Split Temporary Variable

Latest revision as of 03:11, 25 November 2010

This is when you have create a temporary variable that you use all the way through a method.

   foo() {

       int temp = 2 * (height + width);

       System.out.print(temp);

       temp = height * width;

       System.out.print(temp);

   }

The variable has two different meanings at various stages of the method. Give each variable a descriptive name making it easier to understand the code.

   foo() {

       int perimeter = 2 * (height + width);

       System.out.print(perimeter);

       int area = height * width;

       System.out.print(area);

   }
