Java'；s替换方法不起作用

我试图在几分钟内替换routeName和RouteDuration，但rpelace方法不起作用。当我在run函数外部使用它时，它正在工作，但在内部它不工作。有什么想法吗？我已经添加了我试图运行的所有代码。我很抱歉，这是如此来回。我试着缩短它，让别人更容易阅读

看起来线程可能没有按照注释中的建议执行

这对我很有用：

package example;

public class Example {

     final String g="routeName:I-190 N; Electric Ave,routeDurationInMinutes";
     final Runnable rundatapoll = new Runnable() {
            @Override
            public void run() {
                  String route1=g;
                  System.out.println("BEFORE THREAD");
                  System.out.println(route1);
                  route1= route1.replace(",routeDurationInMinutes","");
                  route1= route1.replace("routeName:","");
                  System.out.println("AFTER RUNNING THREAD:");
                  System.out.println(route1);
                  System.out.println("DONE");
            }
    };

    public static void main(String[] args) {
        Example example = new Example();
        Thread thread = new Thread(example.rundatapoll);
        thread.start();
    }

}

输出：

BEFORE THREAD
routeName:I-190 N; Electric Ave,routeDurationInMinutes
AFTER RUNNING THREAD:
I-190 N; Electric Ave
DONE

ROUTES: 
Route name: I-190 N; Electric Ave
Route name: I-190 N; Greenville Rd

或者您可以使用JSON解析器。类似于：

package example;

import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonExample {

    public static void main(String[] args) {
        try {
            String json = "{\"routes\":[{\"routeName\":\"I-190 N; Electric Ave\",\"routeDurationInMinutes\":70,\"routeLengthKM\":83.865,\"routeLengthMiles\":52.111278915,\"toll\":false},{\"routeName\":\"I-190 N; Greenville Rd\",\"routeDurationInMinutes\":82,\"routeLengthKM\":92.569,\"routeLengthMiles\":57.519692099000004,\"toll\":false}],\"startPoint\":\"street address\",\"endPoint\":\"destination\",\"startLatitude\":\"42.20115054203528\",\"startLongitude\":\"-71.85038140607858\",\"endLatitude\":\"42.201220801535\",\"endLongitude\":\"-71.849075146695\"}";
            JSONParser parser = new JSONParser();
            JSONObject obj = (JSONObject) parser.parse(json);
            JSONArray routes = (JSONArray) obj.get("routes");
            System.out.println("ROUTES: ");
            for(Object route : routes) {
                JSONObject routeObj = (JSONObject) route;
                String routeName = routeObj.get("routeName") + "";
                System.out.println("Route name: " + routeName);
            }
        } catch (Exception exp) {
            throw new RuntimeException(exp);
        }
    }

}

输出：

BEFORE THREAD
routeName:I-190 N; Electric Ave,routeDurationInMinutes
AFTER RUNNING THREAD:
I-190 N; Electric Ave
DONE

ROUTES: 
Route name: I-190 N; Electric Ave
Route name: I-190 N; Greenville Rd

@tylerik你是否执行过

Runnable

？@tylerik这是你真正的代码吗？因为下面你提到你为了这个问题修改了它。让我们看看正在运行的真实代码。你能定义“不起作用”（

replace

方法对我来说似乎工作得很好）“我只是想让每个人都容易阅读“这是正确的方向。如果完整的代码包含与您的问题无关的部分，请不要发布。花点时间发布最小但完整（可编译）的代码示例（即使从零开始也是值得的，我经常发现自己在尝试创建时找到问题的解决方案）你添加了更多的代码，但它仍然不允许我们重现你的问题（看看John的答案，看看一个最小但完整的程序是什么样子）。请重新阅读Pshemo的评论。他是100%正确的。如果你尝试按照他说的去做，你很有可能自己很快就能解决问题。
