Add String to beginning of String array

Question

Is it possible to add a string to beginning of String array without iterating the entire array.

Answer 1

You can do some thing like below

public class Test {

public static String[] addFirst(String s[], String e) {
    String[] temp = new String[s.length + 1];
    temp[0] = e;
    System.arraycopy(s, 0, temp, 1, s.length);
    return temp;
}

public static void main(String[] args) {
    String[] s = { "b", "c" };
    s = addFirst(s, "a");
    System.out.println(Arrays.toString(s));
}
}
