Java Project Connectivity Code

Example : A Connectivity Code between Net Beans 8.2 IDE & Oracle 10g/11g (First Step)  [NetBeans – Oracle Connectivity Code].

Step 1 - First, Download 'ojdbc7' jar driver file free  and store at specific location using Google.

Step 2 - Add 'ojdbc7' jar file into 'Libraries' option of 'Project' tab.(Open Net Beans 8.2 IDE -
