Kirat[ad_1] Assuming you want a Map<User.userId, List<UserData.customerId>> you can use this: Map<Long, List<Long>> result = users.stream() .collect(Collectors.toMap( User::getUserId, u -> u.getUserData().stream() .map(UserData::getCustomerId) .collect(Collectors.toList()) )); 3 [ad_2] solved Java 8 – collecting into a map from a list of objects with nested list
[ad_1] select xxpst_util_pkg.get_type_id_by_code (‘CHANGE_REQUEST’, ‘MILESTONE_DUE_DATE_CHANGE’) comment_type_id from dual is a mean of calling a PLSQL function from a SQL statement. DUAL returns a single row, so it just yields the output of the function. It’s not dissimilar from doing my_variable := xxpst_util_pkg.get_type_id_by_code (‘CHANGE_REQUEST’, ‘MILESTONE_DUE_DATE_CHANGE’) In terms of what comes back, you’d need to look in … Read more
[ad_1] It’s x > (y / z). The expression y / z returns a number which is being compared to x. The operator precedence table explains why it works even without round brackets. ┌────────────────┬───────────────────────────────┐ │ Operators │ Precedence ↓ │ ├────────────────┼───────────────────────────────┤ │ multiplicative │ * / % │ │ relational │ < > <= >= … Read more
[ad_1] First one you are only declaring and in second you declaring and initializing. If you use any instance of a class without initializing, then you will get null reference exception as Object reference not set to an instance of an object [ad_2] solved Declaring C# variable with and without Constructor
[ad_1] raw_input returns a string. Strings are never equal to numbers. >>> ‘0’ == 0 False Compare the string with a string. For example, to check whether the string starts with specific character (sub-string), using str.startswith: if number.startswith(‘0’): … [ad_2] solved Determining the First Digit
[ad_1] You are currently loading two grammers into your recognizer. I believe digits.gram contains numbers. File menuGrammar = new File(modelsDir, “grammar/menu.gram”); recognizer.addGrammarSearch(MENU_SEARCH, menuGrammar); File digitsGrammar = new File(modelsDir, “grammar/digits.gram”); So I think what you could do is make a file letter.gram and load it into your program #JSGF V1.0; grammar speech; public <speech> = A … Read more
[ad_1] With the full code in the question we can now see it’s an integer overflow. 10000 * 180 * 3600 = 6,480,000,000. This is greater than 2,147,483,648 which is the max value of a 32-bit signed int. The results of the multiplication overflows to -2,109,934,592 and is then converted to double. To get the … Read more
[ad_1] You have a red exclamaition mark on your project. Eclipse is likly to not build your project if build path problems (e.g.) aren’t resolved. So go to the Problems tab and try to resolve your errors there. If that is finished Eclipse will build your project and gives more helpful errors Edit and that … Read more
[ad_1] You should move MouseHookProc definition outside of main. C++ does not allow function definitions inside of other functions. Among other things, (LPTHREAD_START_ROUTINE)clicker is also wrong, there is no need to perform cast here, instead clicker function must have correct signature, void down(); is actually a function declaration, not invocation. 2 [ad_2] solved expected a … Read more
[ad_1] Your problem is in this expression: len(cards – 1) cards appears to be a list; you can’t subtract 1 from a list. I suspect that you mean len(cards) – 1 [ad_2] solved How can i fix this Type Error that appears? [closed]
[ad_1] Try getting the half, then reverse: >>> l=[1,2,3,4,5,6] >>> l[len(l)//2:]=l[len(l)//2:][::-1] >>> l [1, 2, 3, 6, 5, 4] >>> slicing + slicing + reversing. 1 [ad_2] solved How to divide the list and sort in ascending and descending order using python?
[ad_1] SELECT MONTHNAME(curdate()); Doc or if you only need the first 3 letters SELECT substr(MONTHNAME(curdate()), 1, 3); 0 [ad_2] solved I want get month() function return value as ‘jan’,feb etc
[ad_1] It depends on your specific requirements. This prints the first two digits of an integer number let intVal = 12345 print(String(intVal).prefix(2)) Output: 12 Another way which only prints certain ones in the number: let intVal = 12345 let acceptableValues = [“1”, “2”] let result = String(intVal).filter { acceptableValues.contains(String($0)) } print(result) Output: 12 [ad_2] solved … Read more
[ad_1] I try to use syntactic sugar The conditional operator is not syntactic sugar. It’s a specific operator with a specific purpose, and you’re simply using it incorrectly. It is used for conditionally producing a value as an overall expression, one value if the condition is true and another if it’s false. For example: let … Read more
[ad_1] The || operator is similar to the keyword or but is different from the keyword or in extremely important ways. Below are two great write-ups on the topic, comparing the two and showing you how to use either one: http://devblog.avdi.org/2010/08/02/using-and-and-or-in-ruby/ New version, with video: http://devblog.avdi.org/2014/08/26/how-to-use-rubys-english-andor-operators-without-going-nuts/ The most important thing to note in what Avdi … Read more
