Java: I just need the 4 code segments to
implement stacks using a DynamicArray generic
type <E>:
}
}
}
1 // PROGRAMMER: John Doe 2 public class DynamicStack<E> 3 { 4 // INSTANCE VARIABLES DynamicArray<E> stack; 6 7 // CONSTRUCTORS 8 public Dynamic Stack() 9 { 10 stack = new DynamicArray<E>(); 11 } 12 13 public DynamicStack(E element) 14 15 // ENTER CODE HERE ... 16 } 17 18 public DynamicStack(E[] array) 19 20 // ENTER CODE HERE 21 22 } 23 24 // INSTANCE METHODS 25 public void push(E element) 26 { stack.addToEnd (element); 28 } 29 30 public Epop) 31 { 32 // ENTER CODE HERE 33 { 35 throw new RuntimeException("Empty Stack"); 36 } 37 return( stack.remove(stack.getNumberOfElements () - 1) ); 38 } 39 40 public E peek) 41 { 42 // ENTER CODE HERE ... 43 { 44 throw new RuntimeException("Empty Stack"); 45 } 46 return( stack.get( stack.getNumberOfElements() - 1) ); 47 } 48 49 public boolean empty() 50 51 if(stack.getNumberOfElements() == 0) 52 { 53 return(true); 54 55 else 56 { 57 return(false); }
