Java provides a standard class<\/a> library consisting of thousands of class<\/a>es and other reference types.

The\u00a0first half<\/a> of this tutorial on Java inheritance showed you the basics of inheritance, specifically how to use Java’s\u00a0extends<\/code> and super<\/code> keywords to derive a child class<\/a> from a parent class<\/a>, invoke parent class<\/a> constructor<\/a>s and methods, override methods, and more. Now, we’ll turn our focus to the mothership of the Java class<\/a> inheritance hierarchy, java.lang.Object<\/code>.<\/p>\n
