string-java String字符串截取

java String字符串截取

比如這樣一個字符串
String a = "你好，今天是@2015@年@7@月@15@日";
String b = "時間為@16@@:@@05@";
怎麼樣截取2個一對的@中間的字符串 a = 2015,7,15 b = 16,:,05

最佳回答：

 public static String getResult(String str,String splitStr){
        String[] arr = ("1"+str+"1").split(splitStr);
        StringBuilder sd = new StringBuilder();
        for(int i=1;i<arr.length-1;i++){
            sd.append(arr[i]);
        }
        return sd.toString();
    }
    public static void main(String[] args) {
        String a = "你好，今天是@2015@年@7@月@15@日";
        String b = "時間為@16@@:@@05@";
        a = getResult(a,"@");
        b = getResult(b,"@");
        System.out.println("a="+a);
        System.out.println("b="+b);
    }
