The difference is the first line will compile and the second will not as creating a string with a string makes no sense.

Solution 2

C#

  String s = "Test";
  //This Will Set value "Test" into string variable

   String sData = new String("Test");
   //This will give an error like this..
//The best overloaded method match for 'string.String(char*)' has some invalid arguments

The difference is that the first does compile, but the second does not. It gives this error:

Quote:
The best overloaded method match for 'string.String(char*)' has some invalid arguments

Why? Because the constructor of String does not take a string as argument. You can find an overload list here:
