final modifier

1. Final Cosmetic classthe final modified class cannot be inherited, so the member method of the final class cannot be overwritten, and the class decorated with the final keyword has no subclasses, so the implementation details of the class cannot

Code optimization Details 1, as far as possible to specify the final modifier class, methodA class with the final modifier is not derived. In the Java Core API, there are many examples of final application, such as java.lang.String, where the

To design an inheritance hierarchy at some point, you want to make sure that members are not quilt class overloaded. In Scala, as in Java, you do this by adding the final modifier to a member. For example, you could put a final modifier in front of

The goals of code optimization are:1, reduce the volume of the Code2, improve the efficiency of code operationCode optimization details 1, specifying the final modifier of the class and method as much as possibleA class with a final modifier is not

Final can be modified: attributes, methods, classes, and local variables (variables in methods) The final modified attributes can be initialized during the compilation or runtime, but cannot be changed after initialization. The final modifier

Code optimization is a very important topic. In general, the goal of code optimization is mainly two, one is to reduce the size of the code, and the other is to improve the efficiency of code operation.There are many details of code optimization,

1, as far as possible to specify the final modifier class, method A class with the final modifier is not derived. In the Java Core API, there are many examples of final application, such as java.lang.String, where the entire class is final.

Just like a whale eats shrimp, maybe a two-shelled shrimp is not very useful for a whale, but a lot of shrimp is eaten and the whale is naturally full. Code optimization, perhaps a two optimization, to improve the efficiency of the code is not

Java code optimization is a very important step in Java programming development, Java code optimization to pay attention to detail optimization, a two-detail optimization, the effect is not small, but if everywhere can pay attention to code
