java.lang package provides classes that are fundamental to the design of the Java programming language. This tutorial will take you through all the methods available in java.lang package using a simple and practical example.
Frequently it is necessary to represent a value of primitive type as if it were an object. The wrapper classes Boolean, Character, Integer, Short, Byte, Long, Float, and Double serve this purpose.
The classes String, StringBuffer, and StringBuilder similarly provide commonly used operations on character strings.
Class Throwable encompasses objects that may be thrown by the throw statement. Subclasses of Throwable represent errors and exceptions.
Following are a list of classes under java.lang package. I explained all the methods with lots of examples from each class. Our suggestion is to do lots of hands experience using this tutorial.

>> java.lang Object Class
The Object class, in the java.lang package sits at the top of the class hierarchy tree. Every class is a descendant, direct or indirect, of the Object class. In this article, you will learn all the Object class methods with examples.>> java.lang Boolean Class
The Boolean class wraps a value of the primitive type boolean in an object. An object of type Boolean contains a single field whose type is boolean. In this article, you will learn all the Boolean class methods with examples.>> java.lang Byte Class
In this article, you will learn all the Byte class methods with examples. The Byte class wraps a value of primitive type byte in an object. An object of type Byte contains a single field whose type is a byte.>> java.lang Character Class
In this article, you will learn all the Character wrapper class methods with examples. The Character class wraps a value of the primitive type char in an object. An object of type Character contains a single field whose type is char.>> java.lang Double Class
In this article, you will learn all the Double wrapper class methods with examples. The Double class wraps a value of the primitive type double in an object. An object of type Double contains a single field whose type is double.>> java.lang Float Class
In this article, you will learn all the Float wrapper class methods with examples. The Float class wraps a value of primitive type float in an object. An object of type Float contains a single field whose type is a float.>> java.lang Long Class
In this article, you will learn all the Long wrapper class methods with examples. The Long class wraps a value of the primitive type long in an object. An object of type Long contains a single field whose type is long.>> java.lang Integer Class
In this article, you will learn all the Integer wrapper class methods with examples. The Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int.>> java.lang.Number Class
In this tutorial, we will discuss the important and commonly used Number class methods with examples.>> java.lang.Package Class
In this tutorial, we will discuss the important and commonly used Package class methods with examples.
