Here we will see what are the differences between structures in C and structures in C++. The C++ structures are mostly like classes in C++. In C structure, all members are public, but in C++, they are private in default. Some other differences are listed below.C StructureC++ StructureStructures in C, cannot have member functions inside structures.Structures in C++ can hold member functions with member variables.We cannot initialize the structure data directly in C.We can directly initialize structure data in C++.In C, we have to write ‘struct’ keyword to declare structure type variables.In C++, we do not need to use ‘struct’ ...

You can lock a record, set of records, database table, table-space etc. and when we do we cannot change the locked values. Following are the types of locking in JDBC:Row and Key Locks: These are used to lock a particular row. Using these locks, you can achieve concurrency.Page Locks: These are used to lock a page. If you apply this, whenever the contents of a row changes, the database locks the entire page which holds the row. If you need to update/change large number of rows at once you can use this lock.Table Locks: You can lock a table using ... Read More

In this section we will see how to convert a number (integer or float or any other numeric type data) to a string.The logic is very simple. Here we will use the sprintf() function. This function is used to print some value or line into a string, but not in the console. This is the only difference between printf() and sprintf(). Here the first argument is the string buffer. where we want to save our data.Input: User will put some numeric value say 42.26 Output: This program will return the string equivalent result of that number like "42.26"AlgorithmStep 1: Take ...

In order to get file extension of file as a result of SQL query, you can use SUBSTRING_INDEX().The syntax is as followsselect substring_index(yourColumnName, '.', -1) as anyAliasName from yourTableName;To understand the above syntax, let us create a table. The query to create a table is as followsmysql> create table getFileExtensionDemo -> ( -> File_Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> File_Name text -> ); Query OK, 0 rows affected (0.53 sec)Insert some records in the table using insert command.The query is as followsmysql> insert into getFileExtensionDemo(File_Name) values('John.AllMySQLConcept.doc'); Query OK, 1 row affected (0.17 sec) mysql> ...

To return a shallow copy of the CopyOnWriteArrayList, use the clone() method.The syntax is as follows:public Object clone()To work with CopyOnWriteArrayList class, you need to import the following package:import java.util.concurrent.CopyOnWriteArrayList;The following is an example to implement CopyOnWriteArrayList class clone() method in Java:Example Live Demoimport java.util.concurrent.CopyOnWriteArrayList; public class Demo { public static void main(String[] args) { CopyOnWriteArrayList arrList = new CopyOnWriteArrayList(); arrList.add(30); arrList.add(90); arrList.add(80); arrList.add(70); arrList.add(90); arrList.add(100); arrList.add(120); System.out.println("CopyOnWriteArrayList = " + arrList); System.out.println("Cloned CopyOnWriteArrayList = " + arrList.clone()); } }OutputCopyOnWriteArrayList = [30, 90, 80, 70, 90, 100, 120] Cloned CopyOnWriteArrayList = [30, 90, 80, 70, 90, 100, 120]
The min() method of the DoubleStream class returns an OptionalDouble describing the minimum element of this stream, or an empty OptionalDouble if this stream is empty.The syntax is as follows:OptionalDoublemin()Here, OptionalDouble is a container object which may or may not contain a double valueTo use the DoubleStream class in Java, import the following package:import java.util.stream.DoubleStream;Create a DoubleStream and add elements to the stream:DoubleStream doubleStream = DoubleStream.of(67.9, 89.9, 10.5, 95.8, 49.6);Get the maximum element from the DoubleStream:OptionalDouble res = doubleStream.max();The following is an example to implement DoubleStream min() method in Java:Example Live Demoimport java.util.OptionalDouble; import java.util.stream.DoubleStream; public class Demo { public ...
