write a code to declare arrays that will hold calendar (january to december code example

Example 1: Write code to declare an array that will hold calendar months (.e. January to December) java

public class App {

    public static String months[];

    public static void main ( String[] args ) {

        months = new String[ 13 ];
        months[ 0 ] = null;
        months[ 1 ] = "January";
        months[ 2 ] = "February";
        months[ 3 ] = "March";
        months[ 4 ] = "April";
        months[ 5 ] = "May";
        months[ 6 ] = "June";
        months[ 7 ] = "July";
        months[ 8 ] = "August";
        months[ 9 ] = "September";
        months[ 10 ] = "October";
        months[ 11 ] = "November";
        months[ 12 ] = "December";

        System.out.println ( "DEBUG args: " + Arrays.toString ( args ) );
        if ( args.length == 0 ) {
            System.out.println ( "No month specified. No arguments passed to 'main' method." );
        } else if ( args.length == 1 ) {  // Else we have a single argument as expected.
            int m = Integer.parseInt ( args[ 0 ] );
            System.out.println ( months[ m ] );
        } else if ( args.length > 1 ) {  // Else we have multiple arguments, but expected only one.
            System.out.println ( "ERROR - more than one argument passed to 'main' method." );
        } else {  // Else impossible. Should not reach this point. Defensive programming.
            System.out.println ( "ERROR - Unexpectedly reached IF-ELSE. Should be impossible." );
        }
