Java assert printing

Question

I need to print the statement in the assertion to the console when condition is true in eclipse. How?

public static void main(String[] args) {
    try {
        assert(args[0].equals("x")): "kate";
    } catch(Error e) {
        System.out.print("ae ");
    } finally {
        try {
             assert(args[0].equals("y")): "jane";
        } catch(Exception e2) {
             System.out.print("ae2 ");
        }
    }
}

Answer 1

You need to:

• Select Run → Run Configuration → Right click on Java Application → New → Go to Arguments tab → Write -ea in VM arguments:

Now, when you have something like:

assert(1==2) : "Error!!!";

You'll see in the console:

Exception in thread "main" java.lang.AssertionError: Error!!!
