有一個(gè)錯(cuò)誤不知道怎么改了，求大神幫助
//這是我的定義的類
package com.imooc;
public class FangFa {
private float screen;
private float cpu;
private float mem;
public float getScreen(){
return screen;
}
public void setScreen(float newScreen){
screen=newScreen;
}
public FangFa(){
System.out.println("無(wú)參的構(gòu)造方法執(zhí)行了！");
}
public FangFa(float newScreen,float newCpu,float newMem){
screen=newScreen;
? ?cpu=newCpu;
? ?mem=newMem;
? ?System.out.println("有參的構(gòu)造方法執(zhí)行了！");
}
}
//這是主函數(shù)
package com.imooc;
public class FZ {
public static void main(String[] args) {
// TODO Auto-generated method stub
FangFa hello=new FangFa();
FangFa hi=new FangFa(5.0f,1f,2.0f);
}
hi.setScreen(6.0f);
System.out.println("screen:"+hi.getScreen());
}
然后有一個(gè)錯(cuò)誤不知道怎么改了
2015-12-12
hi.setScreen(6.0f);
System.out.println("screen:"+hi.getScreen());
寫(xiě)到main方法里
2016-05-02
main方法的大括號(hào)結(jié)束位置不對(duì)。
2016-03-02
FangFa hi=new FangFa(5.0f,1f,2.0f);里沒(méi)有錯(cuò)誤么
FangFa hi=new FangFa(5.0f,1.0f,2.0f);
