Java-String类的常用方法总结.pdf

Java中的String类是编程中最常用的类之一，它用于表示不可变的字符序列。在这个总结中，我们将深入探讨String类的一些核心特性和方法。首先，String类位于java.lang包中，这意味着它对所有Java程序都是自动导入...

@Override public void onRFDData(TagData[] tagData) { requireActivity().runOnUiThread(new Runnable() { @Override public void run() { if (tagData != null && tagData.length > 0) { for (TagData tag : tagData) { String rfidNO = tag.getTagID(); if (rfidNO.startsWith("40") && !tags.contains(rfidNO)) { tags.add(rfidNO); String hex = rfidNO.replaceAll("40", ""); if (!hex.isEmpty()) { try { String code = RSAEncryptProvider.hexToAscii(hex); if (code.length() > 10) { String sn = code.substring(code.length() - 7); // 7位序列号 String style = code.substring(code.length() - 10, code.length() - 7); // 3位款式 String spec = code.substring(0, code.length() - 10); // 型号 ExcelImportViewModel m = iv.inventoryList.stream().filter(t -> t.spec.equalsIgnoreCase(spec) && t.style.equalsIgnoreCase(style)).findFirst().orElse(null); if (m != null) { m.check_inventory += 1; if (m.check_inventory == m.real_inventory) { m.status = 1; // } else if (m.check_inventory > m.real_inventory) { m.status = 2; } } } } catch (Exception ex) { } } } } updateView(); } } }); }如何将 String sn = code.substring(code.length() - 7); // 7位序列号 String style = code.substring(code.length() - 10, code.length() - 7); // 3位款式 String spec = code.substring(0, code.length() - 10); 展示到一个新的页面

要将这三个字符串展示到一个新的页面中，可以通过...String style = bundle.getString("style"); String spec = bundle.getString("spec"); 5.将这三个字符串展示在新的页面中的TextView或者其他控件中即可。

filename = filename.replaceAll("\r\n", ""); } else { // IE及其他浏览器 filename = URLEncoder.encode(filename, "utf-8"); filename = filename.replace("+"," "); } //推送浏览器 response.set...

val formatter = SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.getDefault()) val dateTimeString1 = formatter.format(dateTimeString) val date = formatter.parse(dateTimeString1)

然后，我们使用 formatter.parse(dateTimeString) 将字符串解析成 Date 对象，再使用 formatter.format() 方法将 Date 对象格式化为指定的日期时间字符串。请注意，formatter.parse() 方法会抛出 Parse...

try { // 获取当前日期 LocalDate currentDate = LocalDate.now(); // 定义日期格式 DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd"); // 转换为指定格式的字符串 String dateString = currentDate.format(formatter); // 构建URL对象 URL url = new URL(API_BASE_URL + "?begin=" + dateString + "&Methodname=" + URLEncoder.encode(str, "UTF-8")); // 创建HttpURLConnection对象 HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // 设置请求方法为GET connection.setRequestMethod("GET"); // 设置Basic认证信息 String auth = API_USERNAME + ":" + API_PASSWORD; byte[] authBytes = auth.getBytes(StandardCharsets.UTF_8); String authHeaderValue = "Basic " + Base64.getEncoder().encodeToString(authBytes); connection.setRequestProperty("Authorization", authHeaderValue); // 设置字符编码为UTF-8 connection.setRequestProperty("Accept-Charset", "UTF-8"); // 发送请求 int responseCode = connection.getResponseCode(); // 读取响应数据 BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), StandardCharsets.UTF_8)); StringBuilder responseBuilder = new StringBuilder(); String line; while ((line = reader.readLine()) != null) { responseBuilder.append(line); } String response = responseBuilder.toString(); // 关闭连接 connection.disconnect(); // 返回响应数据 ObjectMapper objectMapper = new ObjectMapper(); JsonNode rootNode = objectMapper.readTree(response); String ls = rootNode.get("data").get(0).toString(); return ls; } catch (Exception e) { e.printStackTrace(); return "Error: " + e.getMessage(); }其中ls的值是"{\"ls\":\"603\"}"，修改一下，ls只需要”603“

在获取到 ls 的值时，可以使用 JsonNode 的 get() 方法获取到 ls 字段对应的值，然后使用 String 的 replaceAll() 方法去除多余的字符，具体修改如下： try { // 获取当前日期 LocalDate ...

