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...
importcom.google.protobuf.ByteString;publicclassStringToByteArrayExample{publicstaticvoidmain(String[]args){Stringstr="Hello";ByteStringbyteString=ByteString.copyFromUtf8(str);byte[]byteArray=byteString.toByteArray();for(byteb:byteArray){System.out.print(b+" ");// 输出 "72 101 108 108 111"...
importjava.io.*;publicclassByteStreamTest{publicstaticvoidmain(Stringargs[])throwsIOException{ByteArrayOutputStreambOutput=newByteArrayOutputStream(12);while(bOutput.size()!=10){//获取用户输入bOutput.write(System.in.read());}byteb[]=bOutput.toByteArray();System.out.println("Print the content")...
byte[] bytes = string.getBytes(); //Convert back to String String s = new String(bytes); //Check converted string against original String System.out.println("Decoded String : " + s); } } 输出: hello world 通过Base64 将String转换成byte[]或者byte[]转换成String[Java 8] 可能你已经了解 ...
接下来分析一下常规的byte[]转为String的方法,代码如下: publicstaticStringbyteArrayToStr(byte[] byteArray){if(byteArray ==null) {returnnull; }Stringstr=newString(byteArray);returnstr; } 很简单,就是String的构造方法之一。那我们分析Java中String的源码,可以看出所有以byte[]为参数的构造方法最终都调用...

String.getBytes() method To convert from string to byte array, use String.getBytes() method. Please note that this method uses the platform’s default charset. //String String string = "Java Tutorials"; //Convert string to byte[] byte[] bytes = string.getBytes(); Base64 class in Java ...
ToArray<T>() (Inherited from Object) ToByteArray() Creates a newly allocated byte array. ToString() Returns a string representation of the object. (Inherited from Object) ToString(Charset) Converts the buffer's contents into a string by decoding the bytes using the specified java.nio....
To convert a byte array to a String in Java, we can use the String class’s constructor that takes a byte array as an argument. Here’s an example: byte[]byteArray={65,66,67,68,69};Stringstr=newString(byteArray);System.out.println(str); ...
