مثال

public static void main( String[] args ) {
switch ( args.length ) {
case 0:
System.out.println("No parameters"); //$NON-NLS-1$
break ;
default :
System.out.println("Parameters: "); //$NON-NLS-1$
for ( int i = 0, n = args.length; i < n; i ++){
System.out.println(args[i]);
}
break ;
}
}

الحل

استخدام عبارة if/else بدلا من ذلك.

public static void main( String[] args ) {
if ( args.length == 0 ){
System.out.println("No Paramaters");
}else {
System.out.println("Parameters: "); //$NON-NLS-1$
for ( int i = 0, n = args.length; i < n; i ++){
System.out.println(args[i]);
}
}
}
