然后,它调用 FromBase64String(String) 方法来解码 UUencoded 字符串,并调用 BitConverter.ToInt32 方法将每组四个字节(32 位整数的大小)转换为整数。 该示例的输出显示原始数组已成功还原。 C# 复制 运行 using System; public class Example { public static void Main() { // Define an array of 20 ...
public static void main(String[] args) { String original = "Hello, VG!"; byte[] encoded = Base64.getEncoder().encode(original.getBytes(StandardCharsets.UTF_8)); System.out.println("Encoded: " + new String(encoded, StandardCharsets.UTF_8)); byte[] decoded = Base64.getDecoder().decod...
下面是使用Base64.encodeBase64String方法进行Base64编码的示例代码: importorg.apache.commons.codec.binary.Base64;publicclassBase64Example{publicstaticvoidmain(String[]args){// 待编码的字符串StringoriginalString="Hello, Base64!";// 转换为字节数组byte[]originalBytes=originalString.getBytes();// 使用Base...

Converts the specified string, which encodes binary data as base-64 digits, to an equivalent 8-bit unsigned integer array.
用String.getBytes()方法将字符串转换为byte数组,通过String构造函数将byte数组转换成String 注意:这种方式使用平台默认字符集 package com.bill.example;publicclassStringByteArrayExamples{publicstaticvoidmain(String[] args) {//Original StringStringstring="hello world";//Convert to byte[]byte[] bytes =string...
