Description:

Below example shows how to convert byte array to Input Stream. Create ByteArrayInputStream object by passing byte array to its constructor.


Code:
package com.java2novice.files;

import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;

public class ByteArrToInputStream {

	public static void main(String a[]){
		
		String str = "converting to input stream";
		byte[] content = str.getBytes();
		int size = content.length;
		InputStream is = null;
		byte[] b = new byte[size];
		try {
			is = new ByteArrayInputStream(content);
			is.read(b);
			System.out.println("Data Recovered: "+new String(b));
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			try{
				if(is != null) is.close();
			} catch (Exception ex){
				
			}
		}
		
	}
}

Output:
