Concatenating Strings

//The String class includes a method for concatenating two strings :

string1.concat(string2);
This returns a new string that is string1 with string2 added to it at the end. You can also use the concat() method with string literals 

"My Name is".concat("Zara");
Strings are most commonly concatenated with the "+" operator

"Hello," + " world" + "!"
Example
public class StringDemo {

   public static void main(String args[]) {
      String string1 = "saw I was ";
      System.out.println("Dot " + string1 + "Tod");
   }
}
