實(shí)例化對(duì)象的方法報(bào)錯(cuò)
Actress actoress=new Actress();
actoress.setName("xxx");
actoress.start();
大佬們
為啥這樣寫(xiě)報(bào)錯(cuò)呢 ？
The method setName(String) is undefined for the type Actress

Actress繼承自Runnable接口，接口沒(méi)有任何的實(shí)現(xiàn)代碼。而Actress類(lèi)本身也沒(méi)有setName方法，因此JVM找不到setName方法會(huì)報(bào)錯(cuò)
