java中的正则表达式问题:为什么匹配不到
if   (strWord.matches( "[\ ",] ") 
 { 
             return   true; 
 }   
 当其中strWord= " "mm,aa "的时候,为什么return   false? 
 (strWord中有引号,逗号和字母)
------解决方案--------------------用String的matches匹配不到吧,可以用Matcher的find()方法 
 import java.util.regex.*; 
 public class Test 
 {     
 	 public static void main(String [] args) 
 	 { 
 	    Pattern p = Pattern.compile( "[\ ",] "); 
 	    Matcher m = p.matcher( "mm\ ",,nn "); 
 	    while(m.find()) 
 	    { 
 	    	System.out.println( "adf "); 
 	    }  	    	 
 	 } 
 } 
------解决方案--------------------import java.util.regex.* ;   
 public class RegexTest {  	 
 	public static void main(String[] args) {  		 
 		String word= "mm,aa ";  		 
 		System.out.println(strword(word)); 
 	}  	  		 
 	public static boolean strword(String word){ 
 		Pattern p = Pattern.compile( "\\w*([\ "]{1}|[,]{1})\\w* "); 
 		if(word!=null){ 
 			Matcher m = p.matcher(word);  			 
 			return m.matches(); 
 		}else{ 
 			return  true; 
 		}  		 
 	}
