convert string array to int

[curioustoknow]

I need some help please. I am trying to convert an arraylist :

 public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);

        String Months[] = {"January","February","March","April","Main", "June", "July", "August",
                          "September","October","November","December"};
  

       System.out.print("Please enter an integer value for the month (e.g., 2 for February) : ");
       int monthvalue = keyboard.nextInt();

   while (monthvalue<=0 || monthvalue>=13)
        {
           System.out.print("You have entered an invalid month entry, please enter a value from 1-12:");
           monthvalue = keyboard.nextInt();
        }
        if(monthvalue == 1) 

          Months = Months[monthvalue-1];   [COLOR="Red"]// this gives me an error, how can I fix it?[/COLOR]

into an integer.

if you are trying to get the input from the user and convert that to an int then you can use:

Integer.parseInt(string);

Second, you are getting an error at the end because Months is an array, your left side of the statement is incorrect.

how can I fix my last statement to have it read a string. for example if user enter 1, it should read Month[0] which is January and so on

What error do you receive? Is it runtime or compile error, kindly post the complete error message.

[curioustoknow]

incompatible javatypes
required: java.lang.string[]
found: int

[curioustoknow]

ok, I figure it out by using tostring method. now how can I force a check for each month, lets say the user enter 28 for january, it should show an error and only accept 31. and so on for the other months.

Is this an assignment or what? Kindly show your lastest code so we are updated on the changes you made?
Have you try Calendar?

[curioustoknow]

I prefer not to pose it here

or Date class? I am not an expert but you might need computation like, to get last day of febuary you need a date which is March 1, <chosen year> then minus 1 day so the result will be the last day of febuary

The actual output is August 1, 2011 monday
What is your input?
And what is your expected output?

EDITED: I edited the reply and remove the code as respect to the OP's request.

So what is your input?
What is your expected output?
Base on you last message the output is August 1, 2011

[curioustoknow]

input is to enter an integer month (1 for jan, 2 for feb ...)
and also enter a value of the day (1-31).
the output should be something like: August 1, 2011 falls on a monday
