i am comparing two text file by checking occurance of a line in file 1 by comparing it with each line in file 2(not line by line)
i have to print in 3rd text file as difference
please see my progrm and tell me modification required
package comp.vnet.comparator;
import java.io.*;
import comp.vnet.comparator.NewFile;
class FileComparator {
public static void main(String[] args) throws IOException{
String file1,file2,String1,String2;
BufferedReader br1,br2;
int fileCount1=0;
int fileCount2=0;
br1= new BufferedReader(new InputStreamReader (System.in));
// File file = new File ("output.txt");
FileWriter fstream = new FileWriter("out.txt");
// FileOutputStream fo = new FileOutputStream("E:/Filecomparator/FileComparator/output.txt");
System.out.println("Enter First file name");
file1="b.txt";
//file1=br1.readLine();
System.out.println("Enter Second file name");
file2="a.txt";
//file2=br2.readLine();
NewFile nf= new NewFile();
br1=nf.creatingFile(file1);
br2=nf.creatingFile(file2);
while ((String1= br1.readLine()) != null) {
fileCount1++;
}
while ((String2= br2.readLine()) != null) {
fileCount2++;
}
System.out.println("fileCount1+ : " + fileCount1);
System.out.println("fileCount2+ : " + fileCount1);
br1=nf.creatingFile(file1);
BufferedWriter out = new BufferedWriter(fstream);
for(int i=0;i<=fileCount1;i++)
{
br2=nf.creatingFile(file2);
String1=br1.readLine();
for(int j=0;j<fileCount2;j++)
{
String2=br2.readLine();
if ( String1.equals (String2) ) {
System.out.println("the line is equal");
}
else{
out.write(String1);
System.out.println(String1);
}
}
}
out.close();
br1.close();
br2.close();
}
