Why this problem print 1234, then infinite loop?

Question

int a = 1;

while(a <= 10){
if(a % 5 == 0)
continue;
else
System.out.print(a);

a++;
}

Answer 1

It is because when 'a' becomes 5, continue is executed and it moves back to the while condition and 'a' is never incremented. So the if condition is always true.

Answer 2

5 % 5 == 0
continue loop

after it variable a never increase
