下面是将Java byte array转换为string的步骤: erDiagram Byte_Array -->|转换为|string| String 3. 代码实现 步骤1:创建一个byte数组 首先,你需要创建一个byte数组,用于存储数据。 byte[]byteArray={97,98,99,100,101,102}; 1. 步骤2:将byte数组转换为String 接下来,使用String类的构造函数将byte数组转换...
To create a String from byte array in Java, create a new String object with String() constructor and pass the byte array as argument to the constructor. In the following example, we will take a byte array{65, 66, 67, 68}and create a new stringstrfrom this byte array. Java Program <...
public static String byteArrayToStr(byte[] byteArray) { if (byteArray == null) { return null; } String str = new String(byteArray); return str; } 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了如下代码所示的构造方法。需要注...
1.将基本数据类型,如int, long, double, 及String类型数据写入到 byte[]中, 2.从byte[]中将数据读取到 int, long, double, 及String类型变量中 packagecom.machuang.io.others;importjava.io.BufferedInputStream;importjava.io.BufferedOutputStream;importjava.io.ByteArrayInputStream;importjava.io.ByteArrayOutpu...

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 8 Base64.getDecoder()....
Allocates a new String constructed from a subarray of an array of 8-bit integer values. The offset argument is the index of the first byte of the subarray, and the count argument specifies the length of the subarray. Each byte in the subarray is converted to a char as specified in ...
import java.nio.charset.Charset; public class Main { public static void main(String[] args) { try { String str1 = “Udemy online courses”; System.out.println(“string1 = ” + str1); // copy the contents of the String to a byte array byte[] arr = str1.getBytes(Charset.forName(...
// []byte to string s2 := string(b) 强转换 通过unsafe和reflect包,可以实现另外一种转换方式,我们将之称为强转换(也常常被人称作黑魔法)。 func String2Bytes(s string) []byte { sh := (*reflect.StringHeader)(unsafe.Pointer(&s)) bh := reflect.SliceHeader{ ...
