It says Process Finished but there is no output-CodePudding

I'm new to java and I'm having a little problem with my code. There's no error and such, it just keeps saying process finished but no output was displayed. The filename is correct as I've checked.

import java.nio.file.; import java.io.;

public class GuessingGame {
    public GuessingGame() {
        String filename = "C:\\Users\\angela\\Documents\\words.txt";
        Path path = Paths.get(filename.toString());
        
        try {
            InputStream input = Files.newInputStream(path);
            BufferedReader read = new BufferedReader(new InputStreamReader(input));
            
            String word = null;
            while((word = read.readLine()) !=null) {
                System.out.println(word);
            }
        }
        catch(IOException ex) {
            
        }
    }
    public static void main (String[] args) {
        new GuessingGame();
    }
}

CodePudding user response：

You are ignoring the exception and you don't close the file. Save some typing by using the built-in input.transferTo() for copying the file to System.out, and pass on the exception for the caller to handle by adding throws IOException to constructor and main.

Replace your try-catch block with this try-with-resources, which handles closing the file after use:

try (InputStream input = Files.newInputStream(path)) {
    input.transferTo(System.out) ;
}

You managed to call the intended class, but you also needed to specify the specific function which you have declared in the function. Like so: public static void main (String[] args) { GuessingGame gg = new GuessingGame; gg.GuessingGame(); }
