char[] charArray = {'H', 'e', 'l', 'l', 'o'}; 创建一个相应大小的byte数组: 这里需要注意,如果我们使用UTF-8编码,每个char可能转换成1到4个byte,所以我们需要一个更大的数组来存储转换后的byte。但是,如果我们知道字符集是ASCII(每个字符只占用1个byte),则可以创建一个相同大小的byte数组。为了...

第四步:从byte数组恢复char值 从byte数组恢复char值需要将byte数组转换为字符串,然后取出字符: // 从byte数组恢复char值StringbyteToStr=newString(byteArray);// 创建一个新字符串charrestoredChar=byteToStr.charAt(0);// 获取字符串中的第一个字符System.out.println("恢复的字符: "+restoredChar); ...
