Is there any way to create a dynamic class based on list of strings of variable names in java?

I have a list of variables names (which I will fetch from Database) as:

List<String> variableNames= ["name", "age", "gender"];

and these variable names will be dynamic based on table data in database.

Now, I want to be able to create a dynamic class out of these variables, like:

public class PersonDTO{

private String name;
private String age;
private String gender;

//getter and setters

}

Is there anyway, I can do this in java?

You can use Map<String, Object> where DB column is key and the column data is the value of map.

Map<String, Object> PersonDTO = new Hashmap<>();

map.put("age", new Integer());
map.put("name", new String());

String name = (String)map.get("name");

Java does not have a way of creating dynamic variables.
You need to declare variable in your code itself.
You could instead use a map in some way to achieve your goals. 

Map<String,String> map = new HashMap<String,String>();
map.put("name","value");
...
