Concatenating Strings in Java

Source:

public class ConcatenateString {

   public static void main(String args[]) {
      String string1 = "abcdefghijklm";
      String string2 = "nopqrstuvwxyz";
      String string3 = string1.concat(string2);

      System.out.println("string1: " + string1);
      System.out.println("string2: " + string2);
      System.out.println("string3: " + string3);
   }
}

Output:

   $ java ConcatenateString 
   string1: abcdefghijklm
   string2: nopqrstuvwxyz
   string3: abcdefghijklmnopqrstuvwxyz
