how does this Equality Operator work?

Question

================================================
for(int x=10; x<=40; x=x+10) {
if(x == 30) {
continue;
}
System.out.println(x);
}
/* Outputs
10
20
40
*/

==========================================

why out come is 10,20,40
it say if x is 30, continue
but x has never been 30

Answer 1

Why won't x be 30?

First iteration: x = 10
Second iteration: x = 20
Third iteration: x = 30 (continues)
Fourth iteration: x = 40
Loop ends

Answer 2

i meant how can you get outcomes of 10,20 in the first place. it says if x==30.
10 == 30 is obivously not ture

Answer 3

Note that the System.out.prinln(x); is outside the if block.

The code means that if x == 30, then you "continue", else you show x to the screen and start again from the top with value of x = x + 10.
