exists( ) method is used to find out whether the file or folder exists at the path that is provided in File Class object creation statement as shown in the below example -
File file1 = new File("fileX.txt");
File folder1 = new File("ABZ");
System.out.println("A file with 'fileX.txt' name exists in your workspace");
System.out.println("A folder with 'ABZ' name exists in your workspace");
Lets implement this on Eclipse IDE -
1. Launch Eclipse IDE, create a new Java Class 'ExistsDemo.java' with main( ) method as shown below -
2. Lets go to our workspace location of our Program to find the existing file 'fileX.txt' and folder 'ABZ' as shown below -
3. Lets create a File Class objects for the above file and folder as shown below (Resolve any import errors) -
4. Check whether the file and Folder exists in our Project Workspace using exists( ) method and printing that they are available in our Project Workspace when exists( ) method gives true as a results as shown below -
5. Save & Run the Java Class 'ExistsDemo.java' and observe that the statements will get printed as both the file and folder are available in our project workspace as shown below -
Hence exists( ) methods returns the boolean value true when the file or folder is available in the specified path of the File Class object creation statement. Else exists( ) will return false boolean value.
