java - 从文本文件添加并忽略语法错误

Question

我正在编写一个代码，将文本文件中的数字相加并显示总数。但我想让它这样，如果用户输入一个单词或一个十进制数字，那么它会忽略它并继续添加下一个数字？

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

public class Task1 {
    public static void main(String [] args) throws FileNotFoundException {
        File myFile = new File("Numbers.txt");         
        Scanner scan = new Scanner(myFile);

        int sum=0;        

        while (scan.hasNext()) {         
            sum+= scan.nextInt( );     
        } 
        System.out.println(sum);

        scan.close();

    }
}

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

public class Task1 {
    public static void main(String [] args) throws FileNotFoundException {
        File myFile = new File("Numbers.txt");         
        Scanner scan = new Scanner(myFile);

        String sum="";        
        int number = 0;
        int total = 0;
        while (scan.hasNext()) { 
            try {
              sum = scan.next();
              number = Integer.parseInt(sum);        
              total += number;
            } catch(Exception e) {
               System.out.println("Unable to parse string !! + " + sum);
            }
        } 
        System.out.println("The total is : " + total);

        scan.close();

    }
}
