我必須使用java設置半字節的整數。老實說,我很困惑如何移動/設置/更改一個半字節到我想要的半字節。我的電訊管理局告訴我,它應該是大約5行代碼,但我不知道如何啓動它。任何幫助是極大的讚賞。設置半字節爲int - java
/* Examples:
* setNibble(0xAAA5, 0x1, 0); // => 0xAAA1
* setNibble(0x56B2, 0xF, 3); // => 0xF6B2
*
* @param num The int that will be modified.
* @param nibble The nibble to insert into the integer.
* @param which Selects which nibble to modify - 0 for least-significant nibble.
*
* @return The modified int.
*/
public static int setNibble(int num, int nibble, int which) {
// i know I will be using bit-wise operators but do not know how to use
// them in this situation
return 0;
}
所以我有這樣的東西在我的方法裏面,int temp =(num >> which); \t \t temp =(temp << 4)|蠶食; \t \t return temp; –
你不想改變'num',因爲這樣你會失去位。只需移動你的面具和*半字節*。 – MrSmith42
謝謝,我會給它一個鏡頭,並給你反饋 –
