Refactoring:Inline Temp

As I showed in previous post it is useful to use Inline Method when we have a lot of functionality which is on several methods and need to put this functionality to the one method.
In this post I want to show,in my point of view,subtechnique of Inline Method which is called Inline Temp.
Why do we need another technique? As I said in my point of view it is not another technique it is subtechnique of Inline Method.
Here I will use simple example,as usual

public class InlineTempExample{public static void main(String[] args){String s = getStringSum();System.out.println(s)}private static String getStringSum(){int value = 10 + 10;return Integer.toString(value)}}

For this refactoring I need to remove String s from main method

public class InlineTempExample{public static void main(String[] args){System.out.println(getStringSum())}private static String getStringSum(){int value = 10 + 10;return Integer.toString(value)}}

As you can see it is very simple.
Pay attention: in real-world application you can skip this technique for local variables,but if these local variables don’t allow you to do other type of refactoring then you can use Inline Temp technique.
