Java 的反射机制如何将属性名的字符串转成对应属性

[q505507538]

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

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