Note:- Please study than type and execute this java code and also give output for this java
![Examples
For examples 1 to 4, you must create the data files with a text tool, such as
Notepad
exampleOne
This program reads data
from a physical file,
create a reference to the file,
perform a computation,
display the result,
close the file
package chario:
import java.utilScanner:
import java.io.*:
//
public class Chario {
//
public static void main(String[] args) throws IQException
{
File filel = new File("fileOne.txt"); //Create a reference to the physical file
/*
Use Notepad to create a text file named fileOne.txt
which must be in the same directory that src is in
To find src, open your project in NetBeans and hover its name, which is in
the top left just below the Projects menu; this will display the path to your
project
My project path is, yours will be different
I:\\Ajava\161\WPPractice\IO\charstream\chario
My fileOne.txt is located in chario
