java-重写/重载

package day_7_18;public class test3 {    public static void main(String[] args) {        /*AAAA-K()BBBB-K()BBBB-K()void c(AAAA a)void c(AAAA a)void c(BBBB a)         */        AAAA a0=new AAAA();        a0.a();        a0.k();        AAAA a1=new BBBB();        a1.a();        a1.k();        BBBB b0=new BBBB();        b0.a();        b0.b();        b0.k();        b0.c(a0);        b0.c(a1);        b0.c(b0);    }}class AAAA{    void a(){}    void k(){System.out.println("AAAA-K()");}}class BBBB extends AAAA {    void b(){}    void c(AAAA a){System.out.println("void c(AAAA a)");}//重载看引用类型    void c(BBBB a){System.out.println("void c(BBBB a)");}    void k(){System.out.println("BBBB-K()");}//重写看new 对象}
