java.lang.IllegalArgumentException: Illegal pattern character 'Y' for SimpleDateFormat

Question

The following code:

Calendar now = Calendar.getInstance();
month = now.get(Calendar.MONTH) + 1;
year = now.get(Calendar.YEAR);
System.out.println(\"Month \"          


        

Answer 1

On your Local you might be using Java 8, so do check the version of Java on your Server. If it is less than Java JDK 7 the capital Y will not work.

Refer To Java 6 Oracle Docs for SimpleDateFormat

You have to write year in small y not in capitals Y.

Like for 2 digit year:

 SimpleDateFormat dt1 = new SimpleDateFormat("yy");

And for 4 digit year:

 SimpleDateFormat dt1 = new SimpleDateFormat("yyyy");

In case if you are using Java 7 or above: You can use the capital Y which represents Week Year.
