Hi!

It's very easy
1) If you need to return a values of the same type then you should use an array.

public String[] getSomthing() {
String[] s = new String[2];
s[0] = "test1";
s[1] = "test2";
return s;
}

2) If you need to return a values of the different types then you should use a value object.

public class CustomVO {
private String val1;
private int val2;
// Add get/set methods
}

public CustomVO getSomthing() {
CustomVO vo = new CustomVO();
vo.setVal1("test");
vo.setVal2(10);
return vo;
}

3) Also you can use a subclasses of a List, Map or Set interfaces.
public List getSomething() {
List list = new ArrayList();
list.add("test1");
list.add("test2");
return list;
}
