I have a class with about 20 methods which all catch 1 or more Exceptions and then respond to the user based on that Exception. Instead of writing them over and over again, I want to create a single method which is passed the Exception, handles it, and gives the appropriate response. 

Here's an example

```
public boolean addFirst(Object data){

    try {
        //add something 
        return true;
    } catch(Exception e) {
        exceptionHandler(e);
        return false;
    } 
}

```

But when I try to compare it with "e" it gives me "*Exception* cannot be resolved to a variable".

```
private void exceptionHandler(Exception e) {
    if(e == UnsupportedOperationException) {
        System.out.println("Operation is not supported.");
    } else if (e == ClassCastException) {
        System.out.println("Class of the specified element prevents it from being added to this list.");
    } else if (e == NullPointerException) {
        System.out.println("You cannot enter nothing.");
    } else if (e == IndexOutOfBoundsException) {
        System.out.println("Your specified index is larger than the size of the LinkedList. Please choose a lower value.");
    } else if(e == Exception) {
        System.out.println("You messed up so hard that I don't even know what you did wrong."); 
    }
}

```
