JAVA SP T


Lets dive into snapshot of my programs!💻

3.Write a Java program to create a method that reads a file and throws an exception if the file is not found

💡Code:

import java.io.File;
              import java.io.FileNotFoundException;
              import java.util.Scanner;
               
              class Read_File {
                public static void main(String x[] ) {
                  try {
                    r_File("test2.txt");
                  } catch (FileNotFoundException e) {
                    System.out.println("Exception: " + e.getMessage());
                  }
                }
              
                public static void r_File(String fname) throws FileNotFoundException {
                  File file = new File(fname);
                  Scanner scanner = new Scanner(file);
              
              
                  while (scanner.hasNextLine()) {
                    String line = scanner.nextLine();
                    System.out.println(line);
                  }
              
                  scanner.close();
                }
              }
