String Array Split

String s = "HELLO Java, JAVA IS INDEPENDENT. jAvA";

Here we can change all word JAVA to upper case by splitting it. 

    String[] s2 = s.split(" ");

    for (String v : s2) {
        System.out.println(v);
    }

Again how do we join them after correcting the case?

     String s = "HELLO Java, JAVA IS INDEPENDENT. jAvA";         
     Pattern p=Pattern.compile("java.*", Pattern.CASE_INSENSITIVE);
     String[] s2=s.split("\\s");
      s="";
     for (String v : s2) {
         Matcher m=p.matcher(v);             
         if(m.matches()==true){
             v=v.toUpperCase();
             s=s+" "+v; 
         }
         else
            s=s+" "+v;                      
     }
     System.out.println(s);

You can just concatenate the string back together like so:

String finalStringWeNeed = "";
for(String v : s2) {
    finalStringWeNeed = finalStringWeNeed + v + " ";
}

Just use a regex, like this:

String x = s.replaceAll("[j|J][a|A][v|V][a|A]", "JAVA");

That's easier than using the split, especially since one of your Strings would have a comma in it (i.e. "Java,").
