下面是一个示例代码,将Base64编码后的字符串转换为普通字符串: importjava.util.Base64;publicclassBase64StringConversion{publicstaticvoidmain(String[]args){Stringbase64String="SGVsbG8sIFdvcmxkIQ==";byte[]decodedBytes=Base64.getDecoder().decode(base64String);StringdecodedString=newString(decodedBytes);...
步骤1:导入Base64类库 在Java中使用Base64需要导入相应的类库,可以使用以下代码: importjava.util.Base64; 1. 步骤2:将Base64字符串解码 使用Base64类的decode方法将Base64字符串解码为字节数组,代码如下: byte[]decodedBytes=Base64.getDecoder().decode(base64String); 1. 这里base64String是待解码的Base64字符...
