This is an example of how to get the size of a File in bytes. We are using the File class that is an abstract representation of file and directory pathnames. Getting the size of a File implies that you should:
- Create a new File instance by converting the given pathname string into an abstract pathname.
- Use the
length()API method of File. This method returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core;
import java.io.File;
public class GetSizeOfFileInBytes {
public static void main(String[] args) {
File file = new File("C://file.txt");
// Returns the length of the file denoted by this abstract pathname.
// The return value is unspecified if this pathname denotes a directory.
long size = file.length();
System.out.println("File size in bytes is: " + size);
}
}
This was an example of how to get the size of a File in bytes in Java.
