Given a string, take the first 2 chars and return the string with the 2 chars added at both the front and back, so "kitten" yields"kikittenki". If the string length is less than 2, use whatever chars are there.

front22.java

public class Test {
    public static void main(String[] args) {
        System.out.println(method("hi"));
    }

    public static String method(String str){
        if (str.length()<2)
            return str+str+str;
        String s=str.substring(0,2);
        return s+str+s;
    }
}
