Random Selection from Random List of Strings (JAVA)
问题
我有非常有限的编程经验，正在尝试为我和我的朋友在《使命召唤：战区》中创建一个随机职业生成器，只是为了好玩。这是一个非常基本的生成器，但我遇到了一些问题，无法得到我想要的输出。它变成了一个比我预期的项目更大的项目，所以我会接受任何帮助！
对于那些没有玩过这个游戏的人来说，最多可以选择9种不同的附件类别（如消音器、枪管、光学镜、枪托等），但只能装备最多5个，这意味着某些附件类别将不会被使用。由于我正在尝试先解决基本问题，所以我还没有添加所有的附件类别或特殊附件。
我希望最终的输出类似于：
主武器：M4A1主武器握把：Commando主武器激光：无主武器枪托：无枪托附件主武器弹夹：50发主武器后握把：Stippled主武器枪管：大枪管
目前，它只会输出类似于：
主武器：M4A1 主要附件：Commando 无 无枪托附件 50发 Stippled 无
这是我目前的代码（如果代码看起来不好，请谅解lol）：
import java.util.concurrent.ThreadLocalRandom;public class RandomClass {public static void main(String[] args) {System.out.println("主武器：" + randomPrimaryGun());System.out.println("主要附件：" + primaryAttachments());System.out.println("副武器：" + randomSecondaryGun());}public static String randomPrimaryGun() {String[] primaryGuns = {"M4A1", "Kilo", "Grau", "Bruen", "FAL", "M13"};int randIdx = ThreadLocalRandom.current().nextInt(primaryGuns.length);String randPrimary = primaryGuns[randIdx];return randPrimary;}public static String randomSecondaryGun() {String[] secondaryGuns = {"MP5", "P90", "AUG", "Uzi", "MP7"};int randIdx = ThreadLocalRandom.current().nextInt(secondaryGuns.length);String randSecondary = secondaryGuns[randIdx];return randSecondary;}public static String primaryAttachments() {String[] primaryGrip = {"Merc", "Ranger", "Commando", "None"};String[] primaryLaser = {"Tac", "5mw", "None"};String[] primaryStock = {"无枪托附件", "无枪托", "快速枪托"};String[] primaryMag = {"50发", "60发"};String[] primaryRearGrip = {"Stippled", "None"};String[] primaryBarrel = {"大枪管", "短枪管"};int randIdx0 = ThreadLocalRandom.current().nextInt(primaryGrip.length);int randIdx1 = ThreadLocalRandom.current().nextInt(primaryLaser.length);int randIdx2 = ThreadLocalRandom.current().nextInt(primaryStock.length);int randIdx3 = ThreadLocalRandom.current().nextInt(primaryMag.length);int randIdx4 = ThreadLocalRandom.current().nextInt(primaryRearGrip.length);int randIdx5 = ThreadLocalRandom.current().nextInt(primaryBarrel.length);String grip = primaryGrip[randIdx0];String laser = primaryLaser[randIdx1];String stock = primaryStock[randIdx2];String mag = primaryMag[randIdx3];String rearGrip = primaryRearGrip[randIdx4];String barrel = primaryBarrel[randIdx5];// 在此处构建你的输出字符串}}
我知道我需要一些if/else语句，也许需要一些循环，但我不知道如何在从列表中随机选择的情况下实现它。如果有人能帮我入门，我将不胜感激！一旦我知道了基本方法，我就可以从那里开始，并添加我需要的任何其他内容！
我还没有开始处理副武器附件，因为我无法弄清楚如何处理主要附件，但实质上它会是相同的代码，只是有一些不同。
谢谢！

