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);
}
