如题，已完成了部分，不知道如何找出单词和汉字的个数？public class t6{public static void main(String[] args){String str="司”，，面试，t5.java";
int letters=0;
int numbers=0;
int chinese=0;
int ch_punctuation=0;
int words=0;
int punctuation=0;char c;
for(int i=0;i<str.length();i++){
c=str.charAt(i);
if(Character.isLetter(c)){
letters++;}else if(Character.isDigit(c)){
numbers++;}else if((int)c>127){
ch_punctuation++;}else if(Character.isWhitespace(c)){
                  
continue;}else{punctuation++;
}}
System.out.println("letter:"+letters+";  numbers:"+numbers+";  全角标点:"+ch_punctuation+";  chinese:"+chinese+" words:"+words+"; 英文标点:"+punctuation+";  length:"+str.length());}
}

Answer 1

String str="司”，，面试，t5.java";
        int i=0,j=0,k=0;
        Pattern p = Pattern.compile("[\u4E00-\u9FA5]+");
        Matcher m = p.matcher(str);
        while(m.find())
            i++;
        p = Pattern.compile("\\w+");
        m = p.matcher(str);
        while(m.find())
            j++;
        p = Pattern.compile("[,\\.;:'\"，。、？；：’”]");
        m = p.matcher(str);
        while(m.find())
            k++;
        
        System.out.println(i+"\t"+j+"\t"+k);

Answer 2

Pattern p = Pattern.compile("[\u4E00-\u9FA5]");

Answer 3

\w 
匹配包括下划线的任何单词字符。等价于'[A-Za-z0-9_]'。
