Java lang package include fundamental  classes that design this Languages.  This lesson introduces you the fundamental  classes like object,  class loader,  thread class etc ,  string class is immutable  so string buffer and builder are used to make changes in String . Number class include math class and character class includes escape sequence  so all these are really useful and thus included in Java.lang.package

Overview

This lesson includes all the fundamental  classes like object class,  class,  class loader, compiler class,  package,  process,  runtime, system,  throwable, errors,  exceptions etc

Some Fundamental Classes

String class is used to create and manipulate string,  whenever it encounters a string literal, compiler  creates a string object. String class is immutable (string object can't be changed),so to make lots of changes we use string buffer and string builder classes.

Java-string Class

Java provides a wrapper class number to Create object of primitive data types. This is done by compiler called autoboxing. Important  methods implemented  inside number classes are compareTo(), valueOf(), parseInt(), abs(), sqtr(),, exp(),are inside Maths class

Number Class

Java provides wrapper class character to convert a primitive char into character object. This concept is called auto boxing. Escape sequence use in printing un printable characters.  Character methods are also covered in this lesson. This lesson gives you an overall implementation  of character class inside the Java. lang. Package.
