java - 有没有办法在存储字符串时扫描文件并忽略 int 变量？

Question

我正在尝试扫描文本文件并将字符串存储到数组中，同时忽略第一行。当我运行代码时，它有一个空白点，并且数组缺少一个字符串。无论如何要扫描文件并让它跳过 int 值并包含所有字符串？

文件 file = new File("input.txt");

    Scanner scan = new Scanner(file);



    int size = scan.nextInt();

    String[] blocks = new String[size];

    for (int i = 0; i < blocks.length; i++) {

        blocks[i] = scan.nextLine();

    }

    System.out.println(Arrays.toString(blocks));

Try reading the entire line each time, including for the initial integer value:

File file = new File("input.txt");
Scanner scan = new Scanner(file);

int size = Integer.parseInt(scan.nextLine());
String[] blocks = new String[size];

for (int i = 0; i < blocks.length; i++) {
    blocks[i] = scan.nextLine();
}

System.out.println(Arrays.toString(blocks));
