K BLOCK, KIDWAI NAGAR (near Alankar Guest House), Kanpur. by: Vinod Khare(MCA,M.Sc.,B.Ed.) (cell :9336061496) ICSE Computer Applications-2016-17 (Suggestions to get best marks) Here s an idea about how to answer the two sections. Section A - Each question carries the marks specified in front of it. Read the question carefully and answer only how much is asked. For example, if one difference is asked, then write only one. But if you are not sure of the answer then write more. The one that is correct would be marked. You can also keep the following points in mind while answering this section: Write to the point precise answers. Use keywords while answering definitions, differences, etc. For example, Constructor is a member function with the same name as class and no return type. (Here, no return type and name same as class are important keywords). Write differences, if asked, making two columns. Write example of each, if you know Do not leave any answer. Even if you don t know, write something as marking is not negative. While attempting write the output type of questions, show the Dry Run working. While attempting solve type of questions based on operators, show all the steps. Read the data types used in the arithmetic expression carefully for showing the final answer. Learn the definitions, syntax and return type of various string, mathematical and character related functions very well. Should know the three loops well and their inter conversions. Should know the definitions and syntax of all if structures and switch-casedefault well and their inter-conversions. Study ternary operator. Learn the definitions and example of OOP principles. Theory is important for this section. Section B: The marking in this section is step-wise so need not worry. Plan the program before you start writing as can t afford to waste time in canceling and re-writing. Write variable description or comments for each program. Don t forget as it carries marks. Read the question carefully and do not forget any step. So write the program step by step keeping all points in mind. Try to indent the program as it makes it neat. Study if structures, loops, arrays and strings and functions well for this section. Also revise sorting and searching methods. Must know mathematical and string functions as they might be needed for such questions. Careful and correct answering may lead to a full score of 100. Best wishes for your exams. by: vInod khARaY TOPIC TO STUDY FROM WHOLE SYLLABUS FOR SECTION A(40 MARKS) OBJECT definition and examples creating and explaining meaning of an object why class is an object factory relation between class and object java is a case sensitive language explain why a class is considered as composite data type object as instance of a class CONCEPT OF OOPS encapsulation its example and their attribute inheritance, extends keyword, sub and super class polymorphism and its example abstraction or data hiding difference between object and class Features of Java like platform independent, security, open source ,write once run anywhere(WORA) TYPES OF JAVA PROGRAM applets and standalone/application program JAVA COMPILATION PROCESS interpreter and compiler byte code Java virtual machine source code and object code COMMENTS single and multiple line comments import statements and its use package , default package(java.lang) 1
