问题：直接看下面的代码：

	Long a1 = 1l;
	Long b1 = 1l;
	System.out.println(a1 == b1);
	Long a2 = new Long(1);
	Long b2 = 1l;
	System.out.println(a2 == b2);

public boolean equals(Object obj) {
        if (obj instanceof Long) {
            return value == ((Long)obj).longValue();
        }
        return false;
}
