我们可以在Java 9的接口中使用私有方法吗？
是的，自Java9开始，您可以在接口中使用私有方法。
示例
interface MyInterface {
public abstract void demo();
public default void defaultMethod() {
privateMethod();
staticPrivateMethod();
System.out.println("This is a default method of the interface");
}
public static void staticMethod() {
staticPrivateMethod();
System.out.println("This is a static method of the interface");
}
private void privateMethod(){
System.out.println("This is a private method of the interface");
}
private static void staticPrivateMethod(){
System.out.println("This is a static private method of the interface");
}
}
public class InterfaceMethodsExample implements MyInterface {
public void demo() {
System.out.println("Implementation of the demo method");
}
public static void main(String[] args){
InterfaceMethodsExample obj = new InterfaceMethodsExample();
obj.defaultMethod();
obj.demo();
MyInterface.staticMethod();
}
}输出结果
This is a private method of the interface This is a static private method of the interface This is a default method of the interface Implementation of the demo method This is a static private method of the interface This is a static method of the interface
