java - 我的代码有什么问题(初学者)(Java)

Question

我正在做一些 Java 只是为了练习，并决定做一个龙与地下城类型的代码。 (这只是角色统计数据的滚动)

我输入了所有内容，它一直说(角色)最大的统计数据是活力。帮忙？

import java.util.Random;
import java.util.Scanner;
public class DAndD {

    public static void main(String[] args) {
         // TODO Auto-generated method stub
        Scanner input = new Scanner(System.in);
        Random generator = new Random();
        System.out.println("Choose a name for your Dungeons & Dragons       character.");
        String character = input.next();
        System.out.print("Ah, " + character + " has a nice ring to  it.\nLet's roll for stats shall we?");
        int str = generator.nextInt(21);
        int dex = generator.nextInt(21);
        int intel = generator.nextInt(21);
        int wis = generator.nextInt(21);
        int vit = generator.nextInt(21);

        if (str > 0);
        String trait = "strength";
        int large = str;
        if (dex > large);
        trait = "dexterity";
        large = dex;
        if (intel > large);
        trait = "intelligence";
        large = intel;
        if (wis > large);
        trait = "wisdom";
        large = wis;
        if (vit > large);
        trait = "vitality";
        large = vit;


        if(large == str){
        System.out.println("\n" + character + "'s best stat is its strength!");
        }
        else if (large == dex){
        System.out.println("\n" + character + "'s best stat is its dexterity!");
        }
        else if (large == intel){
        System.out.println("\n" + character + "'s best stat is its intelligence!");
        }
        else if (large == wis){
        System.out.println("\n" + character + "'s best stat is its wisdom!");
        }
        else if (large == vit){
        System.out.println("\n" + character + "'s best stat is its vitality");
        }
        System.out.println("\nStrength: " + str + "\nDexterity:" + dex + "\nIntelligence: " + intel + "\nWisdom: " + wis + "\nVitality: " + vit);

        }
}

所以，这就是目前的最终结果:

输出

Choose a name for your Dungeons & Dragons character.

*Toetar*

Ah, Toetar has a nice ring to it.

Let's roll for stats shall we?

Toetar's best stat is its vitality

Strength: 5

Dexterity: 19

Intelligence: 1

Wisdom: 6

Vitality: 4

Answer 1

if 语句后有分号 (;) (if (vit > large);)，这会否定它们的功能。这就是为什么使用 {...}

很重要

我“假设”你的意思更像是......

String trait = "";
int large = -1;
if (str > 0) {
    trait = "strength";
    large = str;
} else if (dex > large) {
    trait = "dexterity";
    large = dex;
} else if (intel > large) {
    trait = "intelligence";
    large = intel;
} else if (wis > large) {
    trait = "wisdom";
    large = wis;
} else if (vit > large) {
    trait = "vitality";
    large = vit;
}
