Use compareTo() to get the difference in time in Milliseconds,<br />
<br />
from this you can get the difference of days,<br />
<br />
int time = cal1.compareTo(cal2);<br />
<br />
int days = time / 1000*60*60*24<br />

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.
