Get list of attributes of an object in an List

Question

When there is an List, is there a possibility of getting List of all person.getName() out of that? Is there an prepared call for that

Answer 1

Not tested but this is the idea:

public static  List getAttributeList(List list, Class clazz, String  attribute)    
{
    List attrList= new ArrayList();

    attribute = attribute.charAt(0).toUpperCase() + attribute.substring(1); 
    String methodName = "get"+attribute;

    for(Object obj: personList){
        T aux = (T)clazz.getDeclaredMethod(methodName, new Class[0]).invoke(obj, new Object[0]);
        attrList.add(aux);
    }
}