public String execute(Message msg) throws Exception { logger.info("CreateInstanceWork - execute :begin ,workId=" + msg.workId + " ,param=" + msg.param); String istanceId = null; try { CreateInstanceParam param = JSON.parseObject(msg.param, CreateInstanceParam.class); //获取镜像在ral层的真实Id Image image = computeInvokeManager.getImage(param.imageId); if(null==image){ throw new ResourceIsDeletedErrorException(); } param.imageId=image.privateId; param.macName = StringUtils.replace(param.macName, "-", ":"); //param.macName = param.fixedMac1; Instance instance = ralInvokeManager.createInstance(param); instance.vmType = param.type; instance.imageId=image.id; instance.accountName = instance.name; instance.sceneType = param.sceneType; if(StringUtils.isNotEmpty(image.name)){ instance.imageName=image.name; }else{ instance.imageName = "未知镜像-" + instance.imageId; } if(instance.osType == null){ instance.osType = INSTANCE_CONFIG.OSTYPE_WINDOWS; } instanceDao.addInstance(instance); instanceDao.initInstance(instance.id); instanceDao.lockInstance(instance.id); workRegister.updateWorkResource(msg.workId, instance.id); istanceId = instance.id; logger.info("CreateInstanceWork - execute :end ,workId=" + msg.workId + " ,instanceId=" + istanceId); } catch (BaseInvokeException e) { logger.error("CreateInstanceWork - execute : createInstance failed !", e); String message = e.getMessage(); SrvError srvError = null; try { srvError = JSON.parseObject(message, SrvError.class); } catch (Exception e1) { } if (null != srvError) { workResponser.responeWorkDetailEnd(msg.workId, srvError.code + ""); } else { workResponser.responeWorkDetailEnd(msg.workId, e.getCode() + ""); } throw e; } catch (Exception e) { logger.error("CreateInstanceWork - execute : createInstance failed !", e); throw e; } finally { } return super.execute(msg, istanceId); }这段代码是什么意思

这段代码是一个Java方法的实现，它接收一个Message对象作为参数，并返回一个String类型的结果。代码首先通过日志记录器logger输出一条日志，然后定义了一个变量istanceId并初始化为null。接下来，代码...

int posX = e.X - ((PictureBox)sender).Left - this.Left; int posY = e.Y - ((PictureBox)sender).Top - this.Top - (this.Height - this.ClientRectangle.Height); int row = 0; string itemName = (string)e.Data.GetData(DataFormats.Text); if (posY > list.Count * 24) { list.Add(new List<string>()); row = list.Count - 1; }中row = Convert.ToInt32((posY - 1) / 24);是什么意思

这段代码主要是在处理拖放事件，其中通过计算鼠标在控件内的位置，计算出拖动到哪一行，并将该行的...其中row = Convert.ToInt32((posY - 1) / 24)的作用是将鼠标在控件内的位置转换为对应的行数，其中24为每行的高度。

优化这段代码@PostMapping("/login") @ResponseBody @PassToken public Object login(String username,String password) throws IOException { String url="http://42.177.95.222:9202/platform/yugang/task/getToken"; HttpClient client = HttpClients.createDefault(); //默认post请求 HttpPost post = new HttpPost(url); //拼接多参数 JSONObject json = new JSONObject(); json.put("username", "渔业协会"); json.put("password", "Yuye!@#qwe"); post.addHeader("Content-type", "application/json; charset=utf-8"); post.setHeader("Accept", "application/json"); post.setEntity(new StringEntity(json.toString(), Charset.forName("utf-8"))); HttpResponse httpResponse = client.execute(post); HttpEntity entity = httpResponse.getEntity(); String s = EntityUtils.toString(entity); JSONObject jo = JSONObject.parseObject(s); String token = jo.getJSONObject("data").getString("token"); System.out.println("dsadasdasdsadasd"+token); return verify(token); } public Object verify(String token) throws IOException { String url="http://42.177.95.222:9202/platform/yugang/task/verify"; HttpClient client = HttpClients.createDefault(); //默认post请求 HttpPost post = new HttpPost(url); //拼接多参数 JSONObject json = new JSONObject(); json.put("token",token); post.addHeader("Content-type", "application/json; charset=utf-8"); post.setHeader("Accept", "application/json"); post.setEntity(new StringEntity(json.toString(), Charset.forName("utf-8"))); HttpResponse httpResponse = client.execute(post); HttpEntity entity = httpResponse.getEntity(); String s = EntityUtils.toString(entity); JSONObject jo = JSONObject.parseObject(s); return jo; }

1. 将重复的代码抽取成公共方法，避免代码冗余。 2. 使用连接池管理 HttpClient 的连接，提高连接的复用率和性能。 3. 使用 try-with-resources 语句关闭 HttpClient 和 HttpEntity 对象，避免资源泄漏。下面是...
