Final Example]

1. Final is used to apply restrictions on class, method and variable. Final class can’t be inherited, final method can’t be overridden and final variable value can’t be changed.
2. Final is a keyword.

class FinalEg
{
   public static void main(String[] args) 
   {
      final int x = 600;
      x = 400;// Compile Time Error
    }
}

Finally Example

1. Finally is used to place important code, it will be executed whether exception is handled or not.
2. Finally is a block.

class FinallyEg
{
	public static void main(String[] args) 
	{
		try {
			int x = 500;
		} catch (Exception e) {
			System.out.println(e);
		} finally {
			System.out.println("finally block is executed");
		}
	}
}

Finalize Example

1. Finalize is used to perform clean up processing just before object is garbage collected.
2. Finalize is a method.

class FinalizeEg 
{
	public void finalize() 
        {
	   System.out.println("finalize called");
	}

	public static void main(String[] args) 
        {
		FinalizeExample f1 = new FinalizeExample();
		FinalizeExample f2 = new FinalizeExample();
		f1 = null;
		f2 = null;
		System.gc();
	}
}
