我需要从Java字符串令牌生成器获取子字符串.

我的插入字符串是= Pizza-1 * Nutella-20 * Chicken-65 *

        StringTokenizer productsTokenizer = new StringTokenizer("Pizza-1*Nutella-20*Chicken-65*", "*");
        do
        {
            try
            {
                int pos = productsTokenizer .nextToken().indexOf("-");
                String product = productsTokenizer .nextToken().substring(0, pos+1);
                String count= productsTokenizer .nextToken().substring(pos, pos+1);
                System.out.println(product + "   " + count);
            }
            catch(Exception e)
            {

            }
        }
        while(productsTokenizer .hasMoreTokens());

我的输出必须是：

Pizza  1
Nutella  20
Chicken  65

我需要将产品值和计数值放在单独的变量中,以便将该值插入数据库中.

我希望你能帮助我.

解决方法:

您可以使用String.split()作为

String[] products = "Pizza-1*Nutella-20*Chicken-65*".split("\\*");

for (String product : products) {
    String[] prodNameCount = product.split("\\-");
    System.out.println(prodNameCount[0] + " " + prodNameCount[1]);
}

输出量

Pizza  1
Nutella  20
Chicken  65
