Hi all

I've been through the array tutorials on this forum several times, but still struggling with the code for this exercise. I need to write a code that accepts a integer parameter in a set range, in this case represented by days and I would like the result returned as the day corresponding to the parameter.

Can anyone help please,

The declaration for the array is as follows;

String [] day = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};

I Know I need to use ; public String getDayName(int dayNumber) {
return(day[dayNumber-1]);}

but I'm not sure how to put the code together.

Anyone, your help or advice would be greatly appreciated.

You've posted this in the wrong place. I'm going to guess this is C# and move it there.

I would use the GetValue method of the array, something like this

public string GetValueFromArray(int index)
{
	string[] day = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };
	return day.GetValue(index).ToString();
}

Hi and thanks for the help but can you Please move my topic back to where it originated as the problem posed is a java one. As it is Java I'm trying to learn.

Thanks again

p.s don't need the code just a better unstanding of what I am trying to achieve.

[PsychoCoder]

I can do that. Forget the code then, it's C# code.

Moved back to Java

The topic was originally posted in Introduce Yourself, not Java. I thought it was C# so I moved it there.

There's not much to it - all you need to do is place the code you quoted before the return statement

[ayman_mastermind]

As goose said, something like this:

public String getDayName(int dayNumber) 
{
String [] day = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};

return(day[dayNumber-1]);
}

Good Luck

And observe that if a value out of the range 1~7 is passed you will get an ArrayIndexOutOfBoundException.

Please stop creating new threads for the same topic. The thread you opened yesterday on the subject that PsychoCoder and JackOfAllTrades were helping you in would have been a good place. Look- if your thread falls to the bottom of the page, you can always bump it. Thanks!

Also, in terms of your problem, it would be more memory efficient to store the String[] containing the days as a global variable in your class, rather than as a local variable in your method. What will happen is that each time your method is invoked, the Array is created again. So to illustrate:

class YourClassNameHere{
   String [] day ={"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};

   public String getDayName(int dayNumber){
	   return day[dayNumber-1]; 
	} 
   ..other code..
}

That's certainly true. Better still, declare it as

public static final String [] day ={"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
