You can declare an array just like a variable −int myArray[];You can create an array just like an object using the new keyword −myArray = new int[5];You can initialize the array by assigning values to all the elements one by one using the index −myArray [0] = 101; myArray [1] = 102;You can access the array element using the index values −System.out.println("The first element of the array is: " + myArray [0]); System.out.println("The first element of the array is: " + myArray [1]); Alternatively, you can create and initialize an array using the flower braces ({ }): Int [] myArray = {10, 20, 30, 40, 50}
Read MoreWhat is the try block in Java?
A try/catch block is placed around the code that might generate an exception. Code within a try/catch block is referred to as protected code, and the syntax for using try/catch looks like the following –Syntaxtry { // Protected code } catch (ExceptionName e1) { // Catch block }The code which is prone to exceptions is placed in the try block. When an exception raised inside a try block, instead of terminating the program JVM stores the exception details in the exception stack and proceeds to the catch block.
Read MoreWhat is Deserialization in Java?
After a serialized object has been written into a file, it can be read from the file and Deserialized that is, the type information and bytes that represent the object and its data can be used to recreate the object in memory.Exampleimport java.io.*; public class DeserializeDemo { public static void main(String [] args) { Employee e = null; try { FileInputStream fileIn = new FileInputStream("/tmp/employee.ser"); ObjectInputStream in = new ObjectInputStream(fileIn); e = (Employee) in.readObject(); in.close(); ...
Read MoreWhat is the difference between Serialization and Deserialization in Java?
Serialization Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object's data as well as information about the object's type and the types of data stored in the object.Exampleimport java.io.*; public class SerializeDemo { public static void main(String [] args) { Employee e = new Employee(); e.name = "Reyan Ali"; e.address = "Phokka Kuan, Ambehta Peer"; e.SSN = 11122333; e.number = 101; try { ...
Read MoreWhich method must be implemented by all threads in Java?
While creating a thread class we must override the run() method of the Thread class. This method provides an entry point for the thread and you will put your complete business logic inside this method.Exampleclass ThreadDemo extends Thread { private String threadName; ThreadDemo( String name) { threadName = name; System.out.println("Creating " + threadName ); } public void run() { System.out.println("Running " + threadName ); try { for(int i = 4; i ...
Read MoreWhere and how can I create a private constructor in Java?
We can use a private contractor in a Java while creating a singleton class. The Singleton's purpose is to control object creation, limiting the number of objects to only one. Since there is only one Singleton instance, any instance fields of a Singleton will occur only once per class, just like static fields. Singletons often control access to resources, such as database connections or sockets.ExampleThe easiest implementation consists of a private constructor and a field to hold its result, and a static accessor method with a name like getInstance().The private field can be assigned from within a static initializer block ...
Read MoreWhat does the method ensureCapacity(int, minCapacity) do in java?
The ensureCapacity(int minCapacity) method of the class java.util.ArrayList increases the capacity of this ArrayList instance, if necessary, to ensure that it can hold at least the number of elements specified by the minimum capacity argument.Exampleimport java.util.ArrayList; public class ArrayListDemo { public static void main(String args[]) { ArrayList arrlist = new ArrayList(5); arrlist.add(10); arrlist.add(50); arrlist.add(30); arrlist.ensureCapacity(15); for (Integer number : arrlist) { System.out.println("Number = " + number); } } }OutputNumber = 10 Number = 50 Number = 30
