hi, i have to write a program that calculates and displays numbers btw 1 and 100 incl

[monkey1001]

this is what i got and am stuck...please helpp..thanks

[CODE=java]import java.util.Rando m; //Needed for Scanner class
import java.util.*;

/**
This program demonstrates value between 1 and 100 inclusive
*/

public class Value
{
public static int getValidValue()

{
Scanner keyboard = new Scanner(System. in);

int inputValue=0;
System.out.prin t("Enter an integer between" + "1 and 100;inclusive:" );

inputValue = keyboard.nextln ();

sum=n(n+1)/2;
System.out.prin tln(sum);
System.out.prin tln();
{
while (inputValue <1 ||inputValue > 100)
{
System.out.prin t("Invaalid value" + "enter a value between 1" + "and 100,inclusive:" );

inputValue = keyboard.nextIn t();

}
return(inputVal ue);
}
}
}[/CODE]

return(inputVal ue);
}
}
}

First why is there a "+" in this line?
System.out.prin t("Enter an integer between" + "1 and 100;inclusive:" );

second, sum=n(n+1)/2; what is n?

the "n" stands for user entered value and the "+" represntd "and"

[Ganon11]

The syntax n(n+1)/2 will not compile. You need to use the * operator:

[CODE=java]sum = (n * (n + 1)) / 2;[/CODE]

But apart from this, your code is a mess. You never make an n variable, you never get a value for it, sum is initialized, but then printed and not used again. If you get rid of this, you will have exactly what the method describes - you ask for input, get it in the form of an int, and then check if it is between 1 and 100. What is all the rest of that for anyway?

[MarshMallow]

rename n with inputvalue;
move the while loop before the computation(who y should computation start if the input is not correct?);
change the comment in "computing the sum of first n integer,where n is the userinput"(this is what your formula 'n(n+1)/2' is supposed to do);
