Please help. I need to fix for third requirement. What is wrong with my code? "Available" does not throw nullPointerException when I run by the way.
package com.codegym.task.task09.task0929;
import java.io.*;
/*
Let's make the code do something useful!
*/
public class Solution {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String sourceFileName = reader.readLine();
String destinationFileName = reader.readLine();
InputStream fileInputStream = null;
try {
fileInputStream = getInputStream(sourceFileName);
} catch (FileNotFoundException e) {
System.out.println("File does not exist.");
sourceFileName = reader.readLine();
fileInputStream = getInputStream(sourceFileName);
}
finally {
OutputStream fileOutputStream = getOutputStream(destinationFileName);
while (fileInputStream.available() > 0) {
int data = fileInputStream.read();
fileOutputStream.write(data);
}
fileInputStream.close();
fileOutputStream.close();
}
}
public static InputStream getInputStream(String fileName) throws IOException {
return new FileInputStream(fileName);
}
public static OutputStream getOutputStream(String fileName) throws IOException {
return new FileOutputStream(fileName);
}
}
