You can create an objectUsing new keyword.Sample obj = new Sample();Using the newInstance() method and Class.forName() method.Sample obj2 = (Sample) Class.forName("Sample").newInstance();Using the clone() method by implementing Cloneable Interface (marker).Sample obj3 = (Sample) obj1.clone();Using class loader.Object obj4 = Sample.class.getClassLoader().loadClass("Sample");Using the constructor class from lang.reflect.Class cls = Sample.class; Constructor obj = cls.getDeclaredConstructors()[0]; Sample obj5 = (Sample) obj.newInstance();

An object is created from a class using the new keyword. There are three steps when creating an object from a class −Declaration − A variable declaration with a variable name with an object type.Instantiation − The 'new' keyword is used to create the object.Initialization − The 'new' keyword is followed by a call to a constructor. This call initializes the new object.Examplepublic class Sample {    public static void main(String args[]){       Sample s = new Sample();    } }

Packages are similar to namespaces in C#.

An object is created from a class. In Java, the new keyword is used to create new objects. There are three steps when creating an object from a class − Declaration − A variable declaration with a variable name with an object type. Instantiation − The 'new' keyword is used to create the object. Initialization − The 'new' keyword is followed by a call to a constructor. This call initializes the new object. Following is an example of creating an object − Example Live Demo public class Puppy { public Puppy(String name) { ... Read More

A constructor is a special method in Java that is used to initialize objects. It gets called when an instance of a class is created. The constructor has the same name as the class and does not have a return type. The question is whether a constructor can be declared or made final in Java? The answer is no. Let's understand why. Why can't we declare a Java Constructor "final"? In Java, the final keyword is used to restrict modification of the members of a class (methods and variables). For example, a final method of a class cannot be overridden ... Read More

No, constructors are not inherited in Java.

No, the constructor does not return any value. While declaring a constructor you will not have anything like a return type. In general, the Constructor is implicitly called at the time of instantiation. And it is not a method, its sole purpose is to initialize the instance variables.Read more about constructors: Java Constructors Example public class Sample{ public Sample(){ System.out.println("This is a constructor"); } public static void main(String args[]){ ...

No, you cannot have both this() and super() in a single constructor.

Constructors are similar to methods but, They do not have any return type. The name of the constructor is same as the name of the class. Every class has a constructor. If we do not explicitly write a constructor for a class, the Java compiler builds a default constructor for that class. Each time a new object is created, at least one constructor will be invoked. A class can have more than one constructor. this() and super() are used to call constructors explicitly. Where, using this() you can call the current class’s constructor and using super() you can ...

Java 8 introduces a new concept of default method implementation in interfaces. This capability is added for backward compatibility so that old interfaces can be used to leverage the lambda expression capability of Java 8. For example, ‘List’ or ‘Collection’ interfaces do not have ‘foreach’ method declaration. Thus, adding such method will simply break the collection framework implementations. Java 8 introduces default method so that List/Collection interface can have a default implementation of foreach method, and the class implementing these interfaces need not implement the same.
