在java中（非）static方法等的覆盖问题？

都不能，给你个例子自己编译一下试试就知道了。
class Parent
{
public void nonStaticMethod()
{
System.out.println("Parent's nonStatic method is called");
}
public static void staticMethod()
{
System.out.println("Parent's static method is called");
}
}
class Child extends Parent
{
public static void nonStaticMethod()
{
System.out.println("Child's static method is called");
}
public void staticMethod()
{
System.out.println("Child's non static method is called");
}
}
public class Test
{
public static void main(String[] args)
{
Parent p1=new Parent();
Parent p2=new Child();
Child c=new Child();
System.out.print("Parent.static: ");
Parent.staticMethod();
System.out.print("p1.static: ");
p1.staticMethod();
System.o
