Hashtable in core of a class

Question

Hi,
I try to use Hashtable in the core of a public class.
But I cannot access to put method from Hashtable from the core of the class.
I must access put method from a method of this class.
Why ?
import java.util.Hashtable;
public class Help {
Hashtable<String, String> helpHash = new Hashtable<String, String>();
Thanks

I love these.
import java.util.Hashtable;
public class Help {
Hashtable<String, String> helpHash = new Hashtable<String, String>();
}There doesn't appear to be any problems there.
Unfortunately for you, the part you elipsed is the part where your problems occur. Without knowing what the hell you're referring to when you say
But I cannot access to put method from Hashtable from the core of the class. I must access put method from a method of this class. Why?we subsequently cannot help you.
If it's any help, please be aware that all code that manipulates objects (unless it's lazy instantiation) must be in constructor/method bodies (between { and }'s).
You can't just have this:
import java.util.Hashtable;
public class Help {
Hashtable<String, String> helpHash = new Hashtable<String, String>();
helpHash.put(someObject);
}Illegal. :)
helpHash.put(someObject); must be in a constructor or method body. What you have above is just a class body. Constructor / method bodies are inside class bodies.
