Static Inner classes in java

Static inner classes:

• We access static members using class name.
• Defining a class with static keyword is called Static inner class.
• We access static inner class using outer class name.

class Outer
{
	static void m1()
	{
		System.out.println("Outer class m1()...");
	}
	static class Inner
	{
		static void m2()
		{
			System.out.println("Inner class m2()...");
		}
	}
}
class Access 
{
	public static void main(String[] args) 
	{
		Outer.m1();
		Outer.Inner.m2();
	}
}

Creating object of static inner class:

• We can access non static members using object reference.
• We can instantiate static inner class directly with outer class name.

{
	static class Inner
	{
		void fun()
		{
			System.out.println("static class non static fun..");
		}
	}
}
class Access
{
	public static void main(String args[])
	{
		Outer.Inner obj = new Outer.Inner();
		obj.fun();
	}
}
