Java Day 4 (Assert)

 

Java Day 4

1. What is the output of the following code?
class ShellClass {
    public static void main(String[] args) {
        int x = 10;
        ;;;;;
        ;;;;;
        assert (x > 10);
    }
}

Assert

Assertions are typically enabled when an application is being tested and deployed, but disabled when application is deployed.
-ea is used to enable assertion and -da is used to disable assertion.

class ShellClass {

    public static void main(String[] args) {

        int assert;

    }

}

class ShellClass {

    public static void main(String[] args) {

        assert "Hi";

    }

}

class ShellClass {

    public static void main(String[] args) {

        int x = 10;

        assert x > 10;

    }

}

class ShellClass {

    public static void main(String[] args) {

        int x = 10;

        assert x > 5 : "x is not greater than 5.";

        assert (x > 15) : "x is not greater than 15.";

        assert (x > 8) : "x is not greater than 8.";

    }

}
