Actually, we need to perform flush-privileges operation to tell the server to reload the grant tables. This can be done by issuing FLUSH PRIVILEGES statement or by executing a mysqladmin flush-privileges or mysqladmin reload command. FLUSH PRIVILEGES is really needed if we modify the grant tables directly using such as INSERT, UPDATE or DELETE, the changes have no effect on privileges checking until we either restart the server or tell it to reload the tables. But, Privileges assigned through GRANT choice don't want FLUSH PRIVILEGES to take effect - MySQL server cannotice these changes and reload the grant tables instantly. ... Read More

When you store a String asString str1 = "Hello";directly, then JVM creates a String object with the given value in a separate block of memory known as String constant pool.And whenever we try to create another String asString str2 = "Hello";JVM verifies whether any String object with the same value exists in the String constant pool, if so, instead of creating a new object JVM assigns the reference of the existing object to the new variable.And when we store String asString str = new String("Hello");using the new keyword, a new object with the given value is created irrespective of the ...
