如何将类的字段名称作为参数传递到字符串中？
我想知道如何将类的字段名称作为参数传递到字符串中？
例如，假设我与此成员有一个A类A：
public class A {
String name;
String reference;
....
}
我想要的是能够初始化具有参数的字符串 两个Classe字段名称之一，可以动态显示。因此，例如，我想这样做：
System.out.println("the field {nameField} belong to class A.");
在输出中，我会有这样的：
output : the field name belong to class A.
在Java中可以吗？
有什么帮助会不胜感激吗？

I'm wondering How can I pass field name of a class as parameter to include it in a String?
For example, let's say I have a class A with this members :
public class A {
String name;
String reference;
....
}
What I want, is to be able to initialize a string having as parameters
one of the two classe field name to display it dynamically. So for instance, I want to do this :
System.out.println("the field {nameField} belong to class A.");
And in output I would have this :
output : the field name belong to class A.
Is that possible in Java ?
Any help would be much appreciated ?

这可以通过在Java中使用反射来完成。

This can be done by use of reflection in Java.
