FILE IN JAVA
File is the most important part of any application.
Java has methods for creating, reading, updating, and deleting the files.
A file is a named location that can be used to store related information. Like main.java is a Java file that contains information about the Java program.
The File class from the java.io package, allows us to work with files.
Syntax:
import java.io.File;
File myObj = new File("filename.txt");
Example:
import java.io.*;
public class FileDemo
{
public static void main(String[] args)
{
try
{
File file = new File("javaFile123.txt");
if (file.createNewFile())
{
System.out.println("New File is created!");
}
else
{
System.out.println("File already exists.");
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
Output:
New File is created!
