The new keyword

                         

The new keyword in java programming language is used to create a new instance of a class or an array. Keywords are basically reserved words which have specific meaning relevant to a compiler. The new keyword allocates new objects and initialize them.

Syntex:  Here is the syntax that displays how to create an instance of a class or an array by using the new operator.

Creating a simple java object (non array object) by using the new operator.

String sName = new String();

Creating an array object by using the new operator.

Array arr = new Array();

Note: Here are some points that must be considered while creating an instance of a class or an array.

  • The argument that follows the new keyword must be a class name followed by a series of constructor arguments having parentheses.

  • The collection of arguments must be same as the signature of a constructor for the class.

  • The variable type on the left side of the assignment operator must be compatible with the class or interface which is being instantiated.
