Please Help...

Use the AdapterFileOutputStream class to adapt FileOutputStream to the new AmigoStringWriter interface.

Requirements:

AmigoStringWriter must be an interface.
The AdapterFileOutputStream class must implement the AmigoStringWriter interface.
The AdapterFileOutputStream class must have a private FileOutputStream field called fileOutputStream.
The AdapterFileOutputStream class must have a constructor with a FileOutputStream parameter.
The AdapterFileOutputStream class's flush() method must delegate the call to fileOutputStream.
The AdapterFileOutputStream class's writeString(String s) method must delegate the call to the fileOutputStream field's corresponding write() method.
The AdapterFileOutputStream class's close() method must delegate the call to fileOutputStream.

package com.codegym.task.task19.task1902; /* Adapter */ import java.io.FileOutputStream; public class AdapterFileOutputStream implements AmigoStringWriter{ private FileOutputStream fileOutputStream; AdapterFileOutputStream(FileOutputStream fileOutputStream){ this.fileOutputStream = fileOutputStream; } public void flush(){ } public void writeString(String h){ } public void close(){ } public static void main(String[] args) { } }

I Have Solved It Using This Code

package com.codegym.task.task19.task1902;

/*
Adapter

*/

import java.io.*;

public class AdapterFileOutputStream implements AmigoStringWriter{
    private FileOutputStream fileOutputStream;
    AdapterFileOutputStream(FileOutputStream fileOutputStream){
        this.fileOutputStream = fileOutputStream;
    }
    public void flush() throws IOException {
        fileOutputStream.flush();
    }
    public void writeString(String s) throws IOException {
        byte[] strToBytes = s.getBytes();
        fileOutputStream.write(strToBytes);
    }
    public void close() throws IOException {

        fileOutputStream.close();
    }
    public static void main(String[] args) {

    }


}
