How to transform a Java String into a Java Array Object?

On a . jsp page, I have the following code:

String[] arrayRegioes = request.getParameterValues("numRegiaoUsuario");//objeto

When I print the arrayRegioes, the value shown is:

[Ljava.lang.String;@5a879b45

Now, I need to turn a string that was made in the hand:

[55826586566, 54555555454, 994139792]

On an object array, as the format of that informed above.

    System.out.println(Arrays.toString(arrayRegioes)) will print the array correctly (i.e., will print the list of elements instead of [Ljava.lang.String;@5a879b45).

  • Int or String array?

You could try wearing something like that. PS: I didn’t test it, it’s just something I remember from college.

String[] array = values.split(",");

If there can be a string with null values, you must use a second parameter, following example.

String[] array = values.split("\\|", -1);

    In the case of OP it will probably have to remove the first and last characters too ([, ]), this can be done with substring or replace.

  • To create the array, I have to remove the brackets from the string ?
