Easy way to reverse String

Question

Without going through the char sequence is there any way to reverse String in Java

Answer 1

Using minimal API support. A simple algorithm.

static String reverse(String str) {
    char[] buffer = str.toCharArray();
    for (int i = 0; i < buffer.length/2; ++i){
        char c = buffer[i];
        buffer[i] = buffer[buffer.length-1-i];
        buffer[buffer.length-1-i] = c;
    }
    return new String(buffer);
}
