可以使用String.format方法将每个字节转换为两位的十六进制数。 将所有转换后的16进制字符串连接起来: 使用StringBuilder来拼接转换后的十六进制字符串,以提高性能。 输出或返回最终的16进制字符串: 将拼接好的十六进制字符串输出或返回给调用者。 下面是具体的代码实现: java public class HexConverter { // 将字节数...

将bytes 转化为hex,1、各种数据转换为String将整数int转换成字串StringA.有叁种方法:1.)Strings=String.valueOf(i);2.)Strings=Integer.toString(i);3.)Strings=""+i;注:Double,Float,Long转成字串的方法大同小异.Date-->Strin
