How to realize word-guessing Mini Game by Java

This article will explain in detail how to achieve word-guessing Mini Game with Java. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Train of thought

Syntax fundamentals: StringBuilder is similar to a list and can change elements.

Package Practice;public class tt {public static void main (String [] args) {String str = "banana"; System.out.println (str.indexOf ('z')); / /-1 System.out.println (str.indexOf ('ajar, 2)); / / 3 StringBuilder words = new StringBuilder (); for (int I = 0; I

< 5; i++) words.append('*'); // "*****" System.out.println(words.length()); // 5 System.out.println(words.indexOf("a"));// -1 System.out.println(words.indexOf("*", 1)); // 1 words.setCharAt(3, 'a'); // "***a*" System.out.println(words); }}代码package Practice;import java.util.Scanner;public class Guess { public static String words[] = {"banana", "telecommunication", "programming", "bupt"}; public static boolean[] guessed = new boolean[words.length]; // 判断猜过 public static int num_guessed = 0; // 猜过的单词数量 public static char keep; // 是否继续y or n public static void main(String[] args) {// for(int i = 0; i < guessed.length; i ++ ) System.out.println(guessed[i]); Scanner scanner = new Scanner(System.in); do{ // 随机产生要猜测的单词 ans int index = (int) (Math.random() * words.length); String ans = words[index]; // 再来一次时的重复检测 while(guessed[index] == true) { index = (int) (Math.random() * words.length); ans = words[index]; } // 初始化，StringBuilder类似list StringBuilder guessedWord = new StringBuilder(); for (int i = 0; i < ans.length(); i++) guessedWord.append('*'); int numberOfCorrectLettersGuessed = 0, numberOfMisses = 0; // 模拟过程 while (numberOfCorrectLettersGuessed < ans.length()) { System.out.print("(Guess) Enter a letter in word " + guessedWord + " >

"); String s = scanner.nextLine (); char letter = s.charAt (0); if (guessedWord.indexOf (letter +") > = 0) {/ / correct guess, but repeated, not counting the number of errors System.out.println ("" + letter + "is already in the word");} else if (ans.indexOf (letter))

< 0) { // 猜错 System.out.println(" " + letter + " is not in the word"); numberOfMisses++; } else { // 猜中，进行标记与赋值 int k = ans.indexOf(letter); while (k >
