楼主你的正则后面有个空格注意到没有啊。。给的字符串要匹配的话后面应该也有空格啊：
String a= "jerry,98|tom,99|jack,10|anne,100 ";
->
String   a= "jerry,98 |tom,99 |jack,10 |anne,100 ";

//code
public   class   ChaiFen   {
     public   static   void   main(String   args[]){
     String   a= "jerry,98 |tom,99 |jack,10 |anne,100 ";
     Pattern   p=Pattern.compile( "([a-zA-Z]+)\\W{1}([0-9]+)\\W{0,1} ");
     Matcher   ma=p.matcher(a);
     System.out.println(ma.matches());
     ma.reset();
     String[] arr=new String[4];
     int i=0;
     while(ma.find()){
         //System.out.println(ma.group(1));//不知道怎么把这个放到数组里面？？？
         arr[i]=new String();
         arr[i]=ma.group(1);
         i++;
     }
     ma.reset();
     String[] num=new String[4];
     int j=0;
     while(ma.find()){
         //System.out.println(ma.group(2)); 
         num[j]=new String();
         num[j]=ma.group(2);
         j++;
}
     System.out.print("The Strings:");
     for(String str:arr){
   	  System.out.print(str+"  ");
     }
     System.out.println();
     System.out.print("The Nums:");
     for(String str:num){
   	  System.out.print(str+"  ");
     }
}
}


打印结果是：
false
The Strings:jerry  tom  jack  anne 
The Nums:98  99  10  100
