生成mc启动器代码

以下是一个简单的Java代码示例，用于生成Minecraft启动器代码：

import java.io.FileWriter;
import java.io.IOException;

public class MinecraftLauncherCodeGenerator {
    
    public static void main(String[] args) {
        String username = "your_username";
        String version = "1.16.5";
        String gameDir = "path_to_game_directory";
        
        String code = generateLauncherCode(username, version, gameDir);
        
        try {
            FileWriter writer = new FileWriter("MinecraftLauncher.java");
            writer.write(code);
            writer.close();
            System.out.println("MinecraftLauncher.java generated successfully!");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public static String generateLauncherCode(String username, String version, String gameDir) {
        StringBuilder code = new StringBuilder();
        
        code.append("public class MinecraftLauncher {\n\n");
        
        code.append("    public static void main(String[] args) {\n");
        code.append("        String username = \"" + username + "\";\n");
        code.append("        String version = \"" + version + "\";\n");
        code.append("        String gameDir = \"" + gameDir + "\";\n\n");
        
        code.append("        System.out.println(\"Launching Minecraft...\");\n");
        code.append("        System.out.println(\"Username: \" + username);\n");
        code.append("        System.out.println(\"Version: \" + version);\n");
        code.append("        System.out.println(\"Game Directory: \" + gameDir);\n\n");
        
        code.append("        // Add your Minecraft launcher code here\n");
        
        code.append("    }\n");
        
        code.append("}");
        
        return code.toString();
    }
}

运行这段代码会生成一个名为MinecraftLauncher.java的文件，其中包含了一个main方法和几个变量，你可以在其中添加你自己的Minecraft启动器代码。请根据需要修改username，version和gameDir变量的值，并将你的Minecraft启动器代码添加到// Add your Minecraft launcher code here的注释行下方
