先看题：
class Base {
private String name = "Base";
public void method() {
System.out.println("In Base method...");
}
public static void staticmethod() {
System.out.println("In Base staticmethod...");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
class Sub extends Base {
private String name = "Sub";
public void method() {
System.out.println("In Sub method...");
}
public static void staticmethod() {
System.out.println("In Sub staticmethod...");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class Test {
public static void main(String[] args) {
Base ob = new Sub();
System.out.println(ob.getName());
ob.method();
ob.staticmethod();
}
}
运行结果：
Sub
In Sub method...
In Base staticmethod...
之所以这样是静态方法不存在重写覆盖的问题。看你申明变量时是什么类型的，就调用这个类型的方法
Base ob = new Sub();类型是Base类型所以调用base的静态方法。
