问题描述

我想在Java中设置一个 int 值的限制。我正在创建一个简单的健康系统，我希望我的健康状况保持在0到100之间。我该怎么做？

I want to set a limit to an int value I have in Java. I'm creating a simple health system, and I want my health to stay between 0 and 100. How can I do this?

推荐答案

我建议您创建一个名为Health的类，如果满足约束条件，则每次都检查是否设置了新值：

I would recommend that you create a class called Health and you check every time if a new value is set if it fulfills the constraints :

public class Health {

   private int value;

   public Health(int value) {
      if (value < 0 || value > 100) {
         throw new IllegalArgumentException();
      } else {
         this.value = value;
      }
   }

   public int getHealthValue() {
      return value;
   }


   public void setHealthValue(int newValue) {
    if (newValue < 0 || newValue > 100) {
         throw new IllegalArgumentException();
      } else {
      value = newValue;
    }
   }

}
