Hi dapim,
have a look at the example here:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Hashtable.html
If your Hashtable looks like this:
Hashtable numbers = new Hashtable();
numbers.put("one", new Integer(1));
numbers.put("two", new Integer(2));
numbers.put("three", new Integer(3));You could access it like this
Integer n = (Integer)numbers.get(JTextField.getText());
- use the interface not the implementation as declaring type
- use HashMap not Hashtable if it's only accessed by a single thread
- use generics
- use autoboxing to allow the reuse of objects
So this code would look like this:
Map<String, Integer> numbers = new HashMap<String, Integer>();
numbers.put("one", 1);
numbers.put("two", 2);
numbers.put("three", 3);
int n = numbers.get(myTextField.getText());-Puce
