Convert String InputStream Java

Convert String InputStream Java

In below sample java program we will convert String to InputStream. I will show you two way to convert. In first example we will use ByteArrayInputStream and second example will use Apache commons (Preferred approach):

Sample java program:

package com.javahonk;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;

import org.apache.commons.io.IOUtils;

public class ConvertStringInputStream {

	public static void main(String[] args) {

		try {
			String sampleString = "Convert String to InputStream Java";

			//Example 1: Using ByteArrayInputStream
			InputStream stream = new ByteArrayInputStream(sampleString.getBytes(StandardCharsets.UTF_8));
			String convertedString = IOUtils.toString(stream, "UTF-8");
			System.out.println("Example 1: "+convertedString);
			
			

			// Example 2: Using Apache Commons
			InputStream inputStream = IOUtils.toInputStream(sampleString, "UTF-8");
			convertedString = IOUtils.toString(inputStream, "UTF-8");
			System.out.println("Example 2: "+convertedString);
			
			
		} catch (IOException e) {
			e.printStackTrace();
		}

	}

}
