不正确的数据类型转换:
javaCopy code
try { String stringValue = "123"; int intValue = Integer.parseInt(stringValue); // Process the converted integer value } catch (NumberFormatException e) { e.printStackTrace(); // Handle incorrect data type conversion issue }
缺少必需的数据:
javaCopy code
try { JSONObject json = new JSONObject("{\"name\":\"John\"}"); String name = json.getString("name"); String age = json.getString("age"); // Missing "age" field // Process the parsed values } catch (JSONException e) { e.printStackTrace(); // Handle missing field or other JSON parsing issues }
非法输入数据:
javaCopy code
try { String input = "abc123"; int parsedValue = Integer.parseInt(input); // Process the parsed value } catch (NumberFormatException e) { e.printStackTrace(); // Handle illegal input data issue }
数据精度损失:
javaCopy code
try { double doubleValue = 123.456; int intValue = (int) doubleValue; // Loss of precision // Process the converted integer value } catch (ArithmeticException e) { e.printStackTrace(); // Handle precision loss issue }
解析器配置错误:
javaCopy code
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); dateFormat.setLenient(false); // Reject invalid dates try { Date parsedDate = dateFormat.parse("2023-01-32"); // Invalid date // Process the parsed date } catch (ParseException e) { e.printStackTrace(); // Handle parsing issue due to invalid date }
确保在处理 ParseException
时,适当地检查异常的类型,并采取适当的处理措施。详细的错误日志和异常堆栈信息对于定位和解决问题非常有帮助。
