    public class test {

    private String string_1 = "aaaa";
    private String string_2 = "bbbb";
    private String string_3 = "cccc";
    private String string_4 = "dddd";
    private String string_5 = "eeee";

    public static void main(String[] args) {
    for(int i=1; i < 6; i++){
    String str = "string_" + i;
    System.out.println(str);
    }
    }
    }

    很明显这个输出结果是
    string_1
    string_2
    string_3
    string_4
    string_5
    可是我想要得到的是
    aaaa
    bbbb
    cccc
    dddd
    eeee
    应该如何实现
  • string
  • private
  • eeee

    System.out.println(test.class.getDeclaredField(str).get(new test()))
