Can be used directly:map{Put ("test1", "test11");Put ("Test2", "test11");}}; To initialize.In the online search, this is the use of anonymous classes in the way to initialize. The first layer {} is the definition of an anonymous class, and the second layer {} is the definition of the initialization function.But what is not figured out is that this should be an in

of each line. Python open source, charging difficult advantages: no Java Popular Cons: There is not much sense of existence in the language I think the disadvantage is: 1, Python is a bit slow, it seems cpython (official implementation) did not develop the JIT interpreter plan. Now there is a pypy project to do this thing, progress is good, worth looking forward to. Of course, Python, it's really not impor

Basic Theory: ----------------------------------------------------- Java internal class: the definition of an internal class is defined within another class. The reason is: 1. An internal class object can access the implementation of the object created for it, includin

); System.out.println (Mc.getval ()); }}View CodePre-defined functional interfacesUsually we don't need to define the function interface ourselves, Java has provided some predefined functional interfaces. Unaryoperator Applies a unary operation to an object of type T and returns the result, with the method named apply. Binaryoperator Operates on two objects of type T and returns the result, with the method n

Java Collection frameworks such as set, map, and list do not provide any simple method for initialization. Each time a set is created, values must be added one by one. For example CopyCode The Code is as follows: Set Letter. Add ('A '); Letter. Add ('B '); //... Very tedious. But use an anonymous internal class. It can be slightly simpler. Copy code The Co

What are the main areas and what kind of scenarios are these advantages? Reply content:Both sides can list many advantages, but the problem is too hasty ... Here's a few words for Java: The quality of the JVM is much better than Python's virtual machines. A high-quality python interpretation environment can be built in the JVM environment, not in the reverse.
