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());
    }
}

Output:

Total Space: 0
