1. UsingByteArrayInputStream UsingByteArrayInputStreamis the simplest way to createInputStreamfrom aString. Using this approach, we do not need any external dependency. Thestring.getBytes()method encodes theStringinto a sequence of bytes using the platform’s default charset. To use a different ch...
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...
InputStream source = new URL("http://pat.net/misc/foo.txt").openStream(); The canonical way to gather it to a String has always been to use a BufferedReader, e.g. BufferedReader br = new BufferedReader( new InputStreamReader( source ) ); StringBuffer text = new StringBuffer(); fo...
public String getContent(final URL url) { try { InputStream inputStream = url.openStream(); return new Scanner(inputStream).useDelimiter("\\A").next(); } catch (final Exception e) { } return ""; } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11....

How to convert an InputStream to a stringBrian L. Gorman
3. ConvertingInputStreamto Base64 String Java has built-in support for Base64 encoding and decoding in thejava.util.Base64class. So we’ll be using thestaticmethods from there to do the heavy lifting. Base64.encode()method expects abytearray, and our image is in a file. Therefore, we ...
针对你提出的java.sql.SQLException: Cannot convert string异常问题,我将从异常信息的分析、可能的原因、解决方案以及代码示例等方面进行详细解答。 1. 确认异常的完整信息和上下文 从提供的异常信息来看,这是一个在数据库操作中常见的类型转换错误。异常信息中提到了无法将字符串'\xAC\xED\x00\x05sr...'从二进制...
Stream<String> stringStream = scanner.findAll(".+") .map(MatchResult::group); String result = stringStream.collect(Collectors.joining()); assertEquals("HelloWorldThisisatest", result); } } In this approach, we initialize aScannerobject with theInputStreamand configure it to use UTF-8 encoding...
1. UsingInputStream.readAllBytes()(Since Java 9) TheInputStream.readAllBytes()API converts the input stream to bytes. Then we use thenew String()to create a newStringobject. InputStreamin=newFileInputStream(newFile("C:/temp/test.txt"));StringfileContent=newString(in.readAllBytes()); ...
