multiplication

what is the problem in this code
class ManageTables
{
public static void main(String[] args)
{
for(int i=0;i<11;i++)
{
int k =1;
int y=9;
int z =(y*k);
System.out.println("9"+" * "+k+" = "+z);
k++;
}
}
}//problem is k is not incrementing..

problem is k is not incrementing..

Ask yourself, where did I declare k ? And where did I initialize it ?

Also why have 2 counters = i and k?

an easy way to figure this out would be to pepper your code with println() statements. Each time you do ANYTHING to k, put in a print statement...

class ManageTables
{
  public static void main(String[] args)
  {
  for(int i=0;i<11;i++)
    {
    int k =1;
    System.out.prinln("debug 1 - k is now :" + k + ":");
    int y=9;
    int z =(y*k);
    System.out.println("9"+" * "+k+" = "+z);
    k++;
    System.out.prinln("debug 2 - k is now :" + k + ":");
    }
  }
}

put in something like 'debug' so you know what to take out, and number each line so you can tell which is which in your output.

you will eventually learn cleaner ways to do this (with tools like log4j for example), but this works for simple programs - and often for complex ones too, in many cases.
