This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
1. I have a class named 'node' and a vector made up of nodes. When I use a vector method like lastElement(), an Object is returned, not a node. However, I need a node to manipulate with as a result of this method call - for eg, I assign the node that I would like returned from the method to a newly created node. How do I tackle this?
2. How do I read character input from the console? i.e., objects of type 'char'?
If you are positive that only Nodes will be in the vector, Tim's solution is perfect. if there is ANY chance there might be something OTHER than a node in there, you may want to use the 'instanceOf' operator to make sure before you do your cast.
