Correct the code: 1. import java.io.File; // Import the File class import java.io.IOException; // Import the IOException class to handle errors public class CreateFile { public static void main(String[] args) { try { File myObj = File("filename.txt"); if (myObj.createNewFile() { System.out.println("File created: " + getName()); } else { System.out.println("File already exists."); } } catch (IOException) { System.out.println("An error occurred."); } } } Output: File created: filename.txt
Correct the code:
1. import java.io.File; // Import the File class
import java.io.IOException; // Import the IOException class to handle errors
public class CreateFile {
public static void main(String[] args) {
try {
File myObj = File("filename.txt");
if (myObj.createNewFile() {
System.out.println("File created: " + getName());
} else {
System.out.println("File already exists.");
}
} catch (IOException) {
System.out.println("An error occurred.");
}
}
}
Output:
File created: filename.txt
2. import java.io.File; // Import the File class
import java.io.FileNotFoundException; // Import this class to handle errors
import java.util.Scanner; // Import the Scanner class to read text files
public class ReadFile {
public static void main(String[] args) {
myObj = new File("filename.txt");
Scanner myReader = Scanner(myObj);
while (myReader.hasNextLine()) {
String data =nextLine();
System.out.println(data);
4
}
myReader.close();
catch (e) {
System.out.println("An error occurred.");
e.printStackTrace();
}
}
}
Output:
Files in Java might be tricky, but it is fun enough!
3. public class DeleteFile {
public static void main(String[] args) {
File = new File();
if (myObj.delete()) {
System.out.println("Deleted the file: " + myObj.getName());
} else {
System.out.println("Failed to delete the file.");
}
}
Output:
Deleted the file: filename.txt
