Regarding + in string and \n .

[WeiJie Lim]

"Welcome to the voting machine "
				   + "error code decoder.\n\n"
				   + "If your voting machine generates "
				   + "an error code,\n"
				   + "you can use this program to determine "
				   + "the exact\ncause of the error.\n");

The above code will result in :
Welcome to the voting machine error code decoder.

If your voting machine generates an error code,
you can use this program to determine the exact
cause of the error.

However, I decide to remove all the + . I didn't think it is neccessary.. or am I wrong. Nevertheless, I tried and the result is really different. Why is this so ?
I tried :

("Welcome to the voting machine 
		  error code decoder.\n\n
		   If your voting machine generates 
		 an error code,\nyou can use this program to determine the exact\n cause of the error.\n");

Resulted in :
Welcome to the voting machine error code decoder.
If your voting machine generates an error code,
you can use this program to determine
the exact
cause of the error.

to be honest I am suprised it compiled, when i cut and paste it into eclipse

System.out.println("Welcome to the voting machine   
		          error code decoder.\n\n  
		           If your voting machine generates   
		         an error code,\nyou can use this program to determine the exact\n cause of the error.\n");

it didn't compile. So any results you get are completely random, as strings are not meant to go over line ends (wrap).
That is what all the + are for

You can do that but then you would need to write the whole string on one line, otherwise you will get compiler errors, as Wendy tried. Java does not allow you to open a string literal on one line and close it on another line.
