Method Detail

containsKey

public boolean containsKey(java.lang.Object key)

---

get

public int get(java.lang.Object key)

Returns the value at the given key. Returns -1 if not found.

---

public int put(java.lang.Object key,
               int value)

---

size

public int size()

keySet

public java.util.Set keySet()

Return the keys.

---

sortedKeys

public java.lang.Object[] sortedKeys(int maxValue)

---

sortedKeys

public java.lang.Object[] sortedKeys()

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

---

rehash

private void rehash()

---

main

public static void main(java.lang.String[] args)

---

test

private static void test()
