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.
In java how the class containing main is executed with out creating an object?
You may know that static methods in Java are executed even before the constructor of that class are called. Similarly, since the main method is static it gets executed first even before the others methods of the class are called. Since it is being called before the constructor, logically speaking you cannot have objects of that class.
What is a java deconstruct?
Every class has at least one it's ownconstructort. Constructor creates a instance for the class. Constructor initiates (initialize) something related to the class's methods. Constructor is the method which name is same to the class. But there are many difference between the method (function) and the Constructor. In this example we will see that how to to implement the constructor feature in a class. This program is using two classes. First class is another and second is the main class which name is Construct. In theConstruct class two objects (a and b) are created by using the overloaded another Constructor by passing different arguments and calculated the are of the different rectangle by passing different values for the another constructor.
What is nextint in java?
"nextInt()" gets the next integer entered by the user.here is a simple code-import java.util.Scannerpublic class {bhal bhalScanner in = new Scanner (System.in)int x;System.out.println ("enter a number");x=in.nextInt();}here "in" is an object of the "Scanner" class and "nextInt()" gets the next integer from the user for "in" object and assigns it to "x" variable which is declared as int variable before.
What is object in programming?
Object in context of a class is the root of the class hierarchy in Java in the java.lang package.Every class has Object as a superclass whether it's explicit or not. All objects, including arrays, implement the methods of this class.

How objects are created?
By using the new keyword. Whenever you use the new keyword along with a class name, an object of that class gets created. Ex: Ferrari obj = new Ferrari(); The above line creates an object of type "Ferrari" and the constructor inside the class named Ferrari would get invoked and an object of type Ferrari would get created.
When does the memory created for an object?
Memory for a Java object gets created when the object is instantiated. For example private String name = "rocky"; At the end of this statement the memory for the string object name gets created in the memory.
When a derived class object is deleted which gets deleted first - the base class object or the derived class object?
When there is no further use of derived class obect in execution sequence then It gets deleted. calling of distructor sequence is reverse of constructor calling sequence ,so first derived class obect deleted than base class obect.
The energy an object gets from its motion is?
The energy an object gets from its motion is called kinetic energy. Kinetic energy is dependent on the speed and mass of an object.

What is it called when light energy strikes an object and changes to heat energy?
This process is called absorption. The object absorbs the light energy, which then gets converted into heat energy.

Why tire pump gets hot when it is used to inflate an object?
Because of the friction created by the compressor piston
What is it called when a neutral object gets a temporary charge?
When a neutral object gets a temporary charge, it is called "static electricity." This can occur through processes like friction or induction, where electrons are temporarily transferred between objects, leading to one object becoming positively charged and the other becoming negatively charged.
What is object program?
friend, I'll explain an object in the context of class in CPP programming. after the definition of a class , you can define an object belonging to that class. for example, class student { int rollno; char name[10]; void getdetails() {cout<<"enter the roll number and name of the student"; cin>>rollno; gets(name); } void showdata() {cout<<"the name is"<<name<<"and the rollnumber is" <<rollno; }} sara; here sara is an object belonging to class student. object sara can use the function getdetails() to get values to the identifiers rollno and name. " Class is a group of objects with similar characters ( eg: rollno , name) and behaviour ( ie., the member functions-getdetails and showdata)" " An object is a an entity with certain characters and behaviour" here object sara denotes a student sara. now, you can create another object rahul to the class student by typing the code- student rahul;
What is nextint in java?
"nextInt()" gets the next integer entered by the user.here is a simple code-import java.util.Scannerpublic class {bhal bhalScanner in = new Scanner (System.in)int x;System.out.println ("enter a number");x=in.nextInt();}here "in" is an object of the "Scanner" class and "nextInt()" gets the next integer from the user for "in" object and assigns it to "x" variable which is declared as int variable before.
