Therefore, 0xcafebabe is a negative number, which must be expanded first when adding, so that it becomes 0 xffffffffcafebabe.

Method Overloading A class can define multiple methods with the same name but different parameter lists (parameter types, numbers, and sequences, the corresponding method is selected based on different parameter lists. 14. Scope The position of the variable declaration determines the scope of the variable. The variable declared in the method is called a local variable: the scope is in the current method. The variables declared in the class are c
