为什么输出是5.0不是6.0

Question

package com.imooc;public class InitailTelphone { public static void main(String[] args) { // TODO 自动生成的方法存根 //通过无参构造方法可以创建对象 Telphone phone=new Telphone();  //通过有参构造方法可以创建对象      Telphone phone2=new Telphone(5.0f,1.4f,2.0f);       phone2.setScreen(6.0f);      System.out.println("screen:"+phone2.getScreen());       }}

Answer 1

//我的输出就是6.0啊

package imook;

public class Telphone {

     float Screen;

     float op;

     float lp;

     public Telphone(){

     

     }

     public Telphone(float Screen,float op,float lp){

    this.lp=lp;

    this.op=op;

    this.Screen=Screen;

     }

protected float getScreen() {

return Screen;

}

protected void setScreen(float screen) {

Screen = screen;

}

protected float getOp() {

return op;

}

protected void setOp(float op) {

this.op = op;

}

protected float getLp() {

return lp;

}

protected void setLp(float lp) {

this.lp = lp;

}

}
