java中实现用for循环动态创建变量或动态调用方法

在网上找了好久，好像没有很好的方法。看来以后的开发要尝试动态语言了。
折中的办法如下：

/**

 */
public class Test {
    private String answer1 = "1";
    private String answer2 = "2";
    private String answer3 = "3";
    
    public static void main(String[] args) {
        Test test = new Test();
        for (int i = 0; i < 3; i++) {
            String answer = "";
            switch(i) {
                case 1 : answer = test.getAnswer1(); break;
                case 2 : answer = test.getAnswer2(); break;
                case 3 : answer = test.getAnswer3(); break;
                default : answer = "";
            }
            System.out.println("answer" + i + " : " + answer);
        }
    }

    public String getAnswer1() {
        return answer1;
    }

    public void setAnswer1(String answer1) {
        this.answer1 = answer1;
    }

    public String getAnswer2() {
        return answer2;
    }

    public void setAnswer2(String answer2) {
        this.answer2 = answer2;
    }

    public String getAnswer3() {
        return answer3;
    }

    public void setAnswer3(String answer3) {
        this.answer3 = answer3;
    }

}

晕。动态变量要不用数组替代 要不用反射。哪是这样

这是动态创建变量吗？

那如果要动态创建10，000个变量呢？
