In Java, a multi-dimensional array is nothing but an array of arrays.2D array − A two-dimensional array in Java is represented as an array of one-dimensional arrays of the same type. Mostly, it is used to represent a table of values with rows and columns −Int[][] myArray = {{10, 20, 30}, {11, 21, 31}, {12, 22, 32} }In short, a two-dimensional array contains one-dimensional arrays of elements. It is represented by two indices where the first index denotes the position of the array and the second index represents the position of the element within that particular array − Example ...

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.
