public Stack() Constructs a stack with the default size of {@code Vector}. since Android 1.0 super();

Methods Summary
public boolean	empty() Returns whether the stack is empty or not. return {@code true} if the stack is empty, {@code false} otherwise. since Android 1.0 return elementCount == 0;
public synchronized E	peek() Returns the element at the top of the stack without removing it. return the element at the top of the stack. throws EmptyStackException if the stack is empty. see #pop since Android 1.0 try { return (E)elementData[elementCount - 1]; } catch (IndexOutOfBoundsException e) { throw new EmptyStackException(); }
public synchronized E	pop() Returns the element at the top of the stack and removes it. return the element at the top of the stack. throws EmptyStackException if the stack is empty. see #peek see #push since Android 1.0 try { int index = elementCount - 1; E obj = (E)elementData[index]; removeElementAt(index); return obj; } catch (IndexOutOfBoundsException e) { throw new EmptyStackException(); }
public synchronized E	push(E object) Pushes the specified object onto the top of the stack. param object The object to be added on top of the stack. return the object argument. see #peek see #pop since Android 1.0 addElement(object); return object;
public synchronized int	search(java.lang.Object o) Returns the index of the first occurrence of the object, starting from the top of the stack. return the index of the first occurrence of the object, assuming that the topmost object on the stack has a distance of one. param o the object to be searched. since Android 1.0 int index = lastIndexOf(o); if (index >= 0) return (elementCount - index); return -1;
