将txt文件保存到二维矩阵

Question

我是 java 编程的初学者，我不知道如何将 txt 信息保存到二维矩阵。接下来我要做的操作是转置矩阵等

我的代码：

 File text = new File("/matrix.txt");

    System.out.print("\Path to file: ");
    Scanner sc = new Scanner(System.in);
    String m = sc.nextLine();

    BufferedReader br = new BufferedReader(new FileReader("m));
    String st;

    System.out.println("matrix");

    while ((st = br.readLine()) != null)
        System.out.println(st);

输出例如：

matrix
1 0 0 0 0 1 1 
0 1 0 0 1 0 0 
0 0 1 0 1 1 1
0 0 0 1 0 0 1

我需要相同的输出，矩阵中的芽。谢谢

我试过：

Scanner sc = new Scanner(new BufferedReader(new FileReader("/matrix.txt")));
            int rows = 4;
            int columns = 7;
            int [][] myArray = new int[rows][columns];
            while(sc.hasNextLine()) {
                for (int i=0; i<myArray.length; i++) {
                    String[] line = sc.nextLine().trim().split(" ");
                    for (int j=0; j<line.length; j++) {
                        myArray[i][j] = Integer.parseInt(line[j]);
                    }
                }
            }
            System.out.println(Arrays.deepToString(myArray));

但输出不是我所期望的

[[1, 0, 0, 0, 1, 1, 1], [0, 1, 0, 0, 1, 1, 0], [0, 0, 1, 0, 0, 1, 1], [0, 0, 0, 1, 1, 0, 1]]

是的，它是正确的，但图形输出不同。还有其他选择吗？

Answer 1

尝试这样的事情

System.out.println("[");
for (int i = 0; i < myArray.length; i++) {
    System.out.print("  [ ");
    for (int j = 0; j < myArray[i].length; j++) {
        System.out.print(myArray[i][j] + " ");
    }
    System.out.println("]");
}
System.out.println("]");
