用Java写一个打印16进制编码ASCII字符集，要求八行十六列

可以使用以下Java代码实现：

public class HexAsciiTable {
    public static void main(String[] args) {
        int rows = 8;
        int cols = 16;
        int start = 0;
        int end = 255;
        int count = 0;
        
        for (int i = start; i <= end; i++) {
            System.out.print(String.format("%02X ", i));
            count++;
            if (count == cols) {
                System.out.println();
                count = 0;
                rows--;
                if (rows == 0) {
                    break;
                }
            }
        }
    }
}

这段代码使用循环打印出ASCII字符集的16进制编码表，每行打印16个字符，一共打印8行。通过设置start和end变量来指定要打印的字符集范围。

用Java写一个打印十六进制编码ASCII字符集，

以下是使用Java打印十六进制编码ASCII字符集的代码：

public class AsciiHexPrint {
    public static void main(String[] args) {
        for (int i = 0; i < 128; i++) {
            System.out.printf("%3d: 0x%02X %c\n", i, i, (char) i);
        }
    }
}

输出结果如下：

  0: 0x00
  1: 0x01

以上代码使用了循环来遍历ASCII字符集中的所有字符，通过使用`printf`方法打印出每个字符的十进制值、十六进制值和字符本身。注意，要将整数值强制转换为字符，以便打印出字符本身。

打印16进制的Ascii字符集，用java，；八行16列

好的，以下是Java代码实现：

public class PrintAsciiHex {
    public static void main(String[] args) {
        int count = 0;
        for (int i = 0; i < 128; i++) {
            // 转换为16进制字符串
            String hex = Integer.toHexString(i);
            // 保证输出两位
            if (hex.length() == 1) {
                hex = "0" + hex;
            }
            System.out.print(hex.toUpperCase() + " ");
            count++;
            if (count == 16) {
                count = 0;
                System.out.println();
            }
        }
    }
}

输出结果为：

00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 
10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F
