Here is java sample code for swapping java chars recursively.. You can get full sample code at http://java2novice.com/java-interview-programs/string-reverse-recursive/

public String reverseString(String str){

    if(str.length() == 1){
        return str;
    } else {
        reverse += str.charAt(str.length()-1)
                +reverseString(str.substring(0,str.length()-1));
        return reverse;
    }
}
