java - 以表格形式显示

Question

嗨，这是我计算术语频率的代码。

System.out.println("Please enter the required word  :");
    Scanner scan = new Scanner(System.in);
    String word = scan.nextLine();
    String[] array = word.split(" ");
    int filename = 11;
    String[] fileName = new String[filename];
    int a = 0;

    for (a = 0; a < filename; a++) {
        try {
            File file = new File(
                    "C:\\Users\\user\\fypworkspace\\TextRenderer\\abc" + a
                            + ".txt");
            System.out.println("File = abc" + a + ".txt");
            for (int i = 0; i < array.length; i++) {

                System.out.println(array[i]);

                int totalCount = 0;
                int wordCount = 0;
                int numDoc2 = 0;

                Scanner s = new Scanner(file);
                {
                    while (s.hasNext()) {
                        totalCount++;
                        if (s.next().equals(array[i]))
                            wordCount++;

                    }

                    System.out.println("Word count:  " + wordCount);
                    System.out.println("Total count: " + totalCount);
                    System.out.printf("Term Frequency:   %8.4f",
                            (double) wordCount / totalCount);

                    System.out.println("\n");

                }
            }
        } catch (FileNotFoundException e) {
            System.out.println("File is not found");

        }

    }

不要使用System.out.println(String)，而是使用System.out.print(String)。

System.out.print(String) 将打印出数据，而不会导致以下 System.out.print(String) 在下一行开始。这将帮助您以正确的格式获得数据输出

将顶部文件名的打印语句更改为

System.out.print("abc" + a + ".txt");

并将末尾的打印语句更改为

System.out.print(" " + wordCount);
System.out.print(" " + totalCount);
System.out.printf(" %8.4f", (double) wordCount / totalCount);
System.out.println();
