This unit provides an overview of the java.lang package by explaining its classes, interfaces, and exceptions.
This unit provides an overview of the java.lang package by explaining its classes, interfaces, and exceptions.
It explains the importance of the java.lang package in Java programming.
You will learn about the importance of the Object class, which is the super class for all Java classes. The unit also explains how the Class class encapsulates the run-time state of an object or interface.
It also defines how the ClassLoader class loads the classes at run time.
You will learn about the Cloneable and Comparable interfaces and how they are implemented in programs. This unit explains the methods of the String and StringBuffer classes.
It describes the immutability of string objects in a program.
You will also learn about the implementation of the ?equals? method in a program. Additionally, this unit explains the difference between the implementation of the equals method and the == operator. This unit describes the ways to perform arithmetic operations using the methods of the Math class in the java.lang package.
You will learn the importance of wrapper classes in this package.
You will also learn to wrap primitive data types in wrapper classes, and use the methods of the wrapper classes for data type conversions.
