Writing File in Java

Writing a file refers to writing some data to a file. Java provides the FileWriter class, which helps write data to files.

Following are the two ways to create FileWriter class object.

FileWriter file = new FileWriter("Path/file");

//Supposing we have created a file class object as fileObj;
FileWriter file = new FileWriter(File fileObj);

writingFile.java :

import java.io.FileWriter;//importing FileWriter class

public class writingFile
{
	public static void main(String[] args) throws Exception {
		//Creating a fileWriter object with specified directory and file name;
		FileWriter writefile = new FileWriter("shiva.txt");
		
		//FileWriter writefile = new FileWriter(File fileObj);
		//we can use this if text file is created with fileOjb
		
		//writing data to file using write() method.
		writefile.write("Writing data in file is very simple task !");
		writefile.close();
		System.out.println("Writing a file successfully completed!");
		//closing file.
	}
}

Output :
Writing a file successfully completed !

Note : – When you are done writing to the file, you should close it with the close() method.