I have very minimal experience programming and I'm trying to create a random(ish) class generator for my buddies and I on Warzone for fun. It's a very basic generator but I'm having some trouble figuring out how to get the outputs I want. It turned into a bigger project than I anticipated so I'll take any help I can get!
For anyone who hasn't played the game, there are at most 9 different classes of attachments you can choose from (i.e. suppressors, barrels, optics, stocks, etc) but you can only have a maximum of 5 equipped, meaning some attachment classes won't be used. I haven't added all the attachment categories or special attachments there might be since I'm trying to work out the basics first.
I'd like to have the final output be something like:
Primary Gun: M4A1Primary Grip: CommandoPrimary Laser: NonePrimary Stock: No Stock AttachmentPrimary Mag: 50Primary Rear Grip: StippledPrimary Barrel: Big Barrel
As of now it just outputs something like
Primary Gun: M4A1 Primary Attachments: Commando None No Stock Attachment 50 Stippled None
This is what I have so far (excuse if the code looks ugly lol)
import java.util.concurrent.ThreadLocalRandom;public class RandomClass {public static void main(String[] args) {System.out.println("Primary: " + randomPrimaryGun());System.out.println("Attachments: " + primaryAttachments());System.out.println("Secondary: " + randomSecondaryGun());}public static String randomPrimaryGun() {String[] primaryGuns = {"M4A1", "Kilo", "Grau", "Bruen", "FAL", "M13"};int randIdx = ThreadLocalRandom.current().nextInt(primaryGuns.length);String randPrimary = primaryGuns[randIdx];return randPrimary;}public static String randomSecondaryGun() {String[] secondaryGuns = {"MP5", "P90", "AUG", "Uzi", "MP7"};int randIdx = ThreadLocalRandom.current().nextInt(secondaryGuns.length);String randSecondary = secondaryGuns[randIdx];return randSecondary;}public static String primaryAttachments() {String[] primaryGrip = {"Merc ", "Ranger ", "Commando ", "None "};String[] primaryLaser = {"Tac ", "5mw ", "None "};String[] primaryStock = {"No Stock Attachment ", "No Stock ", "Fast stock "};String[] primaryMag = {"50 ", "60 "};String[] primaryRearGrip = {"Stippled ", "None "};String[] primaryBarrel = {"Big Barrel", "Short Barrel"};int randIdx0 = ThreadLocalRandom.current().nextInt(primaryGrip.length);int randIdx1 = ThreadLocalRandom.current().nextInt(primaryLaser.length);int randIdx2 = ThreadLocalRandom.current().nextInt(primaryStock.length);int randIdx3 = ThreadLocalRandom.current().nextInt(primaryMag.length);int randIdx4 = ThreadLocalRandom.current().nextInt(primaryRearGrip.length);int randIdx5 = ThreadLocalRandom.current().nextInt(primaryBarrel.length);String grip = primaryGrip[randIdx0];String laser = primaryLaser[randIdx1];String stock = primaryStock[randIdx2];String mag = primaryMag[randIdx3];String rearGrip = primaryRearGrip[randIdx4];String barell = primaryBarrel[randIdx5];}}
I know I need some if/else statements and maybe some loops but I have no idea how to implement that with a random selection from a list. If anyone could at least help me get started I'd really appreciate it! Once I know the basic method I can go from there and add whatever else I need to!
I haven't bothered starting with the secondary attachments yet since I can't figure out how to do the primary attachments yet, but it'd essentially be the same code just with a few differences.
Thanks you!

这是如何从列表中选择一个随机元素的方法：
List<String> myList = new ArrayList<>();myList.add("M4A1");myList.add("Kilo");myList.add("Grau");int randomIndex = ThreadLocalRandom.current().nextInt(myList.size());String randomGun = myList.get(randomIndex);
randomGun 的值将是这三支枪中的一个。
编辑：
要随机选择一个列表，你可以创建一个列表的 Map：
Map<Integer, List<String>> myMap = new HashMap<>();myMap.put(1, Arrays.asList("M4A1", "Kilo", "Grau"));myMap.put(2, Arrays.asList("Merc", "Ranger", "Commando"));myMap.put(3, Arrays.asList("50", "60", "70"));int randomIndex = ThreadLocalRandom.current().nextInt(myMap.size());List<String> randomList = myMap.get(randomIndex);
对于一个简单的项目来说，这是可以的，但如果你计划扩展这个项目，我建议使用类。
英文:
This is how to select a random element in a list:
List<String> myList = new ArrayList<>();myList.add("M4A1");myList.add("Kilo");myList.add("Grau");int randomIndex = ThreadLocalRandom.current().nextInt(myList.size());String randomGun = myList.get(randomIndex);
The value of randomGun will be one of the three guns.
Edit:
To choose randomly a list you can create a Map of lists:
Map<Integer, List<String>> myMap = new HashMap<>();myMap.put(1, Arrays.asList("M4A1","Kilo","Grau"));myMap.put(2, Arrays.asList("Merc","Ranger","Commando"));myMap.put(3, Arrays.asList("50","60","70"));int randomIndex = ThreadLocalRandom.current().nextInt(myMap.size());List<String> randomList = myMap.get(randomIndex);
For a simple project is OK, but if you plan to extend this project then I recommend to use classes.

Sure, here's the translation:
这可以通过将您的值存储在一个可以通过索引访问的集合中来实现，就像您在数组中所做的那样。然后，生成一个介于 0 和最高索引之间的随机整数。从该索引处的集合中取出值。即可。
英文:
This could be achieved by storing your values in a collection that can be accessed by index, as you are doing with your array. Then you generate a random integer between 0 and your highest index. Take the value from the collection at that index. Voila.
