将整数转换为字节数组（Java） 9个答案

假设我有两个字节映射的数字520给我数字：1000001000我想将这个数字（520）转换为另外两个数字，这些数字应该是：2和8因为00000010会给我2和00001000会给我8.我怎么能用java做到这一点？

This question already has an answer here:

Convert integer into byte array (Java) 9 answers

Suppose i have the number 520 that is mapped in two bytes that gives me the number: 1000001000 and i want to convert this number (520) to two other numbers, these numbers should be: 2 and 8 because 00000010 will give me 2 and 00001000 will give me 8. how can i do this with java?

最满意答案

像这样：

int theumber = 520; byte oneumber = (byte)theumber; byte otherumber = (byte)(theumber >> 8);

Like this:

int theumber = 520; byte oneumber = (byte)theumber; byte otherumber = (byte)(theumber >> 8);
