Java program to read file contents

The below Java program will read the contents from a file line by line and will print it in the screen


import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
public class ReadFromFile {
public static void main (String args[]) {

  StringBuffer sFileContents = new StringBuffer();
  try (BufferedReader br = new BufferedReader(new FileReader("C:\\myfile.txt")))
  {
   String sCurrentLine;

   while ((sCurrentLine = br.readLine()) != null) {
    sFileContents.append(sCurrentLine);
   }
  } catch (IOException ex) {
   ex.printStackTrace();
   throw ex;
  }
  System.out.println("File content is :"+sFileContents);
