为什么下列代码输出后,screen并未正确显示输入值,而是显示mem的输入值?

Question

import java.util.Scanner;public class InitailTelphone {public static void main(String[] args) {// TODO Auto-generated method stubScanner input=new Scanner(System.in);System.out.println("请输入Screen的值");float Screen=input.nextFloat();System.out.println("请输入Cpu的值");float cpu=input.nextFloat();System.out.println("请输入Mem的值");float mem=input.nextFloat();Telphone phone2=new Telphone(Screen,cpu,mem);phone2.setScreen(Screen);phone2.setScreen(cpu);phone2.setScreen(mem);System.out.println("screen:"+phone2.getScreen());System.out.println("cpu:"+phone2.getCpu());System.out.println("mem:"+phone2.getMem());}}----------------------------------------------------------------------------------请输入Screen的值10请输入Cpu的值20请输入Mem的值30screen:30.0cpu:20.0mem:30.0

Answer 1

Telphone phone2=new Telphone(Screen,cpu,mem);
phone2.setScreen(Screen);
phone2.setScreen(cpu);
// 注意还这个 set 。。 你覆盖了 原来的 screen值。
phone2.setScreen(mem);
System.out.println("screen:"+phone2.getScreen());
System.out.println("cpu:"+phone2.getCpu());
System.out.println("mem:"+phone2.getMem());

}
