Why `java.lang.ArrayIndexOutOfBoundsException: 0` with `main` method arguments [closed]

Answer 1

JVM throw exception bcoz no element exist at index 0 in the array.So provide the parameter during running the class or just add below code so that no exception will raise :

    if(args.length >= 1)
       {
           System.out.println(formattedDate + "> Hello, " + args[0] + "!"); 
       }

Pass the argument as below :

java My.Hello BHARAT
