java - 如何在水平表格中垂直打印

Question

所以我正在编写一个程序，我想做的事情之一就是打印一张转换后的 ASCII 字符表，如下所示

 DEC HEX OCT  DEC HEX OCT  DEC HEX OCT  DEC HEX OCT
A 65 101 25 C 66 111 232  E 12 32  12  G 21 56  12
B 12 89 23  D 45 124  23  F 34 123 10  H 89 203 8

我已经完成了程序的转换部分，我只需要一些帮助让表格以正确的方式打印

有人有什么建议吗？

我的代码

public static void getInputs(String[] args) {
    //c1, c2, and c3 are the characters the user enters
    //selector is what determends how the method will print

    char c1 = args[0].charAt(0);
    char c2 = args[1].charAt(0);
    char c3 = args[2].charAt(0);
    int letter1 = (int) c1;
    int letter2 = (int) c2;
    String selector = Character.toString(c3);
    char[] arr;
    int index = 0;
    arr = new char[c2 - c1 + 1];
    //Yif the selector is the letter h the program will print horizontaly     
    //Xif the selector is the letter v the program will print vertically 
    //Yprogram prints horizontaly
    //Xprogram prints vertically
    //Yselector works
    //Xclean up everything

    if (letter2 >= letter1){
    if (selector.equals("h")) {
            //(char)x is the letter
            //x is the number
            int counter = 0;
            for (int x = (int) c1; x <= c2 && counter < 4; ++x) {

                System.out.print("     " + "DEC " + "Oct " + "Hex");
                ++counter;
            }
            System.out.println("\n");
            for (int x = (int) c1; x <= c2; ++x) {
                if (counter % 4 == 0) {
                    System.out.println("");
                }

                String hex = Integer.toHexString(x);
                String oct = Integer.toOctalString(x);
                arr[index++] = (char) x;
                System.out.print("   " + (char) x + "  "
                        + x + " " + oct + "  " + hex);
                ++counter;
            }
            pause();
        } else if (selector.equals("v")) {


         int counter = 0;
            for (int x = (int) c1; x <= c2 && counter < 4; ++x) {

                System.out.print("     " + "DEC " + "Oct " + "Hex");
                ++counter;
            }
            System.out.println("\n");
            for (int x = (int) c1; x <= c2; ++x) {
                if (counter % 4 == 0) {
                    System.out.println("");
                }

                String hex = Integer.toHexString(x);
                String oct = Integer.toOctalString(x);
                arr[index++] = (char) x;
                System.out.print("   " + (char) x + "  "
                        + x + " " + oct + "  " + hex + "\n");
                ++counter;
            }
            pause();




        } else {
            System.out.println("Error: Third input parameter must be h or v.");
            System.out.println("Program now terminating.");
            //?insert pause and end the program here
        }
    }else{
    System.out.println("Error: First input parameter must precede "
    + "the second in the ASCII sequence.");
    }

}

我知道我的代码有点困惑，您可以将内容放入方法中，但现在我只专注于让表格正确打印。

我也为我的问题带来的坏名声道歉。

打印由制表符分隔的值。摘自您的代码片段

标题:

            System.out.print("     " + "\t\tDEC " + "\t\tOct " + "\t\tHex");
            ++counter;
        }

值(value)观:

            System.out.print("   " + (char) x + "\t\t"
                    + x + "\t\t" + oct + "\t\t" + hex);
            ++counter;
        }
