Java is an object-oriented programming language and object creation is a fundamental aspect of object-oriented programming. The new keyword in Java is an essential part of creating objects. Let\u2019s learn how the new keyword in Java is used to create objects, what happens when an object is created using the new Keyword in Java, and some important things to keep in mind when using the new Keyword in Java to create objects. We will also discuss some examples for a better understanding of the topic.<\/p>\n

What is new Keyword in Java<\/h2>\n

The new keyword in Java is used to create an instance of a class, also known as an object. It is used to allocate memory for an object and call the constructor of the class to initialize the object’s state.<\/p>\n

The new keyword is followed by the constructor of a class, which sets the initial values for the object’s fields and performs any other necessary setup. The constructor is a special method that is called automatically when an object is created. Without the new keyword, an object cannot be created and the constructor cannot be called.<\/p>\n

Process of Object Creation in Java<\/h3>\n
The process of object creation in Java involves several steps:<\/p>\n
    \n
  1. \n
    Declare a variable:<\/strong> A variable is declared with the class type of the object that needs to be created. The variable does not hold the object itself, but it holds the reference to the object.<\/p>\n
    Syntax:<\/strong><\/p>\n
    ClassName objName;<\/code><\/pre>\n<\/li>\n
  2. \n
    Allocate memory:<\/strong> The new keyword is used to allocate memory for the object on the heap. The memory is reserved for the object’s fields and methods.<\/p>\n
    Syntax:<\/strong><\/p>\n
    ClassName objName = new ClassName();<\/code><\/pre>\n<\/li>\n
  3. \n
    Initialize the object:<\/strong> The constructor of the class is called to initialize the object’s state. The constructor sets the initial values for the object’s fields and performs any other necessary setup.<\/p>\n<\/li>\n<\/ol>\n
