有一个字符串，如"11.2美元34人民币"；如何将数字与单位分开，放入数组中呢，数组比如 attr[0]=11.2 attr[1]=美元 ,依次类推

import java.util.regex.Matcher;import java.util.regex.Pattern;public class Test3 {public static void main(String[] args) {String s = "11.2美元34人民币";String attr[] = new String[10];Pattern p = Pattern.compile("[\\u4e00-\\u9fa5]+|\\d+\\.\\d+|\\d+");Matcher m = p.matcher( s );int index = 0;while ( m.find() ) {attr[index++] = m.group();}for(int j=0;j<index;j++){System.out.println("attr["+ j + "] = " + attr[j]);}}}
