If this program isn't for a course or isn't an exercise of some sort,
the following paragraph does not really apply to you.
I'd hate to discover I was cheating you out of learning for a course by
telling you the answer, but maybe this will help you learn the
fundamentals better.
I can't tell what you're asking in question 1, have you thought about
this thoroughly? Are you trying to run both with one command?
If so, you could possibly put in the first one, the one you want to run
from the command prompt, a line telling the other class to run.
That is, if your classes were something like
public class A
{
public static void main(String[] args)
{
System.out.println("Class A is running");
}
}
and an identical one with B instead of A, you could put instead for A:
public class A
{
public static void main(String[] args)
{
System.out.println("Class A is running");
B.main(args);
}
}
To see whether there was an input or not, you can do this: pretend your
code looks like the following, and has an additional
isPalindrome(String s) method.
public class B
{
public static void main(String[] args)
{
if(args == null)
System.out.println("No input!");
else
{
String wholestring = "";
for(int i = 0; i < args.length; i++)
wholestring += args[i];
if(isPalindrome(wholestring))
System.out.println("A palindrome");
else
System.out.prinltn("Not a palindrome");
}
}
//also there should be a boolean method
"isPalindrome(String)"
}
.
