Can someone please tell me what is wrong with this code?
public
Console.OUT.println(
}
Console.OUT.println(classHello
{publicstaticdefmain(args:Rail[String]!){if(args.length>0){"The first arg is:
"+args(0));"Enter a number: ");valh = newHello(); // final variable
h.myMethod();
}
Console.OUT.println(
Console.OUT.println(
s++;
}
Console.OUT.println(s);
}
}
}
and the result is
Enter a number: 10The read number is: 10
The sum of the first 10
numbers is: java.lang.NumberFormatException

As far as I understand, the readLine function reads a string, and
Int.parseInt(string) will convert it to a number, the question is what I do
wrong... can someone please tell me? Thank you.: For input string:
"10Hello.java:130)Hello.java:93)Hello.java:52)Runtime.java:310)Activity.java:127)Runtime.java:1599)Runtime.java:101)Runtime.java:1566)Worker.java:302)Worker.java:193)Pool.java:207)Runtime.java:317)Hello.java:35)Runtime.java:46)/**

Console.IN.readLine();"The read number is: "+limit);"The sum of the first
"+limit+" numbers is: ");vars:int=0;valn:int =
Int.parseInt(limit);for(vari:int=0;i<n;i++){catch(e:IOException){}
