Can we create an array of objects for a class having default constructor Justify your answer?
See example code below. #include <iostream> class x { private: // Members. static int counter; int data; public: // Default constructor and destructor. x():data(++counter){printf("Object %d created!\n",data);} ~x(){printf("Object %d destroyed!\n",data);} // other members omitted for brevity... }; // Initialise static counter. int x::counter=0; int main() { // Instantiate an array of 10 objects. x arr[10]; // .. do some work with the array .. return( 0 ); // The array falls from scope, destroying the objects. } Example output: Object 1 created! Object 2 created! Object 3 created! Object 4 created! Object 5 created! Object 6 created! Object 7 created! Object 8 created! Object 9 created! Object 10 created! Object 10 destroyed! Object 9 destroyed! Object 8 destroyed! Object 7 destroyed! Object 6 destroyed! Object 5 destroyed! Object 4 destroyed! Object 3 destroyed! Object 2 destroyed! Object 1 destroyed!
This key word causes an object to be created in memory?
To instantiate a object, we use the new keyword in Java, which creates an object in memory.
What is object in java programming?
In java object is an instance of a class. Objects are created using the new keyword. When you use the new keyword along with a class name, an object of that class would get created. Ex: Ferrari obj = new Ferrari(); Here a new object of Ferrari gets created. A constructor of the class Ferrari would get invoked during the object creation.

How does the final keyword affect the behavior of Object type in Java?
In Java, the final keyword specifies that the object created cannot be further redefined or derived.
Define dangling if in terms of java?
A dangling reference is less problematic in Java, because the garbage collector will eventually delete any object that is unreachable. So, even if one object has a reference to a second object, and the second has a reference to the first object, they would eventually be destroyed if they are unreachable from the objects referenced on the stack.A dangling reference is less problematic in Java, because the garbage collector will eventually delete any object that is unreachable.

.....will be automatically Invoked when an object is created?
The Class object is automatically created by the JVM when an object is created. The Class object provides information about the Class and is primarily used by the IDEs and factory classes. The method that is automatically called when an object is created is called a constructor. In Java, the constructor is a method that has the same name as the class.
Can you initialize an object without constructor in java?
No. if you wish to create an object that you plan on using in a java program then the answer is NO. You cannot initialize an object of a Java class without calling the constructor.
