Use SKs' solution, however, here's the easiest technic to remember (in terms of how it works):

String str = "";
for ( int i =0; i<charArray.length; i++ )
    str += charArray [i];

Don't use DrWarezz's solution.  For string contcationation, Java internally uses a String buffer.  So DrWarezz's solution will compile to approxamatly:
String str = "";
for ( int i =0; i<charArray.length; i++ ) {
    buff=new StringBuffer(str);
    buff.append(charArray [i]);
    str=buff.toString();
}


The String class is actually implemented internally as a character array. So use sudhakar_koundinya's answer.  When you use the
  String str =new String(charArray);
constructor.  The String class will copy your character array into its character array.
