Java Reflection - Get Current Field Value in Existing Object

I have a constructed object of the type below,

public class Form {
   private String a;
   private String b;
   private Boolean c;

   public String getA() { return a; }
   public void setA (String a) { this.a = a; }
   public String getB() { return b; }
   public void setB (String b) { this.b = b; }
   public Boolean getC() { return c; }
   public void setC (Boolean c) { this.c = c; }
}

I'm using reflection to examine an existing object, e.g. this Form: ("testA", "testB", False)

How do I get the current value of a particular field, let's say String b ?

// Assume "form" is my current Form object
Field[] formFields = form.getClass().getDeclaredFields();
if (formFields != null) {
   for (Field formField : formFields) { 
       Class type = formField.getType();
       // how do I get the current value in this current object?
   }
}
