SYLLABUS CLASS X





                  There will be one written paper of two hours duration carrying 100 marks and Internal Assessment of 100 marks.
                  The paper will be divided into two sections A and B.
                  Section A (Compulsory-40 marks) will consist of compulsory short answer questions covering the entire syllabus.
                  Section B (60 marks) will consist of questions that will require detailed answers. There will be a choice of questions in
                  this section
                                                            THEORY-100 Marks
                  1. Revision of Class IX Syllabus
                  (i) Introduction to Object-Oriented Programming concepts, (ii) Elementary Concept of Objects and Classes, (iii) Values
                  and Data types, (iv) Operators in Java, (v) Input in Java, (vi) Mathematical Library Methods, (vii) Conditional constructs
                  in Java, (viii) Iterative constructs in Java, (ix) Nested for loops.
                  2. Class as the Basis of all Computation
                  Objects and Classes
                  Objects encapsulate state and behaviour—numerous examples; member variables; attributes or features. Variables
                  define state; member methods; Operations/methods/messages/ methods define behaviour.
                  Classes as abstractions for sets of objects; class as an object factory; primitive data types, composite data types. Variable
                  declarations for both types; difference between the two types. Objects as instances of a class.
                  Consider real-life examples for explaining the concept of class and object.

                  3. User-defined Methods
                  Need of methods, syntax of methods, forms of methods, method definition, method calling, method overloading,
                  declaration of methods,
                  Ways to define a method, ways to invoke the methods—call by value [with programs] and call by reference [only
                  definition with an example], Object creation—invoking the methods with respect to use of multiple methods with
                  different names to implement modular programming, using data members and member methods, Actual parameters
                  and formal parameters, Declaration of methods-static and non-static, method prototype/signature, - Pure and impure
                  methods, pass by value [with programs] and pass by reference [only definition with an example], Returning values
                  from the methods, use of multiple methods and more than one method with the same name (polymorphism - method
                  overloading).

                  4. Constructors
                  Definition of Constructor, characteristics, types of constructors, use of constructors, constructor overloading.
                  Default constructor, parameterized constructor, constructor overloading., Difference between constructor and method.
                  5. Library classes
                  Introduction to wrapper classes, methods of wrapper class and their usage with respect to numeric and character data
                  types. Autoboxing and Unboxing in wrapper classes.
                  Class as a composite type, distinction between primitive data type and composite data type or class types. Class may
                  be considered as a new data type created by the user, that has its own functionality. The distinction between primitive
                  and composite types should be discussed through examples. Show how classes allow user-defined types in programs.
                  All primitive types have corresponding class wrappers. Introduce Autoboxing and Unboxing with their definition and
                  simple examples.
                  The following methods are to be covered:
                  int parseInt(String s),
                  long parseLong(String s),
