Writing Text file Using Java Steps

1. Create a new Java Class and name it what you want.

2. Insert the following import above your Class.

[java]import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;[/java]

3. Inside your main method, declare the following variables. Declare a scanner, string, and Buffer Writer variables.

[java]//scanner
Scanner input = new Scanner(System.in);
//the file to write
String fileName;
//buffer writer
BufferedWriter bWriter=null;[/java]

4. Insert the following statement for user input

[java]System.out.print(“Enter file name: “);
fileName = input.nextLine();[/java]

5. After step 4, insert the following codes below for writing the file.

[java]try{
//encoding
FileWriter fWriter = new FileWriter(fileName + “.txt”);
//file writer
bWriter = new BufferedWriter(fWriter);
//character to write
bWriter.write(“Marjohn I. Bebeloni”);
bWriter.newLine();
bWriter.write(“Tindalo St., Sainz, City of Mati”);
System.out.println(“The file name ” + fileName + ” is created!”);
}catch(IOException ex){
System.out.println(“Error writing the file”);
}finally{
//close the writer
try{
if (bWriter != null){
bWriter.close();
}
}catch(IOException e){
}
}[/java]

6. The output should look like the image below.

7. Complete Source Code of Writing Text file using Java

[java]import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;
public class FileWriting {
public static void main(String arg[]){
//scanner
Scanner input = new Scanner(System.in);
//the file to write
String fileName;
//buffer writer
BufferedWriter bWriter=null;

System.out.print(“Enter file name: “);
fileName = input.nextLine();

try{
//encoding
FileWriter fWriter = new FileWriter(fileName + “.txt”);
//file writer
bWriter = new BufferedWriter(fWriter);
//character to write
bWriter.write(“Marjohn I. Bebeloni”);
bWriter.newLine();
bWriter.write(“Tindalo St., Sainz, City of Mati”);
System.out.println(“The file name ” + fileName + ” is created!”);
}catch(IOException ex){
System.out.println(“Error writing the file”);
}finally{
//close the writer
try{
if (bWriter != null){
bWriter.close();
}
}catch(IOException e){
}
}
}
}[/java]
