Não consegue conectar ao mysql atravez do -uroot , porém tenho o mysql instalado no computador e só funciona através da MySQL Command Line Client.

A partir do terminal do windows, não consigo me conectar ao MySQL, sempre mostra o seguinte erro:


C:\WINDOWS\system32>mysql -uroot
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

ou

C:\WINDOWS\system32>mysql -uroot -p
Enter password: ******
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Como posso conectar java ao MySQL usando o terminal do próprio MySQL?
