<div>
First example you give: 30 0/1 * * * ? <br />
<br />
This means it wil start every 30 minutes in each hour. So 13:30, 14:30, 15:30 etcetera<br />
<br />
Second example: 0 0/2 * * * ? <br />
It will run every 2 hours at 00 minutes. So 00:00, 02:00, 04:00 etcetera<br />
<br />
Both will be executed every day.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
