Can anyone help me how I can able to join the elements present in the array using a separator like "- ". So the output will be something like this:

"1 - 2 - 3 - 4 - 5 - 6 - 7"

Any help would be appreciated.

You can achieve this by using the StringUtils and ArrayUtils tool:

int[] arr = new int[] {1, 2, 3, 4, 5, 6, 7};

String result = StringUtils.join(ArrayUtils.toObject(arr), " - ");

Also, it can be work in any Java version starting from 1.2.

I hope this will help.
