Java数据结构源码究竟包含哪些核心组件？

Java中的数据结构源码非常复杂，涉及到许多类和方法，这里我将为您提供一个简单的示例，即ArrayList的源码解析。

import java.util.Arrays;
public class ArrayList<E> extends AbstractList<E> implements List<E>, RandomAccess, Cloneable, java.io.Serializable {
    private static final int DEFAULT_CAPACITY = 10;
    private static final Object[] EMPTY_ELEMENTDATA = {};
    private static final Object[] DEFAULTCAPACITY_EMPTY_ELEMENTDATA = {};
    transient Object[] elementData; // nonprivate to simplify nested class access
    private int size;
    public ArrayList() {
        this.elementData = DEFAULTCAPACITY_EMPTY_ELEMENTDATA;
    }
    public ArrayList(int initialCapacity) {
        if (initialCapacity > 0) {
            this.elementData = new Object[initialCapacity];
        } else if (initialCapacity == 0) {
            this.elementData = EMPTY_ELEMENTDATA;
        } else {
            throw new IllegalArgumentException("Illegal Capacity: " + initialCapacity);
        }
    }
    public boolean add(E e) {
        ensureExplicitCapacity(size + 1);
        elementData[size++] = e;
        return true;
    }
    public E get(int index) {
        rangeCheck(index);
        return elementData(index);
    }
    public E set(int index, E element) {
        rangeCheck(index);
        E oldValue = elementData(index);
        elementData[index] = element;
        return oldValue;
    }
    public void ensureExplicitCapacity(int minCapacity) {
        modCount++;
        if (minCapacity  elementData.length > 0)
            grow(minCapacity);
    }
    private void grow(int minCapacity) {
        // overflowconscious code
        int oldCapacity = elementData.length;
        int newCapacity = oldCapacity + (oldCapacity >> 1);
        if (newCapacity  minCapacity < 0)
            newCapacity = minCapacity;
        if (newCapacity  MAX_ARRAY_SIZE > 0)
            newCapacity = hugeCapacity(minCapacity);
        // minCapacity is usually close to size, so this is a win:
        elementData = Arrays.copyOf(elementData, newCapacity);
    }
    private static int hugeCapacity(int minCapacity) {
        if (minCapacity < 0) // overflow
            throw new OutOfMemoryError();
        return (minCapacity > MAX_ARRAY_SIZE) ? Integer.MAX_VALUE : MAX_ARRAY_SIZE;
    }
    private void rangeCheck(int index) {
        if (index >= size || index < 0)
            throw new IndexOutOfBoundsException("Index: " + index + ", Size: " + size);
    }
}

这是一个简化版的ArrayList实现，仅包含了部分方法，完整的ArrayList实现还包括其他方法，如remove、clear等，还有许多其他的Java数据结构，如LinkedList、HashSet、HashMap等，它们的源码同样非常复杂，如果您需要详细了解某个具体的数据结构的源码，请告诉我，我会为您提供相应的代码片段。
