Java 将整数调用为布尔值

代码中不起作用的部分

---

我需要将整数调用到该部分。此代码是我为编程类创建的游戏的主要部分，如有任何帮助，将不胜感激。

您需要“大于或等于”运算符：

=

if (bossHP >= 0){
    System.out.println("Congratulations you won!");
    break;
}
if (HP >= 0){
    System.out.println("Sorry you lost.");
    break;
}

---

好的，所以我不确定到底应该做什么，但我会尝试一下。看起来你有点糊涂了

例如：

    if (selection == 1){
        waits();
        System.out.println("You attack.");
        System.out.println(bossOneHP == bossOneHP - (OP - bossOneBP));
    }else if(selection == 2){

在这段代码中，您似乎在打印以控制变量bossOneHP和bossOneHP-（OP-bossOneBP）的比较，我认为这不是您想要的，因为只有当（OP-bossOneBP）为零（基本代数）时，语句才会打印为真。我怀疑你的意图是：

    if (selection == 1){
        waits();
        System.out.println("You attack.");
        bossOneHP = bossOneHP - (OP - bossOneBP);
    }else if(selection == 2){

这将变量bossOneHP设置为自身负（OP减去bossOneBP）。注意：您也可以这样做：

if (selection == 1){
        waits();
        System.out.println("You attack.");
        bossOneHP-= OP - bossOneBP;
    }else if(selection == 2){

哪个更快将一个值设置为自身减去以下值，而不是将其设置为新值的=。此外，如果它们相等，则==进行比较并返回true，而=将变量设置为新值

第二期：

if (bossHP == (0 || >0){

我假设如果bossHP小于或等于零，您希望激活if语句。| |语句是一个布尔运算符（它比较任意一侧的两个布尔输入，无论是变量、比较还是函数，如果其中一个输入为true，则返回单个布尔值true），其功能与单词或类似。要比较两个数字（在本例中为变量BOSHP和零），请使用几个运算符之一。详情如下:

==  -returns true (which activates the if statement) if the numbers or objects (if they are the same instance, not if they contain equal values) on both sides are identical. 

<  -returns true if the left hand number is smaller than the right hand one (doesn't work on objects)

>  -returns true if the right hand number is smaller

<= -returns true if the left hand number is smaller or equal to the right hand number

>= -returns true if the right hand number is smaller or equal to the left hand number

!= -returns true if the numbers or objects do not equal each other (effective opposite of the == token)

!  -only takes one boolean on the right hand side and returns its opposite (this inverts the value essentially), if(!val) is equivalent and better to if(val == false)

你也可以做while（真的）和break（休息）来代替while（继续播放）的事情；如果（boss>=0）输入3时的命令

{

是您需要的。有关比较运算符和相等运算符的详细信息，请参阅“要调用到节的整数”是什么意思？

==  -returns true (which activates the if statement) if the numbers or objects (if they are the same instance, not if they contain equal values) on both sides are identical. 

<  -returns true if the left hand number is smaller than the right hand one (doesn't work on objects)

>  -returns true if the right hand number is smaller

<= -returns true if the left hand number is smaller or equal to the right hand number

>= -returns true if the right hand number is smaller or equal to the left hand number

!= -returns true if the numbers or objects do not equal each other (effective opposite of the == token)

!  -only takes one boolean on the right hand side and returns its opposite (this inverts the value essentially), if(!val) is equivalent and better to if(val == false)

    if (bossHP >= 0){
        System.out.println("Congratulations you won!");
        break;
    }
