Java: Read from a file

Read line by line using Scanner.

public static void scannerReader(String filepath)
{
    File text = new File(filepath);
    Scanner scnr;
	try {
		scnr = new Scanner(text);
        while(scnr.hasNextLine()){
            String line = scnr.nextLine();
            System.out.println(line);
        } 
	} catch (Exception e) {
		e.printStackTrace();
	}
}

Read line by line using FileInputStream, DataInputStream, InputStreamReader and BufferedReader.

public static void streamReader(String filepath)
{
	  try{
		  
		  FileInputStream fstream = new FileInputStream(filepath);
		  DataInputStream in = new DataInputStream(fstream);
		  BufferedReader br = new BufferedReader(new InputStreamReader(in));
		  String strLine;
		  while ((strLine = br.readLine()) != null)   {
			  System.out.println (strLine);
		  }
		  in.close();
		    
	  }catch (Exception e){
		  System.err.println("Error: " + e.getMessage());  
	  }
}

Read the entire file using InputStream.

public static String readAll(String filepath)
{   
    File theFile = new File(filepath);
    byte[] bytes = new byte[(int) theFile.length()];
    InputStream in;
    try {

        in = new FileInputStream(theFile);
        in.read(bytes);
        in.close();   

    } catch (Exception e) {
        e.printStackTrace();
    }

    return new String(bytes); 
}
