我们都知道,静态static方法中不能调用非静态non-static方法,准确地说是不能直接调用non-static方法。但是可以通过将一个对象的引用传入static方法中,再去调用该对象的non-static方法。
//A ststic method cannot call a non-static method, but we can transfer a object reference, which include a non-static metho to the static method, thus, wo can call that non-static method in a indirect way.
public class StaticMethodTest{
void NonStaticMethod(){
System.out.println("This is a non-sataic method.");
static void StaticMethod(StaticMethodTest s){
System.out.println("This is a static method.");
s.NonStaticMethod();
}
StaticMethod(sObj); //在主函数中可以直接调用静态方法
}
}
