assertions

[vandu matcha]

Given code as

class A {
void m1(int i) {
int j = i % 3;
switch (j) {
case 0: System.out.print("0"); break;
case 1: System.out.print("1"); break;
default:
assert j == 2;
System.out.print(j);
}}
public static void main (String[] args) {
A a = new A();
for (int i=5; i >= -1; i--) {a.m1(i);}
}}

output is
With assertions enabled it prints 210210 followed by an AssertionError message.
With assertions disabled it prints 210210-1

i am bit confused...i guess the output is 210000 as j will never be 2 after the first time it executed...please help me

% is Java's remainder operator, which yields "the remainder of its operands from an implied division." So 2%3 is 2, because 2 divided by 3 is 0 with a remainder of 2.

Does this answer your question? Or were you thinking that the assertion statement might affect this?
