Properly Accessing your Outer Class

Recently, during my work, a colleague indicated a way to make it obvious that a variable used in an Inner class, belonged to the outer class. In order to prevent being ambiguous.

	package mrbear;
	/**
	*
	* @author MrBear
	*/
	public class MrBear
	{
	private String world = "The world.";
	public class FirstInner
	{
	public void printWorld()
	{
	// ambiguous
	System.out.println(world);
	}
	}
	public class SecondInner
	{
	public void printWorld()
	{
	// not ambiguous
	System.out.println(MrBear.this.world);
	}
	}
	}

view raw MrBear.java hosted with ❤ by GitHub

I didn't know that could work.
