Converting a string of binary to data, to save to a file

[Rybo]

Hello everyone. Recently, I've been working on the task of converting a file to a string of binary, converting that string of binary to a sound, and then converting that back to a string of binary. The problem is, after I convert back to binary, I can't figure out how to convert that binary string to data so I can save it to a file, and re-create the file. The reason I'm not posting and code for this post is I literally have no idea on how to go about saving a string of binary to a file. I did a good 20 minutes of searching and came up with no results for this issue. Any help would be very appreciated.
Ex, if I had

101010011001011110011111010011000111000011100001110000111000011100001110000111000011100001110000111000011100001110000111001011001011001011001011001011001011001011001011001011001011001011001011001011
0001110001110001110001110001110001110001110001110001110001

As a string, how would I convert that string of binary into the original file?

Use obJectOutputStream

As a string, how would I convert that string of binary into the original file?

That depends on the content of the original file, i.e. if the original content were a bunch of ints, I'd break up the String into 32 bit chunks and convert each to an int; but it all depends on the way the original file was encoded into a binary String ...

kind regards,

Sample Code of Dealing with binary file

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.util.Date;

public class ObjectIOApp {
public static void main(String args[]) throws IOException, ClassNotFoundException {
File file = new File("test.txt");
FileOutputStream outFile = new FileOutputStream(file);
ObjectOutputStream outStream = new ObjectOutputStream(outFile);
TestClass1 t1 = new TestClass1(true, 9, 'A', 0.0001, "java");
TestClass2 t2 = new TestClass2();
String t3 = "This is a test.";
Date t4 = new Date();
outStream.writeObject(t1);
outStream.writeObject(t2);
outStream.writeObject(t3);
outStream.writeObject(t4);
outStream.close();
outFile.close();
FileInputStream inFile = new FileInputStream(file);
ObjectInputStream inStream = new ObjectInputStream(inFile);
System.out.println(inStream.readObject());
System.out.println(inStream.readObject());
System.out.println(inStream.readObject());
System.out.println(inStream.readObject());
inStream.close();
inFile.close();
file.delete();
}
}
