从文本文件加载数组的错误部分无法正常工作

Question

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Arrays;
import java.util.Scanner;

public class readfile{
    static int[] array1 = new int[5];
    
    public static int[] choosefile(){
    try {

        Scanner s = new Scanner(new File("input.txt"));
                                                            
        int i = 0;
        while (s.hasNext()) {
            array1[i++] = s.nextInt();
        }

        s.close();
        
        
    } catch (FileNotFoundException e) {
        System.err.println("The file does not exist!");
        
    }
    return array1;
    }
    
    readfile(int[] array1) { 
        readfile.array1 = array1;
        }
    
    void printarray() {
        System.out.println("Datas in the array");
        System.out.println(Arrays.toString(array1));
        System.out.println();
    
    }

Basically the code works if the text file exists but if it doesnt the output is like

The file does not exist, Datas in the array [0, 0, 0, 0, 0]

It says "The file does not exist." but still do other operations with an array whichs all values are 0? How can I fix it?

Answer 1

You return after the try catch . Meaning it hits the catch and then returns array1. To fix this, you can return inside the catch.

} catch (FileNotFoundException e) {
            System.err.println("The file does not exist!");
            //return here
}
