Question

For some reason.... I'm getting a null pointer exception..... while adding elements to an arraylist. I'm not even sure how that can happen...

Answer 1

here's the code snippet
```
public void hash(Scanner scan){
ArrayList resList = null;
ArrayList nameList = null;

String[] stringsForArray = getArray(scan);

for (String newElement : stringsForArray) {

if(isReserved(newElement)){

resList.add(newElement);
}

else{

nameList.add(newElement);
}


}
hashReserved(resList,scan);
hashName(nameList, scan);

}
```

Here's where the issue is
```
nameList.add(newElement);
