parsing a comparable to a string...

ok, so heres what i have...

Code:

---

Comparable nodeInput = JOptionPane.showInputDialog(null);

---

i just need to know what line of code i would need to use if i wanted to parse that to an integer...

i have tried the following...

Code:

---

tree.insert(new Integer(Integer.parseInt(nodeInput)));

---

the error i get is that my IDE says that the symbol method parseInt could not be found...

thanks for any help in advance.

That is because the Integer has two parseInt methods. One takes a string, and the other takes a String and an int. There is not a parseInt method that takes a Comparable object.

Strings are already Comparable and showInputDialog does return a String object, so why not use Strings?

that worked perfect, I was under the impression that i had to use comparables, because im utilising another class called BinarySearchTree, and it uses comparables...

thanks for the help!

Yes, and since the String class Implements Comparable it can be used as a Comparable object. That means it can be passed around as a Comparable object and hence why your code :Comparable c = JOp... worked.
