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...
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....
In the example above,we create aBufferedReaderobject wrapped around theInputStreamusing anInputStreamReader. This allows us to read lines of text efficiently from theInputStream.Additionally, thelines()method of theBufferedReaderreturns aStream<String>containing the lines read from the input. Lastly,...
new DataInputStream( source ).readFully( buf ); String text = new String( buf ); That would be a bit less typing and involve only an array and a class. The problem is that it relies on the input stream's available() method to reflect the total size of the data to be returned.....
Java——Read/convert an InputStream to a String 获取InputStream 并将其转换为String的简单方法。 添加commons-io-2.4.jar import java.io.IOException; import java.io.InputStream; import org.apache.commons.io.IOUtils;publicclassStringFromFile {publicstaticvoidmain(String[] args) throws IOException {...
public static void main(String[] args) { // new object MySerialization mySerialization = new MySerialization(99); try { // write object to file test-serial-obj ObjectOutputStream objOut = new ObjectOutputStream(new FileOutputStream("./test-serial-obj")); ...
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 ...
How do I convert an InputStream to a string in Java?Brian L. Gorman
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()); ...
