I am new to Java.

Coming from Python, I find it way more tedious to deal with arrays in Java than Python.
Specifically, to access arrays' positions. This is the Python code I want to translate to Java:

# Access first 3 elements

arr = [1, 2, 3, 4, 5]
arr[:3]

output: [1, 2, 3]

But in Java, there is no "colon", and the shortest way I have found to get the first three elements is throuh a loop.

Is there a package or a non-loop way to do this?

  • Yes, exactly! But, when I try to print it out to the console... it returns "[I@e9e54c2" instead. How's that? Commented Aug 31, 2021 at 13:55

    Something like System.out.println(java.util.Arrays.toString(subarray)); should do the trick. Commented Aug 31, 2021 at 13:56
  • Just note that arrays are objects to and thus if you call System.out.println(array) it will call toString() on the array which returns the result. Arrays.toString(array) basically iterates over the array, calls toString() on each element and returns a list of those strings which are separated by a comma. Commented Aug 31, 2021 at 13:58
  • You can do it in a functional style like that String[] a = {"str1","str2"}; Arrays.stream(a).limit(3).forEach(System.out::println); Commented Aug 31, 2021 at 15:04
