使用Java实现在线考试系统的多语言支持功能

Locale locale = new Locale("zh", "CN"); // 设置当前语言为中文
ResourceBundle resourceBundle = ResourceBundle.getBundle("语言代码", locale);
String translation = resourceBundle.getString("key"); // 获取翻译内容

Locale locale = new Locale("en", "US"); // 切换语言为英文
ResourceBundle resourceBundle = ResourceBundle.getBundle("语言代码", locale);
// 刷新界面显示

import java.util.Locale;
import java.util.ResourceBundle;

public class ExamSystem {
    private ResourceBundle resourceBundle;

    public ExamSystem(Locale locale) {
        resourceBundle = ResourceBundle.getBundle("语言代码", locale);
    }

    public String getTranslation(String key) {
        return resourceBundle.getString(key);
    }

    public static void main(String[] args) {
        Locale locale = new Locale("zh", "CN"); // 默认语言为中文
        ExamSystem examSystem = new ExamSystem(locale);

        String loginButton = examSystem.getTranslation("login_button");
        System.out.println(loginButton); // 输出：登录

        // 用户切换语言为英文
        locale = new Locale("en", "US");
        examSystem = new ExamSystem(locale);

        loginButton = examSystem.getTranslation("login_button");
        System.out.println(loginButton); // 输出：Login
    }
}
