java接口通俗理解，java中的接口实例及其讲解

对于java接口通俗理解，java中的接口实例及其讲解，很多网友还不是很明白，今天艾巴小编收集了这方面的知识，就将其分享出来。

操作方法：

1.首先，我们实现一个简单的接口定义。接口USB { public void print()；}你不能在接口中实现函数的方法，也就是说，你不能这样做。接口USB { public void print(){ system . out . println(' hello world ')；};}

2. Next, we use a class to implement this interface. That is to say, it is a concrete process. For example, class computer implements the USB {@ override public void print () {//Todo automatic generation method stubSystem.out.println ('I am a computer'); }

3. Next, you can implement this class in the main function. The following example is public static void main (string [] args) {computercomputer=newcomputer (); Computer. Print (); }

4. Next, inherit multiple interfaces. The following example. Interface USB {public void print (); } interface call {publicovoid callyou (); }

5. The following is implemented with classes. The following example: class computer implements usb, and calls {@ override public void print () {//Todo automatic generation method stubSystem.out.println ('I am a computer'); } @ override public void callyou () {//Todo automatically generated method stubSystem.out.println ('I will call'); }}

6. Just implement it again in the main method.

以上知识分享到此为止，希望能够帮助到大家！
