我对代码中的 while 循环有疑问

Question

当它变为零时，如何通过使用 playerHP 强制停止 while 循环？有时我会在它周围放置一个 If 语句，但它不起作用。编码新手，因此提供一些提示也很酷。:)public class RPGFight {public static void main (String args[]) {    int playerHP = 30;    int boss1HP = 420;    int exp = 0;    System.out.println("You open the chamber door to see what lies beyond.");    System.out.println("A demogorgon jumps out and attacks!");    System.out.println("You deftly pull out your mighty blade and defend youself");    while (boss1HP > 0) {        if (boss1HP > 0) {            int hit1 = (int)(Math.random()*20);            int hit2 = (int)(Math.random()*20);            int hit3 = (int)(Math.random()*20);            int hit4 = (int)(Math.random()*20);            int hit5 = (int)(Math.random()*20);            int hit6 = (int)(Math.random()*20);            int bossDMG = (int)(Math.random()*5);            System.out.println("\nYou hit the demogorgon for " + hit1 + " points of damage");            System.out.println("You hit the demogorgon for " + hit2 + " points of damage");            System.out.println("You hit the demogorgon for " + hit3 + " points of damage");            System.out.println("You hit the demogorgon for " + hit4 + " points of damage");            System.out.println("You hit the demogorgon for " + hit5 + " points of damage");            System.out.println("You hit the demogorgon for " + hit6 + " points of damage");            System.out.println("You have been hit for " + bossDMG + " points of damage");            playerHP -= bossDMG;            boss1HP -= hit1+hit2+hit3+hit4+hit5+hit6;        }         if (boss1HP < 0) {            int expbattle = (int)(Math.random()*126+5);            exp += expbattle;            System.out.println("\nThe demogorgon falls to the floor, lifeless.");            System.out.println("Congratulations! You earned " + expbattle + " points of experience.");        }    }}}

Answer 1

通过break在修改playerHP后立即添加一个小于或等于零的检查后。喜欢，

playerHP -= bossDMG;

if (playerHP <= 0) {

    break;

}

// ...

Answer 2

将 if 条件放在 playerHP -= bossDMG 之后；

如果（玩家HP < 1）中断；

当 playerHP 值小于等于 0 时，这将中断 while 循环。
