Table 'mysql.user' doesn't exist:ERROR

Question

I am creating a db in mysql for a java program.My program works well in my friends system.But I have some problem with my mysql.

The query is below:

Answer 1

'Error Code: 1046'. 

This error shows that the table does not exist may sometimes be caused by having selected a different database and running a query referring to another table. The results indicates 'No database selected Select the default DB to be used by double-clicking its name in the SCHEMAS list in the sidebar'. Will solve the issue and it worked for me very well.
