Common Issue
When you use java.util.Date object with JDK version higher than 1.1
Date d = new Date();
d.getMonth();
You will get deprecated warning messages when you try to compile
The method getMonth() from the type Date is deprecated
However you can supress the warning message by adding @SuppressWarnings("deprecation") to you main() method
@SuppressWarnings("deprecation")
public static void main(String[] args) {
...
}or adding @SuppressWarnings("unchecked") to other method
@SuppressWarnings("unchecked")
public void otherMethod() {
...
}Note that this can only be used in JDK 5.0+
Alternative
Now let's forget about working around the deprecated method, let's learn how to use java.util.Calendar instead
