import the required classes is a prerequisite for our construction program to master. This week's learning Focus: how the user-defined class is defined, how the program is constructed, and the object's declaration is mastered. In this stage of learning, static methods, non-static methods (examples) of the distinction, use has caused me a certain degree of confusion and small trouble, in the fourth chapter of the classroom practice, there is a question "a class of non-static methods can access s

, including arrays. Objects combine data and methods to encapsulate them in a class so that each object can implement its own characteristics and behavior. C + + allows functions and variables to be defined as global. In addition, the structure and union in C + + is removed in Java, eliminating unnecessary hassles.Four, stringC does not support string variables, using a null terminator in a C program to represent the end of a string, in Java, strings are implemented using class objects (STRINR a
