. 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
