import com.google.common.base.Joiner;

public class JoinTest {

  /**
   @param args
   */
  public static void main(String[] args) {
    Joiner joiner = Joiner.on(":");
    String str = joiner.join("One""Two""Three""Four")
                //We shouldn't pass null values here
                //To handle nulls we should either use
                //skipNulls() or useForNull(String) methods
                //Throws NullPointerException otherwise
    System.out.println(str);
  }

}
   

It gives the following output,
