将文件读入arraylist，然后打印输出

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

        while (scanner.hasNextLine()) {

            lines.add(line);
        }
        scanner.close();
    } catch (FileNotFoundException e) {
        System.out.println("文件未找到：" + filePath);
    }
    return lines;
}
