Useful ways to working with Strings in Java

•  When  we want to  print a  array  , We can use this  way

             String text  = "abcaada";
             System.out.println( Arrays.toString(  text .split("a") )  );

             The string you give  split  defines a regular expression, so any characters special in regular 
             expressions have to be   escaped:

       String[] parts = string.split("\\$@");

• When we want to convert   List <String>   stringListValues    , to  string value  . We can use following way
  

            String commaSeperatedStringListValues    =  String.join(  "','"    ,    stringListValues    ) ;

• When we have string  values set such as   String   names  =  "Saman , Kumara , Ramanayaka "   ;     and  we  want 

            to  separate that  string values from " , " and put into  a  array , we  can use

           String[]  nameArray  =   names.split( " , " ); 

• String newStringValue = String.join(  "-> ", "Wake up", "Eat", "Play", "Sleep", "Wake up"  );

           System.out.println(  newStringValue );
   
         Output will be :   Wake up-> Eat-> Play-> Sleep-> Wake up

• To reverse a string
  
  String  stringObj=  "Hiiiiii  Kamlal";
  StringBuffer  stringBufferObj =  new  StringBuffer( stringObj );
  
  stringBufferObj.reverse();
