若函數(shù)和父類同名,參數(shù)相同則覆蓋,否則為重載

public?class?Test11A{

????public?void?somoke()
????{
????????System.out.println("chouyan");
????}

}

public?class?Test11B?extends?Test11A{

????public?void?somoke()//覆蓋父類的somoke方法
????{
????????System.out.println("bu?chou?yan");
????}
????public?static?void?main(String[]?args)?{
????????Test11B?test??=?new?Test11B();
????????test.somoke();
????}

}

重載:

public?class?Test11B?extends?Test11A{

????public?void?somoke(String??s)//參數(shù)不同,會重載父類的方法
????{
????????System.out.println(s);
????}
????public?static?void?main(String[]?args)?{
????????Test11B?test??=?new?Test11B();
????????test.somoke();
?????????test.somoke("hello");
????}

}
