在做對象克隆，尤其是深度克隆時，需要注意不僅僅對象的引用需要特殊處理，數組也一樣

public class ArrayCloneTest implements Cloneable{
    public byte[] source = new byte[] {(byte)127,(byte)1};
    @Override
    public ArrayCloneTest clone() throws CloneNotSupportedException {
        ArrayCloneTest gen = (ArrayCloneTest)super.clone();
        return gen;
    }
    public static void main(String[] args) {
        ArrayCloneTest test = new ArrayCloneTest();
        System.out.println(Arrays.toString(test.source));
        try {
            ArrayCloneTest clone = test.clone();
            clone.source[1] =(byte)2;
            System.out.println(Arrays.toString(clone.source));
            System.out.println(Arrays.toString(test.source));
        } catch (CloneNotSupportedException e) {
            e.printStackTrace();
        }
    }

}
