如何通过顺序调用模拟的静态方法返回多个答案

public class MockStaticMethod {
    private static String[] answers = {"答案1", "答案2", "答案3"};
    private static int index = 0;

    public static String getNextAnswer() {
        if (index >= answers.length) {
            index = 0;  // 重置索引，循环返回答案
        }
        return answers[index++];
    }
}

String answer1 = MockStaticMethod.getNextAnswer();
String answer2 = MockStaticMethod.getNextAnswer();
String answer3 = MockStaticMethod.getNextAnswer();
