java - feed方法java if语句

Question

decHungry() 将饥饿减少 10，incEnergy() 将能量增加 10。我想确保饥饿水平不会超过 0 至负数数字且能量水平不超过 100。我怎么做？

protected void feed() {
    System.out.println("\nEating..."); 
    if (hungry <= 90 && hungry >= 0) {
        decHungry();
        incEnergy();
        System.out.println("I've just ate dumplings, my current energy state is " + energy + " and hungry state is " + hungry);
    }
    else { 
        System.out.println ("I have ate enough!"); 
    }
}

Answer 1

在调用该函数之前，您需要确保饥饿值大于或等于 10，并且能量小于或等于 90。

if(hungry >= 10){
    decHungry();
}
if(energy <=90){
    incEnergy();
}
