I am a beginner level java student. So my question might be very easy for you guys. I am just wondering if it is possible to return multiple values in a single program?

If it is possible, can you guys tell me the process, please?

Yes, in java you can return multiple values in a single program. Though it depends on how and what kind of data are you wanting to return. As per your sayings, I am showing you the way to do it for the same data-type by returning an array.

class Test { 

    static int[] getSumAndSub(int a, int b) 
        int[] ans = new int[2]; 
        ans[0] = a + b; 
        ans[1] = a - b; 
        return ans; 
    public static void main(String[] args) 
        int[] ans = getSumAndSub(20, 10); 
        System.out.println("Sum = " + ans[0]); 
        System.out.println("Sub = " + ans[1]); 


Sum = 30
Sub = 10

If you want to return a different type of data in a single program you can use the object class like below:

import java.util.*; 
class Test { 
    public static List<Object> getDetails() 
        String name = "Name"; 
        int age = 25; 
        char gender = 'M'; 
        return Arrays.asList(name, age, gender); 
    public static void main(String[] args) 
        List<Object> person = getDetails(); 

In this case, the output will be:

[Name, 25, M]
