Question

In Java, I want to delete certain elements from a char array so it does something like:

char[] Array1 = {'h','m','l','e','l','l'};
Array1 = //character index[2] to character index[5]

How can this be done?

Answer 1

In Java you can’t delete elements from an array. But you can either:

Create a new char[] copying only the elements you want to keep; for this you could use System.arraycopy() or even simplerArrays.copyOfRange(). For example, for copying only the first three characters of an array:

char[] array1 = {'h','m','l','e','l','l'};
char[] array2 = Arrays.copyOfRange(array1, 0, 3);

Or use a List<Character>, which allows you to obtain a sublist with a range of elements:

List<Character> list1 = Arrays.asList('h','m','l','e','l','l');
List<Character> list2 = list1.subList(0, 3);
