I have the following java program called MultiBufferedWriter
import java.io.BufferedWriter;
import java.io.FileWriter;import java.util.ArrayList;import java.io.IOException;import java.util.Scanner;
public class MultiBufferedWriter{
private ArrayList<BufferedWriter> writers;
private int currentFile; public MultiBufferedWriter(String filePattern, int n) throws IOException {
this.currentFile = 0;
ArrayList<BufferedWriter> dog = new ArrayList<BufferedWriter>(); writers = dog; for(int i = 0; i < n; i++) { BufferedWriter out = new BufferedWriter(new FileWriter(filePattern+(i+1)));writers.add(out); }}
public void write(String mouse) throws IOException
{
for(int i = 0; i < writers.size(); i++){writers.get(currentFile).write(mouse);
currentFile++;
}
currentFile = 0;
}
public void close() throws IOException
{
for(int i = 0; i < writers.size(); i++)
{
writers.get(i).close();
}
}
public void newLine() throws IOException
{
for(int i = 0; i < writers.size();i++)
{
writers.get(currentFile).newLine();
}
}
}

How do i write a method partitionFile which takes as input a String souce a String destination and an int n. Using the class MultiBufferedWriter( which i have written out already and it compiles) it should partition the source file into several files with the pattern destination + i for ranges of i to 1 until n.
