(3)最后解释一下为什么interface的成员变量必须是public static final的。 我在Google上搜到了一篇比较不错的文章《Why do we have only public static final variables in interfaces?》,下面大概翻译一下(有改动): 接口定义了行为的协议,而不是行为如何执行实现。实现接口的类支持该
Interface looks like a class but it is not a class. An interface can have methods and variables just like the class but the methods declared in interface are by default abstract (only method signature, no body, see:Java abstract method). Also, the variables declared in an interface are pub...

In subject area:Computer Science An 'Interface Standard' in the context of Computer Science refers to a set of standard names for functions and variables that ensure uniform interpretation of their attributes. It allows for both technical and semantic interoperability by enabling software to test the...

LocalVariable is used for all local variables in Java source code. If a local variable has a parameterized type, a type argument, or an array type of one of the previous types, a LocalVariableType should be created for that local variable as well. Since: 24 See Also: LocalVariableInfo ...
In its most common form, an interface is a group of related methods with empty bodies. A bicycle's behavior, if specified as an interface, might appear as follows: interface Bicycle { // wheel revolutions per minute void changeCadence(int newValue); void changeGear(int newValue); void spe...
Constants are the constant things in a project. I mean, it is safe to assume that any project would have some kind of constant values used across the code. The common practice in Java is to declare them as public, static and final variables so that they can be easily referenced wherever...
Let’s define a few constants and variables that we will use to maintain the state machine: // definition of the keyboard PS/2 state machine #define PS2START 0 #define PS2BIT 1 #define PS2PARITY 2 #define PS2STOP 3 // PS2 KBD state machine and buffers int PS2State;...
