Compare 2 Java arraylists of different objects and add the matching rows to a new List

由 こ雲淡風輕ζ 提交于 2019-12-03 21:51:01
We need to compare 2 arraylists of different objects having some common fields, and then store the matching rows to a new arraylist. I have searched for solutions, but wasn't able to get what I need. List<Person> personList = new ArrayList<Person>(); Person: private String firstName; private String lastName; private String street1; private String street2; private String city; private String stateCode; private String zipCode; List<PersonNpi> npiList = new ArrayList<PersonNpi>(); PersonNpi: private String name; private String npi; private Address address; So I need to check if the name & address

Problem comparing dates (times) in Android

由 一世执手 提交于 2019-12-03 21:13:34
I am having a problem when i am trying to compare two dates in Android. I am not sure if it is a problem with the emulator or if i have a problem in the code itself. The thing is the code works in a normal Java program environment, which confuses me even more. I have the following code to compare dates in Android 2.1 : public boolean compareDates(String givenDateString) { SimpleDateFormat sdf = new SimpleDateFormat("HH:mm"); boolean True; try { True = false; Date givenDate = sdf.parse(givenDateString); Date currentDate = new Date(); if(givenDate.after(currentDate)){ True = true; } if(givenDate

I'm trying to understand Microsoft's DoubleUtil.AreClose() code that I reflected over

由 霸气de小男生 提交于 2019-12-03 20:42:56
问题 If you reflect over WindowsBase.dll > MS.Internal.DoubleUtil.AreClose(...) you'll get the following code: public static bool AreClose(double value1, double value2) { if (value1 == value2) { return true; } double num2 = ((Math.Abs(value1) + Math.Abs(value2)) + 10.0) * 2.2204460492503131E-16; double num = value1 - value2; return ((-num2 < num) && (num2 > num)); } I'm trying to understand two different things: Where did they come up with the formula for num2? I guess I just don't understand the

Case insensitive compare against bunch of strings

由 醉酒当歌 提交于 2019-12-03 20:37:10
What would be the best method to compare an NSString to a bunch of other strings case insensitive? If it is one of the strings then the method should return YES, otherwise NO. Here's a little helper function: BOOL isContainedIn(NSArray* bunchOfStrings, NSString* stringToCheck) { for (NSString* string in bunchOfStrings) { if ([string caseInsensitiveCompare:stringToCheck] == NSOrderedSame) return YES; } return NO; } Of course this could be greatly optimized for different use cases. If, for example, you make a lot of checks against a constant bunchOfStrings you could use an NSSet to hold lower

Compare Tables in BigQuery

由 瘦欲@ 提交于 2019-12-03 17:00:54
How would I compare two tables ( Table1 and Table2 ) and find all the new entries or changes in Table2 . Using SQL Server I can use Select * from Table1 Except Select * from Table2 Here a sample of what I want Table1 A | 1 B | 2 C | 3 Table2 A | 1 B | 2 C | 2 D | 4 So, if I comparing the two tables I want my results to show me the following C | 2 D | 4 I tried a few statements with no luck.
