case 1: System.out.println("GREEN");
break;
case 2: System.out.println("RED");

default: System.out.println("invalid number");
}}}

Answer 1

args.length is 0 So
It's mean no value n array inside args
ArrayIndexOutOfBoundsException is error that um.....Why I always have a disease?!.I'm not good at explain again.
Jump to example then
int[] a = {1,2,3};
System.out.print(a[3]);
No [3] inside the variable a that is error.
Sum :
Out of array's size
Btw I need some milk

Answer 2

Where are you passing the value in the program to the array?
