Example: Convert InputStream to String import java.io.*; public class InputStreamString { public static void main(String[] args) throws IOException { InputStream stream = new ByteArrayInputStream("Hello there!".getBytes()); StringBuilder sb = new StringBuilder(); String line; BufferedReader br...
One effective way to convert anInputStreamto aStream<String>is by using aBufferedReaderalong with itslines()method. First, we’ll define abytearraybytescontaining a sequence of text lines: byte[] bytes = "Hello\nWorld\nThis\nis\na\ntest".getBytes(StandardCharsets.UTF_8); ...
private byte[] convertIoCharset(byte[] fileBytes) { Assert.notNull(fileBytes, "远程获取文件流为空,文件转换终止"); try (InputStream inputStream = new ByteArrayInputStream(fileBytes); Reader reader = new BufferedReader(new InputStreamReader(inputStream, Charset.forName(FileEncodeUtil.getJavaEncode...
2. Convert Using Java First – let's look atthe Java solution: @TestpublicvoidgivenUsingPlainJava_whenConvertingByteArrayToInputStream_thenCorrect()throwsIOException {byte[] initialArray = {0,1,2};InputStreamtargetStream=newByteArrayInputStream(initialArray); } ...

在JAVA中,将附件对象转换为ByteArray可以通过以下步骤实现: 1. 首先,需要使用Java的文件处理类来读取附件文件。可以使用`FileInputStream`类来读取文件内容。例如,假设...
当我们需要处理原始二进制数据时,将InputStream转换为字节数组是一个有效的方案。下面是相关代码示例: importjava.io.ByteArrayOutputStream;importjava.io.IOException;importjava.io.InputStream;publicclassInputStreamToByteArray{publicstaticbyte[]convert(InputStreaminputStream)throwsIOException{ByteArrayOutputStreambyte...
