The following example demonstrates using the file.exists() method of the File class to detect whether a file exists:
/*
author by w3cschool.cc
Main.java
*/import java.io.File;public class Main {
public static void main(String[] args) {
File file = new File("C:/java.txt");
System.out.println(file.exists());
}}The output result of running the above code is (if it exists in your C drive File java.txt):
true
The above is the Java example - detecting whether the file exists. For more related content, please pay attention to the PHP Chinese website (m.sbmmt.com)!
