Question

public String[] decode(String message)
{
     String ans1 = "hey"; 
     String ans2 = "hi";  
     return {ans1 , ans2};  // Is it correct?
}

This above example does not work properly. I am getting a error.

How can I achieve the initial question?

Answer 1

The correct syntax would be

 return new String[]{ ans1, ans2 };

Even though you’ve created two Strings (ans1 and ans2) you haven’t created the String array (or String[]) you’re trying to return. The syntax shown above is shorthand for the slightly more verbose yet equivalent code:

String[] arr = new String[2];
arr[0] = ans1;
arr[1] = ans2;
return arr;

where we create a length 2 String array, assign the first value to ans1 and the second to ans2 and then return that array.
