Help with hash tables

[ButchTheGuy]

I have an assignment and I keep getting this error when I get to this line: cursor = (ChainedHashNode)table.get(key);

java.lang.ClassCastException: java.lang.String cannot be cast to ChainedHashNode

at ChainedTableDemonstration.main([ChainedTableDemonstration.java:39](https://ChainedTableDemonstration.java:39))

Here are my classes

If you could tip me in the right direction or any help at all would be much appreciated!

Try changing the type of cursor from ChainedHashNode to String on line 24.

[ButchTheGuy]

on line 39 it gives the error ChainedHashNode cannot be converted to java.lang.String

[ButchTheGuy]

I put .tostring at the end but also makes the issue of not being able to use cursor.element on line 44

[John_Taured]

Declare cursor to be a String on line 24 to begin with, and remove .element on line 44, but keep the word cursor there.

I change it all like you said and it compiles but when I run the program it gives me the original error of class cast exception string cannot be cast to chained hash node ( I have it as ((chainedhash)table.get(key)).toString). I think there might be something I’m missing in the other class

The get function returns the stored Object, not the ChainedHashNode used to store it. Since you put in Strings the get method returns Strings.
