WordCounter的设计与实现

本代码段实现了统计字母，空格，数字，其他字符，以及单词数等操作。目前仅能够通过键盘输入，预留了从文件导入的接口，后续会实现。

代码写的很LOW，有些BUG到现在还没有解决。

来几张图：

附上代码：

package wordCounter;import java.util.Scanner;public class WordCounter {    static int welcome() {        Scanner scanner = new Scanner(System.in);        System.out.println("HI!You can input a string and you can import from your file!And we will give you some message that you want konw!");        System.out.println("1、input a string \n2、implort from file");        int choice=scanner.nextInt();        return choice;      }    private static String getUserString(int choice) {        String s = null ;        if (choice==1) {            //input string            System.out.println("Please input your string!");            Scanner scanner=new Scanner(System.in);            s = scanner.nextLine();        }else if (choice==2) {            //get string from file        }else {            welcome();        }        return s;    }    /**     * get number\character\black\other     * @param s     */    private static void getMessageOne (String s) {        char[] myChar = s.toCharArray();        for (int i = 0; i < myChar.length; i++) {            char temp = myChar[i];            if (temp >= '0' && temp <= '9') {                num[0]++;            } else if (temp >= 'a' && temp <= 'z' || temp >= 'A' && temp <= 'Z') {                num[1]++;            } else if (temp == ' ') {                num[2]++;            } else {                num[3]++;            }        }    }    private static void showMessage() {        System.out.println("**************************");        System.out.println("Your counter at here:");        System.out.println("number:"+num[0]);        System.out.println("character:"+num[1]);        System.out.println("blank:"+num[2]);        System.out.println("other:"+num[3]);        System.out.println("words:"+num[4]);        System.out.println("**************************");        System.out.println("Thank you for your using!");    }    static int num[] = { 0, 0, 0, 0 ,0};// 数字、字母、空格、其他、单词    public static void main(String[] args) throws InterruptedException {        String s=getUserString(welcome());        System.out.println("Now,we doing some work!Please wait!");        //System sleep!        //Thread.currentThread().sleep(5000);        getMessageOne(s);        getMessageTwo(s);        showMessage();    }    private static void getMessageTwo(String s) {        // TODO Auto-generated method stub        System.out.println("There are the word!");         String s1[] = s.split(" ");//         for(int i=0;i<s1.length;i++) {             // System.out.println(s1[i]);              num[4]++;//计数变量         }     }}
