Here you will find how to convert string into java.io.InputStream object using java.io.ByteArrayInputStream class. package org.kodejava.io; import java.io.*; import java.nio.charset.StandardCharsets; public class StringToStream { public static void main(String[] args) { String text = "Converting String to InputStream Example"; // Convert String to InputStream using ByteArrayInputStream // class. This class constructor takes the string byte array […]
