Thread: Compare two files PDF and summaries in Java

I am new in Java, I have written code to compare two files of data in Java but that is only working for 1 line not for all lines or whole file. Below is my code:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class CompareTextFiles {

public static void main(String[] args) throws IOException {
BufferedReader reader1 = new BufferedReader(new FileReader("D:/Data/file1.docx"));
BufferedReader reader2 = new BufferedReader(new FileReader("D:/Data/file2.docx"));
String line1 = reader1.readLine();
String line2 = reader2.readLine();
boolean areEqual = true;
int lineNum = 1;
while (line1 != null || line2 != null) {
if (line1 == null || line2 == null) {
areEqual = false;
break;
} else if (!line1.equalsIgnoreCase(line2)) {
areEqual = false;
break;
}
line1 = reader1.readLine();
line2 = reader2.readLine();
lineNum++;
}
if (areEqual) {
System.out.println("Two files have same content.");
} else {
System.out.println("Two files have different content. They differ at line " + lineNum);
System.out.println("File1 has " + line1 + " and File2 has " + line2 + " at line " + lineNum);
}
reader1.close();
reader2.close();
}
}
