How To Create And Write And Delete Txt File Using Java NetBeans
In this Java tutorial will demonstrate how to create a text file with a custom name and write data from a jTextArea into the file. Additionally, we will learn how to remove the file using the FileWriter and BufferedWriter classes in Java NetBeans, all in a step-by-step manner .
Project Source Code:
// create and write in text file
private void jButtonCreateAndWriteActionPerformed(java.awt.event.ActionEvent evt) {
String filePath = jTextFieldFilePath.getText();
File file = new File(filePath);
if(!file.exists()){
try {
file.createNewFile();
FileWriter wr = new FileWriter(file);
BufferedWriter bw = new BufferedWriter(wr);
bw.write(jTextArea1.getText());
bw.close();
wr.close();
} catch (IOException ex) {
Logger.getLogger(TxtFile_Create_Write_Delete.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
// delete file
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String filePath = jTextFieldFilePath.getText();
