System.out.println("子网地址:"+subnet); System.out.println("- 起始地址: " + startAddress); System.out.println("- 结束地址: " + endAddress); System.out.println("- 广播地址: " + broadcastAddress); System.out.println( "- 新子网掩码: " + longToIp((0xFFFFFFFF << (32 - subnetMaskLengthRequired)) & 0xFFFFFFFF)); System.out.println("- 借位数: " + (subnetMaskLengthRequired - subnetMaskLength)); System.out.println("- 子网大小: " +subnetSize ); // 判断子网是A类、B类、还是C类地址 // 判断子网是A类、B类、还是C类地址 // 判断子网是A类、B类、还是C类地址 if (startLong >>> 24 == 0) { System.out.println("- Subnet Class: A"); } else if (startLong >>> 16 == 172 && (startLong >>> 20 & 0xF) >= 1 && (startLong >>> 20 & 0xF) <= 14) { System.out.println("- Subnet Class: B"); } else if ((startLong >>> 24 & 0xFF) >192&& (startLong >>> 24 & 0xFF) <= 223) { System.out.println("- Subnet Class: C"); } else { System.out.println("- Unknown subnet class"); }帮我把结果改成表格形式输出的Java代码

下面是将结果改为表格形式输出的Java代码：

System.out.println("+---------------+------------------------+------------------------+------------------------+------------------------+------------------+----------------------+");
System.out.println("|   Subnet Mask  |      Subnet Address     |      Start Address      |       End Address       |     Broadcast Address   | Subnet Class     |       Subnet Size     |");
System.out.println("+---------------+------------------------+------------------------+------------------------+------------------------+------------------+----------------------+");
System.out.printf("|   %d         | %15s | %15s | %15s | %15s | %16s | %20s |\n", subnetMaskLengthRequired, subnet, startAddress, endAddress, broadcastAddress, subnetClass, subnetSize);
System.out.println("+---------------+------------------------+------------------------+------------------------+------------------------+------------------+----------------------+");

请注意，此代码假定您已经定义并初始化了变量subnetMaskLengthRequired、subnet、startAddress、endAddress、broadcastAddress、subnetClass和subnetSize。
