最近在项目中需要将字节数组转换成十六进制字符串,而Java内置的库中并没有相关工具可用,因此查了一下byte数组转hex字符串的相关方法,列出如下,需要可以直接拿来使用。 方法1:使用String.format publicstaticStringencodeHexString(byte[]data){StringBuildersb=newStringBuilder();for(byteb:data){sb.append(String.forma...
String str = "Hello World"; byte[] byteArray = str.getBytes(); 上述代码将字符串"Hello World"转换为字节数组。 要将字节数组转换回字符串,可以使用String的构造函数,将字节数组和指定的字符集作为参数。例如: 代码语言:txt 复制 byte[] byteArray = {72, 101, 108, 108,...
