Write to a File

To write in a File created, we use FileWriter class together with the write() method to write some text into the file. Note that once we are done with writing in the file, you should close it with the close() method.

Example

package practices;
 
import java.io.FileWriter;
import java.io.IOException;
 
public class WriteToFile {
       public static void main(String args[]){
              try {
                     FileWriter filewriter = new FileWriter("filename.txt");
                     filewriter.write("SparkDatabox is one of the best online training institute");
                     filewriter.close(); //must close after writing to file
                     System.out.println("Successfully wrote to the file");
              } catch (IOException e) {
                     System.out.println("An erro occured");
                     e.printStackTrace();
              }
       }
}

Output

Successfully wrote to the file
