What is output of following code ?and why ?

Question

public class Program {
public static void main(String[] args) {
int test = 5;
test = test++;

System.out.println(test);
}
}

Answer 1

Because at first "test" will be evaluated (5) and this value will be used later by the equation operator. After that value of test will be increased to 6 by the ++ operator. But this new value won't be used, test value will be overwritten by the stored 5.

Answer 2

int test = 5; // setting test to 5
test = test++; // setting test to 5.
System.out.println(test); // output is 5

test = ++test; would output 6.

Answer 3

test ++ will make it 6 for the next function or loop
