Java Reflection: How to get the name of a variable?

Question

Using Java Reflection, is it possible to get the name of a local variable? For example, if I have this:

Foo b = new Foo();
Foo a = new Foo();
Foo r = new Fo         


        

Answer 1

You can do like this:

Field[] fields = YourClass.class.getDeclaredFields();
//gives no of fields
System.out.println(fields.length);         
for (Field field : fields) {
    //gives the names of the fields
    System.out.println(field.getName());   
}
