always try to use it whenever possible.Extract Method(110) to explain the meaning of a piece of code. after all, a temporary variable is meaningful only in the function where it is located, and has many limitations. A function can be useful throughout the entire life of an object and can be used by other objects. but sometimes, when a local variable causesExtract Method(110) when it is difficult, I will useIntroduceExplaining variable(124 ). Practice 1. Declare a final temporary variable and as

, you can separate these code segments into a function.

. Method (1) declare a temporary final variable and assign the calculation result of some actions in the complex expression to it. (2) Replace the "operation result" part of the expression with the temporary variable. (If this part is repeated in the code, you can replace it one by one.) (3) Compile and test. (4) Repeat the above process to process other similar parts. In this example, we start with a simple calculation: // Double price () {// price = basePrice-quantity
