Java编写缺觉IQ损失计算程序出现编译报错求解决

编译错误修复 #

三个cannot find symbol报错的原因是ConsoleIO.readInt是方法，调用Java类方法必须添加括号()，你漏写括号后编译器会将其识别为类的成员变量，自然无法找到对应符号。
修复方法：将SleepCalc类中三处ConsoleIO.readInt统一修改为ConsoleIO.readInt()。

业务逻辑修复 #

Sleep工具类修正 #

原Sleep类存在以下问题：

• 方法定义不符合需求：要求iqLoss接收代表单晚缺觉小时数的整数参数，原代码为无参定义
• 内部变量未初始化就使用：iq、totaliqloss均未赋值就参与运算，运行会报错
• 边界逻辑冗余：缺觉时长等于2时会同时命中两个判断分支
  修正后代码：

public class Sleep{
  public static int iqLoss(int lackHour){
    if(lackHour >= 2){
      return 2;
    } else {
      return 1;
    }
  }
}

SleepCalc主类修正 #

原主类存在以下问题：

• 调用Sleep.iqLoss()时未传入计算好的缺觉时长参数
• 同名变量重复赋值逻辑易出错，缺觉时长和IQ损失值混用同一个变量
• 缺少最终计算结果的输出逻辑，无法看到最终IQ值
• 存在拼写错误：noramlly应为normally
  修正后代码：

public class SleepCalc {
    public static void main(String[] args) {
        int iq;
        int normalsleep;
        
        System.out.println("What is your IQ (when fully rested)");
        iq = ConsoleIO.readInt();
        
        System.out.println("How many hours do you normally get");
        normalsleep = ConsoleIO.readInt();
        
        System.out.println("How many hours did you get last night?");
        int sleep = ConsoleIO.readInt();
        int loss1 = Sleep.iqLoss(normalsleep - sleep);

        System.out.println("How many hours did you get the night before last?");
        int sleep2 = ConsoleIO.readInt();
        int loss2 = Sleep.iqLoss(normalsleep - sleep2);
        
        System.out.println("How many hours did you get the night before the night before last?");
        int sleep3 = ConsoleIO.readInt();
        int loss3 = Sleep.iqLoss(normalsleep - sleep3);
        
        int finalIq = iq - loss1 - loss2 - loss3;
        System.out.println("Your current IQ after lack of sleep is: " + finalIq);
  }
}
