Java to convert string to long10/7/2023 ![]() if there are any empty spaces also take it out. replace all commas if present with no comma Here, a String value is converted into double values taking the commas into consideration. If we want to convert a value that contains commas then use replaceAll() method to replace that commas and the use parseDouble() method to get double value. String s2 = "mohit" //NumberFormatException String s1 = "500.77" //String declarationÄouble i1 = Double.valueOf(s1) // Double.valueOf() method converts a String into Double ![]() Here, a String value is converted into a double value by using the valueOf() method. That gets rid of useless object creation. In order to fix this, use trim (): Long.valueOf (im ()) I would recommend you to use LongparseLong instead of LongvalueOf as it returns long instead of Long. This method is used to convert a String into a Double Object. However, Long.valueOf () only works strings that only consist of numbers. So at the end of the day, the table after executing a query. ![]() So in the example above, there would be three rows. The valueOf() method is a part of Double class. There are other columns that share the same data and as such, the 'cpeIndex' field here would be the start of a new row with its accomponying data and the other existing columns would just carry over the same data to the other rows. public class StudyTonightÄouble i = Double.parseDouble(s) // Double.parseDouble() converts the string into doubleĤ54.9 2. ![]() This method parses the string as a signed decimal long, and returns the resulting long value. Here, a String value is converted into double type value by using the parseDouble() method. To convert a string to a long in Java, you can use the parseLong () method of the class. It is a static method and is used to convert a String into a double. The parseDouble() method is a part of the Double class. Whenever a data(numerical) is received from a TextField or a TextArea it is in the form of a String and if we want double type then it is required to be converted into a double before performing any mathematical operation. Also, a String can be converted into a Double object using the Double.valueOf() method. Unnest(cast(json_extract(data, '$.In Java, a String can be converted into a double value by using the Double.parseDouble() method. Json_extract_scalar(m, '$.rpdUsrfPortnum') rpdUSrfportnum Json_extract_scalar(m, '$.apeMacAddress') apemacaddress, Json_extract_scalar(m, '$.macAddress') macaddress, Json_extract_scalar(m, '$.cpeStatus') cpeIndex, Conclusion is that youre running a different code than you think youre running - parsing the string as long should work without issues. The valueOf () method of String class is used to get a string from long. However, youre claiming that youre having the problem with this code: long timeMillisLong.parseLong (time) which clearly isnt true, as per stack trace. Select json_extract_scalar(m, '$.cpeIndex') cpeIndex, Long is a wrapper class in Java that is used to handle long type objects. If not all keys present in all objects you can also cast to 'json': - query Unnest(cast(json_extract(data, '$.List') as array(map(varchar, json)))) as t(m) Try(m) apemacaddress, - one JSON object is missing this prop You can process it using json functions, casting to array of map and unnest: - sample data
