Folks - a Newbie ???

[G.Mark Stewart]

The program compiles, runs up to the first prompt, outputs the prompt,
and then
ignores any response keystrokes. What gives? Any ideas?

Thanks!



package cis261_lab1;
import java.util.Scanner; // program uses class Scanner
/**

* @author gmark
*/
public class Calculate {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// create a Scaner to obtain input from the command window
Scanner input = new Scanner( System.in );

int first; // first number to process
int second; // second number to process
int sum; // sum
int product; // product
int difference; // difference
int quotient; // quotient

System.out.print( "Enter first integer: " );
first = input.nextInt(); // read first integer from user

System.out.print( "Enter second integer: " );
second = input.nextInt(); // read second integer from user

sum = first + second; // add numbers, then store value in sum
product = first * second; // multiply numbers, then store
value in product
difference = first - second; // subtract numbers, then store
value in difference
quotient = first / second; // divide numbers, then store value
in quotient
sum = first + second; // add
numbers, then store value in sum
System.out.println( "Sum is " + sum );
System.out.println( "Product is " + product );
System.out.println( "Difference is " + difference );
System.out.println( "Quotient is " + quotient );
} // end method main
} // end class Calculate

To better assist, it would be nice to provide the log errors as well. Thanks.

Well, there were no errors -- the program just stopped as though I hadn't typed anything. ButI just ran it again today and it worked. No idea why.


I do have a problem with the C++ program, however. It doesn't recognize "cout", and I'm told
I have to in that the build not recognizing <iostream>. I've been told to add
the collection of cygwin tools to Netbeans 6.0 by going to the Tools -> Options
menu item.

Problem is that the top window menu bar on my machine does not have an "options" selection under
"tools". I'm going to try to reinstall the Netbeans IDE, just in case it's not a "version" problem,
but just a bad install of Netbeans.

Perhaps there's a work-around? Some other way of accessing this or putting a more complete path
into the #include statement? The basic issue is simply that the build blows up on the use of
"cout". For that matter, I don't mind using a command-line compiler method, if this is just
some limitation of Netbeans.


I've attached the output log and source below in case that above is not sufficiently explanatory.

Thanks!
