function on a formal parameter is handled as an indirect addressing, i.e. byThe address stored in the stack accesses the argument variable in the keynote function. Because of this, any action taken by the modulated function on the parameter affects the argument variables in the keynote function.The theory is not much to say,The following code provides a detailed explanation of this (actual argument, the an

The most important theme of the Java One Congress is "the future direction of Java", and Sun has a great action for the Java language itself, for EE platform, for development tools. The foreign Java community likened. NET's attack to "Empire Strikes Back", while Java one, of course, is "The

this in the method represents the object reference that is currently calling this method. This specific usage is shown in a few ways:1. When there are multiple overloaded constructors, and one constructor needs to call another to construct it, it is called with this (Param) in its first row and only in the first row;2. When a method in the object needs to call the other methods in this object, use this as the keynote, or do not write, in fact, the de

An important function of a reference is as a function parameter. The previous C language function parameter passing is the value of the pass, if there are large chunks of data passed as parameters, the use of the scheme is often a pointer, because
parameters to arguments. The formal parameter and the argument one by one correspond, the quantity is consistent, the type is consistent, the order is consistent. Formal parameters do not occupy memory until the function is called, memory is allocated for the parameter when the function is called, the call ends, and memory is freed. Return function: Ends the function's run. Returns the main function with the result of the operation. If the return statement is: Return, it means that only the cal
