怎么样解析字符串

public class test {
    private static String keywordname="aa*cc+bb";
    private static String keywordtype = "1|2|3";

    public test() {
    }

    public static void main(String[] args){
        String types[] = keywordtype.split("[|]");
        String names[] = new String[types.length];
        String operator[] = new String[types.length-1];
        int len = keywordname.length();
        int k=0;
        int ibegin = 0;
        for (int i=0; i<len-1; i++){
            if (keywordname.charAt(i) == '*'){
                names[k] = keywordname.substring(ibegin, i);
                operator[k] = " and ";
                k++;
                ibegin = i+1;
            }
            else if (keywordname.charAt(i) == '+'){
                names[k] = keywordname.substring(ibegin, i);
                operator[k] = " or ";
                k++;
                ibegin = i+1;
            }
        }
        names[k] = keywordname.substring(ibegin, len);
        for (int i=0; i<types.length; i++){
            System.out.println(types[i] + ": " + names[i] );
        }

}
}
