Get dimension from XML and set text size in runtime
...ur phone screen density is obviously hdpi (240dpi) so it uses 1.5 scale to convert dp to sp. Simple math 18 * 1.5 = 27.
It seems that your tablet density is mdpi (160dpi) so scale is just 1:1.
But if you compare real size of both texts it should be the same.
The best way is just create two dimens...
Spring Boot + JPA : Column name annotation ignored
...implicitly generated from the field name.
The ImprovedNamingStrategy will convert CamelCase to SNAKE_CASE where as the EJB3NamingStrategy just uses the table name unchanged.
If you don't want to change the naming strategy you could always just specify your column name in lowercase:

Java Multiple Inheritance
...classes, although those are not so natural to use in Java (you have to use converter methods and so on), this intro might be useful to get the idea: typeclassopedia.bitbucket.org

MySQL - length() vs char_length()
... in two bytes. Or UTF-8, where the number of bytes varies. For example:
select length(_utf8 '€'), char_length(_utf8 '€')
--> 3, 1
As you can see the Euro sign occupies 3 bytes (it's encoded as 0xE282AC in UTF-8) even though it's only one character.

What is pseudopolynomial time? How does it differ from polynomial time?
...mon intuition for polynomial time is "time O(nk) for some k." For example, selection sort runs in time O(n2), which is polynomial time, while brute-force solving TSP takes time O(n · n!), which isn't polynomial time.
These runtimes all refer to some variable n that tracks the size of the input. Fo...
