Hey You just forgot to close the writer .
Here is the modified code

Code:

package javaapplication1;
import java.net.*;
import java.io.*;
import java.nio.channels.FileChannel;
import java.lang.String;
import java.nio.ByteBuffer;

public class Test {
    
    
    public static void main(String[] args) throws Exception {
        
        File aFile = new File("C:\\Java\\First1.text");
        setcontents(aFile,getcontent());
    }
    
    static public StringBuffer getcontent() {
        StringBuffer contents = new StringBuffer();
        String text[];
        try{
            URL yahoo = new URL("http://www.yahoo.com");
            URLConnection yc = yahoo.openConnection();
            BufferedReader in = new BufferedReader(
                    new InputStreamReader(
                    yc.getInputStream()));
            
            String line;
            while (( line = in.readLine()) != null) {
                contents.append(line);
                contents.append(System.getProperty("line.separator "));
                
            }
        } catch(IOException e){
            e.printStackTrace();
        }
        return contents;
    }
    
    
    static public void setcontents(File afile,StringBuffer acontents) {
        Writer output=null;
        try{
            System.out.println(acontents.toString());
            output=new BufferedWriter(new FileWriter(afile));
            output.write(acontents.toString());
            output.close();// This line I added
        } catch(IOException e){
            e.printStackTrace();
        }
    }
    
    
}

I made some modifications to make it working in my machine dont look at that , Only one line I think is important. i.e "output.close()"
