Reading Note pad file

Reading char by char

public class ReadingFiles {


int read1;

 

 public static void main(String args[]) throws IOException

 {

  ReadingFiles readFile=new ReadingFiles();

  

  readFile.readCharbyChar();

 }

 public void readCharbyChar() throws IOException

 {

  File file= new File("F:\\eclipse\\Practice\\BookWriting\\src\\test\\java\\org\\book\\fileReader.txt");

 InputStream inst= new FileInputStream(file) ;

 

 while((read1=inst.read())!=-1)

 {

  System.out.println((char)read1);

 }

 }

}

Outcome-

Reading by line by line

public class ReadingFiles {

String readstr;

 

 public static void main(String args[]) throws IOException

 {

  ReadingFiles readFile=new ReadingFiles();

  

  readFile.readyLineByLine ();

 }

 public void readyLineByLine() throws IOException

 {

  FileReader fr1= new FileReader("F:\\eclipse\\Practice\\BookWriting\\src\\test\\java\\org\\book\\fileReader.txt");

  BufferedReader bufRead= new BufferedReader(fr1);

  

  //while((read1= bufRead.read())!=-1)

  while((readstr= bufRead.readLine())!=null)

  {

   System.out.println(readstr);

 }

 }

}

Output-

Reading complete text message in file.

public class ReadingFiles {
public static void main(String args[]) throws IOException
 {
  ReadingFiles readFile=new ReadingFiles();
  
  readFile.readFileText();
 }
  
 public void readFileText() throws IOException
 {
  
  String file1=new String(Files.readAllBytes(Paths.get("F:\\eclipse\\Practice\\BookWriting\\src\\test\\java\\org\\book\\fileReader.txt")));
  System.out.println(file1);
 }
}
