Create User-Defined Exception and Arguments passed through Command line in Java.

Create a user-defined exception named Check Argument to check the number of arguments passed through command line.If the number of arguments is less than five, throw the Check Argument exception, else print the addition of all the five numbers

Program:


class CheckArgument extends Exception{
}

class command
{
     public static void main(String ag[]){
         int i,j;
int ans=0;
         int s[]=new int[5];
         try
        {
int cnt=0;
for(i=0;i<s.length;i++)
{
                   s[i]=Integer.parseInt(ag[i]);
                   cnt++;
                    if(ag.length<5){
throw new CheckArgument();
                    }
else if(ag.length>5){
throw new CheckArgument();
                    }
}

for(i=0;i<s.length;i++)
{
                 ans=ans+s[i];
}
   }
catch(CheckArgument m)
{
        System.out.println("Passed 5 Integer");
}  
System.out.println("The sum is"+ans);
  }
}
