我必须为家庭作业编写此代码，但我什至不知道从哪里开始。这是我必须编写的方法的javadoc。
/**
* Sets a 4-bit nibble in an int
* Ints are made of eight bytes, numbered like so: 7777 6666 5555 4444 3333 2222 1111 0000
*
* For a graphical representation of this:
* 1 1 1 1 1 1
* 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0
* +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
* |Nibble3|Nibble2|Nibble1|Nibble0|
* +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
*
* Examples:
* setNibble(0xAAA5, 0x1, 0) //=> 0xAAA1
* setNibble(0x56B2, 0xF, 3) //=> 0xF6B2
*
* @param num int that will be modified
* @param nibble nibble to insert into the integer
* @param which determines which nibble gets modified - 0 for least significant nibble
*
* @return the modified int
*/
这就是我所拥有的。我已经让它与 javadoc 中的第一个示例一起工作，但我知道这并不适用于所有情况。特别是当 int which != 0;
public static int setNibble(int num, int nibble, int which)
{
int newNibble = (num >> 4);
newNibble = (newNibble << 4) | nibble;
return newNibble;
}
我应该使用轮班还是不使用？有人告诉我，我可以在一行代码中执行此方法。感谢您在高级的帮助！
