Java Programming

Anyone know whats up with this code?


public class q16
{
public static void main(String[] args)
{
int count;
int index;
int sum;
int average;
count = 10;
index = sum = count + 5;
sum = count + index * 2;
average = count + sum + index / 5;

}
}

for some reason average is never being read?

Read into what?

If you create it as an object it comes to 53.

Use a debugger..but my guess is that it bombs out without getting into the function or class.

Thanks for the reply guys.

Just figured it out. I forgot to put System.Out.println(average)

I saw that straight away. Wondered how long it would take you to work it out.

Is anyone any good at Java programming who I can PM about a couple of questions?

Really stuck on a couple of daft questions.

Can anyone who has eclipse and good at Java know how to stop this code from producing an infinite loop?


public class loop {


public static void main(String[] args) {
// TODO Auto-generated method stub
int total = 0;
int count = 0;
while (count < 10)
{
System.out.print(count + "*");
total = total + count;
}
System.out.println(total);
}

}

}

You aren't incrementing count?

 

[JamesMCFC]

Yeah sorry meant to put a number there

but when i do it produces an continuous loop still
