在Java中,可以使用String类的构造函数或者通过使用编码(encoding)来将字节数组转换为字符串。下面是两种常见的方法示例: 使用String构造函数 byte[]byteArray={72,101,108,108,111};Stringstr=newString(byteArray);System.out.println(str); 1. 2. 3. 使用编码方式转换 byte[]byteArray={72,101,108,108,111...
Usingnew String(byOriginal)and converting back tobyte[]usinggetBytes()doesn't guarantee twobyte[]with equal values. This is due to a call toStringCoding.encode(..)which will encode theStringto. During this encoding, the encoder might choose to replace unknown characters and do other changes. ...

Java语言中字符串类型和字节数组类型相互之间的转换经常发生,网上的分析及代码也比较多,本文将分析总结常规的byte[]和String间的转换以及十六进制String和byte[]间相互转换的原理及实现。 1. String转byte[] 首先我们来分析一下常规的String转byte[]的方法,代码如下:publicstaticbyte[] strToByteArray(String str) ...

从Java 8 开始可以使用Base64这个类 import java.util.Base64; public class StringByteArrayExamples { public static void main(String[] args) { //Original byte[] byte[] bytes = "hello world".getBytes(); //Base64 Encoded String encoded = Base64.getEncoder().encodeToString(bytes); ...
Convert a byte array to a Hex stringTag(s): The simple way public static String getHexString(byte[] b) throws Exception { String result = ""; for (int i=0; i < b.length; i++) { result += Integer.toString( ( b[i] & 0xff ) + 0x100, 16).substring( 1 ); ...
1.Array转List，通过java.util.Arrays.asList(T... a)参数是可变泛型参数 2.List转Array⽤.toArray(T[] a)3.String转byte[]4.byte[]转String 总结 1.Array转List，通过java.util.Arrays.asList(T... a)参数是可变泛型参数 注意，Arrays.asList返回的类型是不可变长度的集合，底层是final修饰的泛型数组...
