ > N) {
         break;
    }

}

When N is big number, the code keeps looping for N times. My question is --- when program loops for N times, does it eat lot of memory or what ? what kind resource problem it may cause when N is big ? what kind of performance problem it may cause (ignore the time that it takes toloop, that's not an issue) ?

This is the sort of question that is best answered empirically. What did you observe when you ran it?

[Campbell Ritchie]

It probably doesn't require a lot of memory; the many numbers can all fit into one int space, which is updated every iteration.
I suggest you change it to read

long start = System.nanoTime();
int count = 0;
int N = 10000000;
while(true) {
 
    if(count++ > N) {
         break;
    }
}
System.out.printf("It took %d\u03bcs to run%n", (System.nanoTime() - start) / 1000);
