java - Access denied for User 'root'@'localhost' (using password: YES )

I would like to connect with my local MYSQL data base, which is installed along with XAMP server. I created a new User ie, " NewUser " and its password is "password". I given all PRIVILEGES to this user.

I write the code to connect with data base by using user "root" (No password for this user).
Its connected . Like bellow..

return DriverManager.getConnection("jdbc:MySql://localhost/database_name","root","");

Now I wrote the code to connect with same data base by another user ie, "NewUser" and its pasword "password"

return DriverManager.getConnection("jdbc:MySql://localhost/database_name","NewUser","password");

but its not connected.
The error in console is

java.sql.SQLException: Access denied for user 'NewUser'@'localhost' (using password: YES)

I give the host type while providing PRIVILEGES to this user, as " any host" ie."%".

If I change this to " localhost " or "127.0.0.1" its working.

So How can i use my database with " anyhost " PRIVILEGES to the particular user like "NewUser" .

If I got success here then I successes in connection to client live Data base..

Thanks to all and please let me out from this one.....
