print method in
StackTester.java (and
QueueTester.java), it is probably better
to add a toString method to the implementation
ArrayStack.java and replace
print(stack) in the
StackTester.java
with System.out.print(stack). The former does destroy the stack
whereas the latter doesn't.
/**
* Returns a string representation of this stack.
* @return A string representation of this stack.
*/
public String toString() {
String rep = "";
for (int i = 0; i <= top; i++) {
rep += stack[i].toString();
rep += "\n";
}
return rep;
}
Stack.java
The implements Stack in
ArrayStack.java
specifies that the class ArrayStack implements all the methods
of the interface Stack.
