File getTotalSpace() method in Java with examples

The getTotalSpace() function is a part of File class in Java . This function returns the total size of the partition denoted by the abstract pathname, if the pathname does not exist then it returns 0L.

Function signature:

public long getTotalSpace()

Syntax:

long var = file.getTotalSpace();

Parameters: This method does not accept any parameter.

Return Value: The function returns long data type represents size of the partition in bytes

Exception: This method throws SecurityException if the method does not allow file to be created

Below programs illustrates the use of getTotalSpace() function:

Example 1: The file “F:\\program.txt” is a existing file in F: Directory .

// Java program to demonstrate 
// getTotalSpace() method of File Class 

import java.io.*; 

public class solution { 

    public static void main(String args[]) 

    { 

        // Create an abstract pathname (File object) 

        File f = new File("F:\\program.txt"); 

        // Display the Total size of the partition 

        // using the getTotalSpace() function 

        System.out.println("Total Space: "

                           + f.getTotalSpace()); 

    } 
}

Output:

Total Space: 355947507712

Example 2: The file “F:\\program1.txt” does not exist file in F: Directory .

// Java program to demonstrate 
// getTotalSpace() method of File Class 

import java.io.*; 

public class solution { 

    public static void main(String args[]) 

    { 

        // Create an abstract pathname (File object) 

        File f = new File("F:\\program1.txt"); 

        // Display the Total size of the partition 

        // using the getTotalSpace() function 

        System.out.println("Total Space: "

                           + f.getTotalSpace()); 

    }
