Java Exercises: Check if a file or directory has read and write permission

Java Input-Output: Exercise-4 with Solution

Write a Java program to check if a file or directory has read and write permission.

Sample Solution:

Java Code:

import java.io.File;
public class Exercise4 {
       public static void main(String[] args) {
        // Create a File object
        File my_file_dir = new File("/home/students/abc.txt");
         if (my_file_dir.canWrite()) 
           {
            System.out.println(my_file_dir.getAbsolutePath() + " can write.\n");
           } 
         else
          {
            System.out.println(my_file_dir.getAbsolutePath() + " cannot write.\n");
          }
         if (my_file_dir.canRead()) 
           {
            System.out.println(my_file_dir.getAbsolutePath() + " can read.\n");
           } 
         else
          {
            System.out.println(my_file_dir.getAbsolutePath() + " cannot read.\n");
          }  
      }
  }
  

Sample Output:

/home/students/abc.txt can write.                                                                                    
/home/students/abc.txt can read.
