in java, a method can only return a single value. however, there are several ways to effectively return multiple values from a method. below are some common approaches, along with code examples for each approach.

1. using an array
you can return an array of values if the types are the same.



2. using a class or a record
you can create a custom class or use a java record (introduced in java 14 as a preview feature and finalized in java 16) to hold multiple return values.

#### using a class:


#### using a record:


3. using a map
if you're returning values of different types or don't want to create a new class, you can use a `map` to return multiple values.



4. using a list of objects
if you want to return multiple values of different types, you can create a list of objects.



conclusion
java does not support returning multiple values directly like some other languages. however, by using arrays, classes, records, maps, or lists, you can effectively return multiple values from a method. the choice of method depends on your specific use case, including the types and the number of values you need to return.
