Assertion doubt

[Ash Gill]

i am trying to get an assertion error, however, When i compile my program from the command line, the assertion error is never thrown and the program compiles fine

public class Assertions {

public static void main (String [] args){
int x = 1;
int y = 0;
boolean b = false;
assert (b): "simple assertion";
reallySimple(x);
new Assertions().simple(y);
assert false;
}

static void reallySimple (int x)
{
assert (x != 0);
}
private void simple (int x)
{ 
assert (x != 0): "y = "+x ;
}

}

can anyone help to figure out that why isn't the assertion error thrown anywhere in the above code.

AssertionError is a RuntimeException. exception always throws at runtime. so what happend when you run the program with -ea flag? i.e, java -ea YourApp.

note: by default assertion is disabled!

yes, they work fine. thanks a lot. i was getting the concept wrong, good that i tried out an example.
