public boolean isAbsolute()

Parameters

NA

Return Value

The method returns true if this abstract pathname is absolute, else the method returns false.

Exception

NA

Example 1

The following example shows the usage of Java File isAbsolute() method. We've created two File references. Then we're creating a File Object using test.txt which is not present in the current directory. Then we've created the file using createNewFile() method. Now using getAbsoluteFile() method, we're getting the file and checking the absolute path of file using isAbsolute() method and printing it.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      File f1 = null;      
      try {
         
         // create new files
         f = new File("test.txt");
         
         // create new file in the system
         f.createNewFile();
         
         // create new file object from the absolute path
         f1 = f.getAbsoluteFile();
         
         // prints the file path if is absolute
         System.out.print("Is absolute path: "+ f1.isAbsolute());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Is absolute path: true

Example 2

The following example shows the usage of Java File isAbsolute() method. We've created a File reference. Then we're creating a File Object using F:/test.txt which is present in the provided directory. Now using getAbsoluteFile() method, we're getting the file and printing path status as absolute using isAbsolute() method.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;      
      try {
         
         // create new files
         f = new File("F:/test.txt");         
    
         // get the file
         File f1 = f.getAbsoluteFile();
         
         // prints the file path as is absolute
         System.out.println("Is absolute: "+f1.isAbsolute());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Is absolute: true

Example 3

The following example shows the usage of Java File isAbsolute() method. We've created a File reference. Then we're creating a File Object using F:/test directory which is present in the provided location. Now using getAbsoluteFile() method, we're getting the directory and its absolute path status using isAbsolute() method.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;      
      try {
         
         // create new files
         f = new File("F:/test");         
    
         // get the file
         File f1 = f.getAbsoluteFile();
         
         // prints the file path status
         System.out.println("Is absolute: "+f1.isAbsolute());
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Is absolute: true
