Simple solution is   public String frontBack String str      if  str    null    str length      0        return str        char   cs   str toCharArray      char first   cs 0     cs 0    cs cs length -1     cs cs length -1    first    return new String cs       Using a character array  watch out for the nasty empty String or null String argument    Another solution uses StringBuilder  which is usually used to do String manupilation since String itself is immutable   public String frontBack String str      if  str    null    str length      0        return str        StringBuilder sb   new StringBuilder str       char first   sb charAt 0     sb setCharAt 0  sb charAt sb length  -1      sb setCharAt sb length  -1  first     return sb toString        Yet another approach  more for instruction than actual use  is this one   public String frontBack String str      if  str    null    str length    lt  2        return str        StringBuilder sb   new StringBuilder str     String sub   sb substring 1  sb length   -1     return sb reverse   replace 1  sb length   -1  sub  toString        Here the complete string is reversed and then the part that should not be reversed is replaced with the substring
