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 ) {
int m = Integer.parseInt ( args[ 0 ] );
System.out.println ( months[ m ] );
} else if ( args.length > 1 ) {
System.out.println ( "ERROR - more than one argument passed to 'main' method." );
} else {
System.out.println ( "ERROR - Unexpectedly reached IF-ELSE. Should be impossible." );
}
