Why is the output not 1 2 3 4?

Question

public static void main(String[] args) {
int x = 1;

while(x > 0) {
System.out.println(x);
if(x == 3) {
break;
}
x++;
}
System.out.println(x++);
}

The output comes out to be 1 2 3 3
If i write (x=x+1) in the last statement, it comes out to be 1 2 3 4. But if (x++) and (x=x+1) are same, why are the outputs not same?

Answer 1

@ADP , see this ... 👍
//btw the difference caused in above question by ++x& x++ is only in printing

Answer 2

x++ uses the value of x and then increments which basicly means that the old value of x will be used first and then the new value will be used next

++x increments the value of x and then uses it.

++x looks like x+=1.

Answer 3

public static void main(String[] args) {
int x = 1;

while(x > 0) {
System.out.println(x);
if(x == 3) {
break;
}
x++;
}
System.out.println(++x);
}

"x++" and "++x" are not the same.
For the answer "1 2 3 4" you need to use "++x".

Answer 4

Could u explain further please? (x++) is (x=x+1) right?
and (++x) is?

Answer 5
