Java is object-oriented to a great extent, it is not a pure object-oriented language. One of the reasons Java is not purely object-oriented is that not everything in it is an object. For example, Java allows you to declare variables of primitive types (int, float, boolean, etc.) that aren't objects. And Java has static fields and methods, which are independent and separate from objects.

An assertion is a statement enables us to test our assumptions about the program.
Each assertion contains a boolean expression that our believe will be true when the
assertion executes. If it is not true, the system will throw an error.
