What is the difference between the execute, executeQuery, and executeUpdate methods in JDBC?

The execute method in JDBC is used to execute any SQL statement, it can be used for both queries and updates. The executeQuery method is specifically used for executing SELECT queries and returns a ResultSet object containing the query results. On the other hand, the executeUpdate method is used for executing INSERT, UPDATE, DELETE, and other SQL statements that do not return a result set but instead return the number of rows affected.
