You can convert a Java String to InputStream using the ByteArrayInputStream class from the java.io package.
Example:
package org.code2care.java.examples;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
public class JavaStringToInputStreamExample {
public static void main(String[] args) throws IOException {
String inputString = "This is a input string!";
byte[] byteArr = inputString.getBytes();
InputStream inputStream = new ByteArrayInputStream(byteArr);
int nextByteData;
while ((nextByteData = inputStream.read()) != -1) {
System.out.print((char) nextByteData);
}
}
}
Note that you can also use StringBufferInputStream to achieve the same, but it has been deprecated since Java 1.1 and should be avoided.
