把隨機輸入的一句話比如:It's only a test!存放在一個char[]的數(shù)組中，統(tǒng)計char[]中的單詞個數(shù)和標(biāo)點符號的個數(shù)。

? package?com.faintbear;

import?java.io.*;
public?class?Test{
????public?static?void?main(String[]?args)?throws?Exception{
????????BufferedReader?br?=?new?BufferedReader(new?InputStreamReader(System.in));
????????String?str?=?br.readLine();
????????if(str?==?null)?throw?new?Exception("");
????????char[]?c?=?str.toCharArray();
????????int?words?=?0;
????????int?ip?=?0;
????????boolean?wordflag?=?false;
????????for(int?i=0;i<c.length;i++){
????????????if((c[i]>='a'?&&?c[i]?<=?'z')?||?(c[i]?>=?'A'?&&?c[i]?<=?'Z')){
????????????????if(wordflag)?{
????????????????????continue;
????????????????}else{
????????????????????words++;
????????????????}
????????????????wordflag?=?true;

????????System.out.println("words="?+?words);
????????System.out.println("ip="?+?ip);
????????for(int?i=0;i<c.length;i++)
????????{
??????????System.out.print("c["+i+"]="+c[i]);
????????}
