如何将file方法内的二维数组改为一维数组 并且 返回这个一维数组 存入到主方法内的Number数组

import java.util.*;
import java.io.*;
public class a5 {
    public static void main(String[] args) {
                int Number[ ] = new int [100];        
                file("D:\\a.txt");
        }
        public void file(String file) {
        List<String[]> data = new ArrayList<>();
        try {
            Scanner in = new Scanner(new File(file));
            while (in.hasNextLine()) {
                String str = in.nextLine();
                data.add(str.split(" ,|"));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        // list转化为数组
        String[][] result = data.toArray(new String[][] {});
 
        for (String[] strings : result) {
            for (String string : strings) {
                System.out.print(string + " ");
            }
            System.out.println();
        }
    }
}

说的不是很清楚，根据你的程序修改了一下，不知道下面的合不合你的要求

import java.util.*;
import java.io.*;

public class test {
	static List<String>  list= new ArrayList<String>();
	public static void main(String[] args) {
		int Number[] = new int[100];
		file("D:\\a.txt");
		for(int i=0;i<list.size();i++) {
			Number[i]=Integer.parseInt(list.get(i));
		}
	}

	public static void  file(String file) {
		List<String[]> data = new ArrayList<>();
		try {
			Scanner in = new Scanner(new File(file));
			while (in.hasNextLine()) {
				String str = in.nextLine();
				data.add(str.split(" ,|"));
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		// list转化为数组
		String[][] result = data.toArray(new String[][] {});
		for (String[] strings : result) {
			for (String string : strings) {
			    list.add(string);
			}
		}
	}
}
