Java Identifier Expected

[Mr.Macdonald]

First off, yes this is homework. But don't freak out, because I just want a compiler error fixed. I have been programming for 4 years, I avoided Java for the last 3 of those to find that college uses it!!

So ...

Code (LimCapList Provided by teacher)

public class Array12<E> implements LimCapList<E> {
Object[] array;
int head;
int tail;

public static final int DEFAULT_CAPACITY = 10;

public Array12<E>() {
array = new Object[DEFAULT_CAPACITY];
head = tail = -1;
}

public Array12<E>(int cap) {
array = new Object[cap];
head = tail = -1;
}

... Other Stuff ...

}


Commands

$ javac Array12.java
Array12.java:9: <identifier> expected
public Array12<E>() {
^
Array12.java:14: <identifier> expected
public Array12<E>(int cap) {
^
2 errors


Don't write a class for me, just fix the error. Java and I don't work well together!

Thank you

Constructors don't need a generic after the name. Just take out the <E> in Array12<E>() and Array12<E>(int cap).

Wow, that simple
Thanks

Well yea, this will work, but you're teetering on the edge of one of the ugliest parts of Java. See that Object[] array? Since that's the storage container for a class of type E, shouldn't it store only E's and not anything that inherets from Object (which is everything)?

So try changing Object[] into E[] and see what happens (particularly when you try to create a new E[] ).

Excatly...
