我正在尝试用Java编写一个程序,它将获取一个IP地址并转换为二进制文件.

这是我到目前为止:

import java.util.Scanner;

public class IpConverter{

public static void main (String[]args)
{

    int result;

    String data_in;

    int data_out;

        Scanner scan = new Scanner(System.in);

        try
        {
            System.out.print("Enter an IP address: ");
            data_in = scan.next();

            data_out = Integer.parseInt(data_in, 10);
            System.out.println (data_in + "is equivalent to" + data_out);
        }
        catch (NumberFormatException nfe){
            System.out.println("Wrong data type!");

        }
    }
}

有没有办法创建某种类型的For循环来用空格分隔字符串？到目前为止,我可以显示一个字符串并查找它有多少个字符.

import java.util.Scanner;
import java.lang.String;

public class Word{
  public static void main(String args[])
  {
     Scanner scan = new Scanner(System.in);

     int b;

    String word;

    System.out.println ("Enter a word: ");
    word = scan.next();

    b = word.length();

    System.out.println (word);
    System.out.println (b);
  }
}
