for loops

Question

please help:
why do I get different outputs from this code:
1. int i;
for(i = 0;i<100;i++);
System.out.println(i);
2. int i;
for(i = 0;i<100;i++){
System.out.println(i) ;
}
please help, how does the insertion of semicolon and curled brackets affect the output..?

Answer 1

1 : 100
2: 0 to 99

Answer 2

in first case there is no loop body so, only i gets incremented , in the end i is 100 it checks and condition doesn't holds, but the value for i is still 100

in second case there is loop body inside {} braces, so till the condition holds it prints 0 till 99 , but not 100 as before entering the loop body condition is checked , and 100 is not< 99. so end of loop
