Returning Multiple values in Java
Java doesn’t support multi-value returns. We can use following solutions to return multiple values.
If all returned elements are of same type
We can return an array in Java. Below is a Java program to demonstrate the same.
Sum = 150 Sub = 50
If returned elements are of different types
Using Pair (If there are only two returned values)
We can use Pair in Java to return two values.
If there are more than two returned values
We can encapsulate all returned types into a class and then return an object of that class.
Let us have a look at the following code.
Multiplication = 200 Division = 0.5 Addition = 30
Returning list of Object Class
