Select properties based on name and fetch the value

I have the below class with getters and setters.

class A{
 private String field1Required;
 private String field2Required;
 private String field3;
 private String field4;
}

Suppose in my main program I receive an object A populate as below,

field1Required = false; field2Required=true, field3=true; field4=false;

So I want select only the field1Required, field2Required and print the values of those properties. How can I achieve it using reflection or any other way?
