		str1.concat("Resources");

		System.out.println(str1);

		// again, concatenating - need to assign it explicitly
		str1 = str1.concat("Resources.Net");

		// printing to the console - str1
		System.out.println(str1);

		// concatenating multiple strings, at once
		String str2 = "This weblog has".concat(" lot of")
