i need to compare s1 values with s2 values if exists i need to return
the matched value.

hello in s1 is present in s2 ..i neeed to return hello...

You can use s1.split(",") and s2.split(",") to create two String
arrays. Then you compare the arrays element by element.

Or convert those arrays to Lists with Arrays.asList(T[]), make a HashSet
out of one of them, and pass the other to its retainAll(Collection) metho=

i tried out and got it

public class StringComp {
    public static void main(String args[]) {
        String s1 ="hello,test,from,cbn,party";
        String s2 = "jain,dead,hello,to,cbn";

        String sold [] = s1.split(",");
        for(int i =0 ;i<sold.length;i++) {
            String out = sold[i];
            String snew [] = s2.split(",");
            for(int j=0; j<snew.length; j++){
                String in = snew[j];
                if(in.equalsIgnoreCase(out)){
                    System.out.println("equal: " +in);
                }
            }
        }
    }
