If you want to convert a String into InputStream, you can use the following piece of code.

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;

public class ConvertStringToInputStream {

	public static void main(String[] args) {
		try {
			// Convert the String into InputStream 
			String eurekaUrl = "https://ykyuen.wordpress.com";
			InputStream is = new ByteArrayInputStream(eurekaUrl.getBytes("UTF-8"));
			
			// Use Apache Commons IO to get the content of the InputStream
			System.out.println(IOUtils.toString(is, "UTF-8")); 
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

Don’t forget to add the commons-io dependency in the pom.xml.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-io</artifactId>
			<version>1.3.2</version>
		</dependency>
	</dependencies>
</project>

Done =)
