Detect current device with UIUserInterfaceIdiom in Swift
To detect current device with iOS/Swift we can use UserInterfaceIdiom. It is an enum in swift, which tells which device is being used.The interface idiom provides multiple values in it’s enum which are.case unspecified @available(iOS 3.2, *) case phone // iPhone and iPod touch style UI @available(iOS 3.2, *) case pad // iPad style UI @available(iOS 9.0, *) case tv // Apple TV style UI @available(iOS 9.0, *) case carPlay // CarPlay style UIIn swift interfaceIdiom can be used in the following way:print(UIDevice.current.userInterfaceIdiom) if UIDevice.current.userInterfaceIdiom == .phone { print("running on iPhone") }When we run the above code ...
Read MoreUse boolean value to stop a thread in Java
A thread can be created by implementing the Runnable interface and overriding the run() method. Then a Thread object can be created and the start() method called.A thread can be stopped using a boolean value in Java. The thread runs while the boolean value stop is false and it stops running when the boolean value stop becomes true.A program that demonstrates this is given as follows:Exampleclass ThreadDemo extends Thread { public boolean stop = false; int i = 1; public void run() { while (!stop) { try { ...
Read MoreDisplay all tables inside a MySQL database using Java?
We will see here how to display all tables inside a MySQL database using Java. You can use show command from MySQL to get all tables inside a MySQL database.Let’s say our database is ‘test’. The Java code is as follows to show all table names inside a database ‘test’.The Java code is as follows. Here, connection is established between MySQL and Java −import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import com.mysql.jdbc.Connection; import com.mysql.jdbc.DatabaseMetaData; public class GetAllTables { public static void main(String[] args) throws SQLException { Connection conn = null; try { ...

Read MorePython program to count unset bits in a range.
Given a positive a number and the range of the bits. Our task is to count unset bits in a range. Input : n = 50, starting address = 2, ending address = 5 Output : 2 There are '2' unset bits in the range 2 to 5. Algorithm Step 1 : convert n into its binary using bin(). Step 2 : remove first two characters. Step 3 : reverse string. Step 4 : count all unset bit '0' starting from index l-1 to r, where r is exclusive. Example Code # ...
Read MorePython Unicode Database
The unicodedata module is used to access all of the Unicode characters using Unicode character databases. In this database, there are character properties of all characters. To use this modules, we need to import the unicodedata module in our code. import unicodedata Unicode Database Methods Some modules of the unicodedata module are described here. Module (unicodedata.lookup(name)) − This method is used to lookup the characters by name. When the name is valid, it should return the character. Otherwise it will raise the KeyError. Module (unicodedata.name(chr[, default]))− This method is used to return the name of the given ...
Read MorePython program to find Union of two or more Lists?
Union operation means, we have to take all the elements from List1 and List 2 and all the elements store in another third list. List1::[1, 2, 3] List2::[4, 5, 6] List3::[1, 2, 3, 4, 5, 6] Algorithm Step 1: Input two lists. Step 2: for union operation we just use + operator. Example code # UNION OPERATION A=list() B=list() n=int(input("Enter the size of the List ::")) print("Enter the Element of first list::") for i in range(int(n)): k=int(input("")) A.append(k) print("Enter the Element of second list::") for i in range(int(n)): ...
Read MorePython Internet String Preparation
To identify different things in the internet, it is necessary to compare different identification for equality. The comparison procedure depends on the application domain. For an example, some things are case-insensitive etc. To check these kind of information stringprep is used. The RFC 3454 defines the procedure to prepare the Unicode strings before transmitting through the wire. After going through the preparation procedure, they have a certain normalized form. The RFC defines a set of tables; these tables can be combined into profiles. For an example there is a profile of stringprep is nameprep. In the nameprep, there are internationalized ...
Read MorePython program to find Intersection of two lists?
Intersection operation means, we have to take all the common elements from List1 and List 2 and all the elements store in another third list. List1::[1, 2, 3] List2::[2, 3, 6] List3::[2, 3] Algorithm Step 1: input lists. Step 2: first traverse all the elements in the first list and check with the elements in the second list. Step 3: if the elements are matched then store in third list. Example code #Intersection of two lists def intertwolist(A, B): C = [i for i in A if i in B] ...
Read MoreSecond most repeated word in a sequence in Python?
The string is given, our task is to find out the second repeated word. Here we Counter(iterator) for creating dictionary which contains word as key and its frequency as value. Algorithm Step 1: Create user define list. Step 2: Then convert list into a dictionary. Step 2: Next get the values and sort them in descending order. Step 3: Then the second element is the second largest value. Step 4: Next again traverse whole dictionary and display key whose value is equal to second largest element. Example code # To print Second most repeated word in a ...
