Using Java 8 you can do this very neatly and easily with:

String.join(delimiter, elements);

This works in three ways:

1) Specifying the elements directly

String joined1 = String.join(",", "a", "b", "c");

2) Using array’s

String[] array = new String[] { "a", "b", "c" };
String joined2 = String.join(",", array);

3) Using iterables

List<String> list = Arrays.asList(array);
String joined3 = String.join(",", list);

If you need for android:

String android.text.TextUtils.join(CharSequence delimiter, Object[] tokens)

Example:

String joined = TextUtils.join(";", MyStringArray);
