method to return array elements public static int readArray int arr 10,20,30,40 return arr Let us assume we have an array of integer int data type arr 10,20,30,40 and we want to return it from the method. Then the return type should be int, because it is an array of int data types. Similarly, if it is an array of double
The return type is declared as int and we return the reference to the locally constructed 2D array. You can visualize this structure Higher dimensional arrays work the same way - just declare the method return type accordingly. Returning Arrays of Objects in Java. In Java, arrays can also contain object references.
In Java, there are several ways to return an array from a method, each offering its own advantages and use cases.
