Java - Local Class and Anonymous Class

Local Class and Anonymous Class

Local Class: If we declare an inner class within a method such class is known as local class.
Use it if you need to create more than one instance of a class and access its constructor, or introduce a new, named type.
Example:



public class A
{
void fun()
{
class MyInnerClass
{
System.out.println("This is my Inner class");
}
}
}

Anonymous Class: The class which declared in a method without name is called as anonymous class.
Use it if you need to declare fields or additional methods and need to use local class at once.

Example (Syntax):

HelloWorld College = new HelloWorld()
{
String collegeName = "ABC College";
public void sayName()
{
System.out.println("College Name: " + collegeName);
}
};


Note: HelloWorld is a interface which already defined and college is anonymous class.
