reflection - Getting a property/field name using getter method of a pojo/java bean?

Question

I have a below class and i need to get field name from getter method using java reflection. Is it possible to get field name or property name using getter method?

class A {

    private String name;
    private String salary;

    // getter and setter methods
}

My questions is: can i get field/property name by getter method? If I use getName(), can I get name property? I need name property but not its value. Is it possible through java reflection?

Answer 1

yes it's 100% possible..

public static String getFieldName(Method method)
{
    try
    {
        Class<?> clazz=method.getDeclaringClass();
        BeanInfo info = Introspector.getBeanInfo(clazz);  
        PropertyDescriptor[] props = info.getPropertyDescriptors();  
        for (PropertyDescriptor pd : props) 
        {  
            if(method.equals(pd.getWriteMethod()) || method.equals(pd.getReadMethod()))
            {
                System.out.println(pd.getDisplayName());
                return pd.getName();
            }
        }
    }
    catch (IntrospectionException e) 
    {
        e.printStackTrace();
    }
    catch (Exception e) 
    {
        e.printStackTrace();
    }


    return null;
}
