Multitasking Definition: The concept of executing multiple functionalities simultaneously is known as multitasking.   Example program: Class MSD { Fun1 () { } Fun2 () { } Fun 3() { } Public static void main (string args [ ]) { MSD s1 = new MSD (); S1. Fun 1(); S1. Fun 2 (); S1. Fun…


User-defined exceptions All these times we have been using predefined exception classes whose objects were created by JVM, because of predefined logical errors. In a similar manner, we can define our own exceptions classes whose objects will be created when user defined logical errors occur Strictly speaking, the user defined logical error is not a…


Definition of Finally keyword:   The finally keyword ensures that all the statements present inside the block finally block are compulsory executed. What is the need of finally block? Sometimes, some statements inside a try block need to be executed compulsorily whether exceptions occur or not.   Example: Try { Get connection to a printer…


Try-catch block   Point to remember regarding try- catch:  Whenever try block has n number of blocks, then if an exception object is created, the order of preference of catch blocks is the order in which they are present below the try block.   Consider the following scenarios: Try { ==== } Catch (exceptions e)…


Throws keyword and Constructors   Definitely, we can use throws keyword with constructors because constructors may have many numbers of statements which are proven to generate exception class objects.   Class Edemo4 { Int    I, j, k; Edemo4 (int x, int y) throws Exception { I=x; j=y; K – i/j; } } Class Test4 {…


Defining functions with a return type   Whenever we can define a function with a return data type, then we should not close the function without returning the value of the return data type. So a blind rule we follow is to declare a variable of the return data type as the first statement inside…


Arrays – In java arrays are treated as objects. While using arrays we create objects for arrays where a class is nonexistent. Whenever JVM encounters [] It understands that it has to create an object. Thus array object can be created without using the new operator. Whenever JVM encounters it understands that it has to create an…
