To create a new file and write text on it. We can write to a file using Java in different ways but I show you how to write text to a file using BufferedWriter.

package classOneGeneral;

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

public class WriteToFile {

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

		String textToWrite = "I am learning Java from SoftwareTestingMaterial";
		// Import BufferedWriter and FileWriter classes
		/* BufferedWriter writes text to a character-output stream, buffering characters 
		so as to provide for the efficient writing of single characters, arrays, and strings. */
		//Import FileWriter and BufferedWriter class
		BufferedWriter writer = new BufferedWriter(new FileWriter("D:\\WriteToFile.txt"));
		writer.write(textToWrite);
	    // Close the BufferedWriter object to prevent memory leak
		writer.close();
	}
}

package classOneGeneral;

import java.io.BufferedWriter;

import java.io.FileWriter;

import java.io.IOException;

public class WriteToFile {

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

String textToWrite = "I am learning Java from SoftwareTestingMaterial";

// Import BufferedWriter and FileWriter classes

/* BufferedWriter writes text to a character-output stream, buffering characters

so as to provide for the efficient writing of single characters, arrays, and strings. */

//Import FileWriter and BufferedWriter class

BufferedWriter writer = new BufferedWriter(new FileWriter("D:\\WriteToFile.txt"));

writer.write(textToWrite);

// Close the BufferedWriter object to prevent memory leak

writer.close();

}
