Post increment in Java -

this question has answer here: post increment operator not incrementing in loop 4 answers in code segment, [1]int i=0; [2]i = i++; [3]system.out.println(i); in line 2, executed expression first (which assigned 0 i) , should increment value 1. in system.out.println(i) , getting answer 0 instead of 1.can explain reason this? i++ not yield variable, value. i++ yields 0. then incremented 1. then 0 assigned i. summary: precedence of operators maybe not expected. or @ least might've misunderstood actual increment of happening. it's normal show people use of i++ can split 2 lines line after doing incrementation - that's not correct. happens before assignment operator.

according apple (9.3 , 9.9 https://developer.apple.com/appstore/resources/approval/guidelines.html ) need tell ( doesn´t explicitly understanding ) user of app not on wifi network , if streams content of app cost him lots of money. what can't find out is : have give user constant warnings e.g for every link clicks or enough give him warning one time while in app ? mean in app hours (hopefully :-)). edit: after rereading https://developer.apple.com/appstore/resources/approval/guidelines.html see have not totally understood guideline. it says : 9.3 audio streaming content on cellular network may not use more 5mb on 5 minutes 9.9 video streaming content on cellular network longer 10 minutes must use http live streaming , include baseline 64 kbps audio-only http live stream so understanding need tell user usage after 10 minutes or after 5mb download after 5 minutest ? no can´t be! can it? my program container around youtube streaming video them.

spring - Storing trailing zeroes in database with JPA and Oracle -

i need store prices in database. i'm using jpa, i've got model this: @entity @table(name="products") public class product { @id @generatedvalue(strategy=generationtype.identity) private long id; @column(name="price") private float price; } the problem when fill price form inputs values "4.20", on oracle database "4.2", losing trailing zero. how can solve problem? edit: since i'm using jpa, have avoid writing queries in native oracle dialect. store products (with prices) write em.persist(product) , em entitymanager you can't solve it, , i'd suggest it's not problem. that's how oracle stores number values: least precision needed. if entered price 4.00 stored 4 . note java won't default 2 decimals either when displaying value. need specify number of decimal places. and, if possible, i'd use bigdecimal instead of float price. float type isn't precise. alte
