Get all attributes easy way

Question

is it possible to get the values of all attributes of an object without creating a getter method one by one for each attribute? i mean a car object in Vehicle class has name, speed, color, and i would like to get all information at once about this car. Sorry for bad english.

Answer 1

You can create getter for all data of similar type you need and return it in array. Alternatively you can use Object[] array as result of getter and return all data independent of type but it is a bad practice, i do not recommend to code like that.

Answer 2

public class Soldier {
String name;
String rank;

Soldier() {
name = "Hartman";
rank = "Gunnery Sergeant";
}

String[] getRankAndName() {
String[] result = new String[2];
result[0] = rank;
result[1] = name;

return result;
}

public static void main(String[] args) {
Soldier s = new Soldier();

String[] text = s.getRankAndName(); //we get name and rank (two attributes) with one method

System.out.println(text[0] + " " + text[1]); //outputs "Gunnery Sergeant Hartman"
}
}
