java - How to get my Java 'if' statement to work?

Question

I am very new to learning Java and currently I am working on a program that lets me fight the computer based on simple stats that I have assigned us and a random number to function as a dice roll. I recognize that there may be numerous other problems with my code, but the main issue I am trying to resolve is the "Syntax error on tokens, delete these tokens" on line 84 and the "Syntax error, insert "}" to complete Statement" on line 77.

I don't see what the issue is. What am I doing wrong? Both issues are listed near the bottom of my code in comments next to their corresponding lines.

import java.util.Scanner;
import java.util.Random;

public class Fight {

public static void main(String[] args) {
    Scanner keyboard = new Scanner(System.in);

    System.out.println("Enter your name");
        String you = keyboard.next();
        int youWounds = 1;
        int youTough = 4;
        int youAttack = 1;
        int youWS = 4;
        int youAS = 3;

        String Comp = "Bad Guy";
        int compWounds = 1;
        int compTough = 4;
        int compAttack = 1;
        int compWS = 4;
        int compAS = 3;

    System.out.println(you + ", do you want to FIGHT?!?!?");
    System.out.println("Yes / No?");

    String inputString = keyboard.next();       

    if (inputString.equalsIgnoreCase("Yes")) {
        System.out.println("FIGHT!!!!");
        while (youWounds > 0 && compWounds > 0) {

            int youRan = new Random().nextInt(6)+1; // this is where you roll to hit 
            System.out.println(you + " rolls " + youRan +" to hit");

            if (youRan >= 7-youWS) { // this is the logic for roll to hit 
                System.out.println(you +" hit");

                int youRanTW = new Random().nextInt(6)+1; // this is where you check to see if your hit wounds 
                System.out.println(you + " rolls " + youRanTW +" to wound");
                if (youRanTW > compTough) { // this is the logic for roll to wound
                    System.out.println(you+" wounds"+Comp);

您的程序流程存在一些问题，但当前的问题是您正试图else在while循环中使用。这是不可能或没有必要的。

循环将while继续，直到满足定义的条件。一旦发生这种情况，while循环结束并执行下一行代码。

因此，从循环else {的关闭中删除。while然后，您可以只评估结果。

这是更正后的代码，并带有一些注释以显示删除内容的位置：

        int youWounds = 1;
