Before getting into example, we should know what arrayblockingqueue is, it travels FIFO manner and first element going to live longest period of time and last element of the queue going to live short period of the time.This example demonstrate about How to find remaining capacity in ArrayBlockingQueue in androidStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken text view to showArrayBlockingQueue elements.Step 3 ... Read More
To remove \r from the text, you need to use REPLACE command. The syntax is as follows −UPDATE yourTableName SET yourColumnName=REPLACE(yourColumnName, ’\r’, ’ ‘);To understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table removeDemo -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Name text, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.79 sec)Now insert some records in the table using insert command. The query is as follows −mysql> insert into removeDemo(Name) values('John\rSmithCarol'); Query OK, 1 row affected (0.13 sec) mysql> insert into removeDemo(Name) values('LarryMike\rSam'); ...

For this, you can use REGEXP. Let us first create a table −mysql> create table DemoTable -> ( -> ClientCode varchar(100) -> ); Query OK, 0 rows affected (0.56 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values('Chris902'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable values('Robert_'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values('903'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('123_David'); Query OK, 1 row affected (0.21 sec)Display all records from the table using select statement ...

Before getting into example, we should know what ConcurrentLinkedQueueis, it is unbounded queue based on linked nodes. Multiple threads can access queue elements with safety. Elements travel based on queue strategy as FIFO and elements going to insert from tail. It does not allow null values.This example demonstrate about How to find element in android ConcurrentLinkedQueueStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken ... Read More
To compare two tables and return missing ids, you need to use a subquery. The syntax is as follows −SELECT yourFirstTableName.yourIdColumnName FROM yourFirstTableName WHERE NOT IN(SELECT yourSecondTableName.yourIdColumnName FROM youSecondTableName);To understand the above syntax, let us create a table with sample fields and then we will insert records. The query to create the first table −First_Tablemysql> create table First_Table -> ( -> Id int -> ); Query OK, 0 rows affected (0.88 sec)Now insert some records in the table using insert command. The query is as follows −mysql> insert into First_Table values(1); Query OK, 1 row affected (0.68 ... Read More

You can use format specifier. Following is the syntax −select str_to_date(yourColumnName, '%d/%m/%Y %h:%i %p') as anyAliasName from yourTableName;Let us first create a table −mysql> create table DemoTable -> ( -> DueDate varchar(100) -> ); Query OK, 0 rows affected (0.51 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values('11/02/2019 10:35'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable values('21/12/2018 12:01'); Query OK, 1 row affected (0.19 sec)Display all records from the table using select statement −mysql> select *from DemoTable;OutputThis will produce the following output −+------------------+ | DueDate ...

Before getting into example, we should know what ConcurrentLinkedDequeis, it is unbounded deque based on linked nodes. Multiple threads can access deque elements with safety.This example demonstrate about How to check element is available in android ConcurrentLinkedDequeStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code, we have taken text view to showConcurrentLinkedDequeelements.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.os.Build; import android.os.Bundle; import android.support.annotation.RequiresApi; ...
