解析字符串并将其迭代到arraylist[closed]

Question

我有一个值为：

字符串lstr=[12.88,77.56],[12.81,77.7156]

final ArrayList<Coordinate> points = new ArrayList<Coordinate>();
        points.add(new Coordinate(12.88, 77.56));
        points.add(new Coordinate(12.81, 77.7156));

Answer 1

您可以执行如下例所示的操作。注意：您可以改进正则表达式以检查空格等：

String lstr = "[12.88, 77.56],[12.81, 77.7156]";

List<Coordinate> cors = new ArrayList<Coordinate>();

String []coordinates = lstr.split("\\],\\[");

for(String cordinate:coordinates)
{
    String []xy = cordinate.split(",");
    cors.add(new Coordinate(xy[0],xy[1]));
}
System.out.println(cors);
