ICSE − Q & A

Hi guys,,, Any tips for computer exam....
Will any questions be repeated from previous years question papers theory,programs?

Also please upload the most important programs

Are comments important while writing programs?

how read a character from user input in java

If there are any syntax errors in the output questions in the paper, should we just ignore them and solve the program segment?

Eco tips please

Many people messaged and asked for this : So here is the computer applications study pattern :
There are topics in Computer apps : 
1) Revision of 9th grade : OOP , History and Dev of Java , Data Types, Operators/Expressions and General programming and decision making.
2) Loops
3) Library Classes 
4) Strings
5) Arrays
6) Scanner Class
7) Functions
8) Constructors
9) Class as a user defined data type
10) Encapsulation / Inheritance

Topics 1) , 3) , 10 ) and 9) - Is theory only - Do these thoroughly.
Others have theory + Programs 

Today : Read the text book and WRITE DOWN all definitons - Yes all , there may be 90-100 , write them down - every single one. Just light read the text book. Don't even touch programs. So the theory must be done by today.

Tomorrow : Wake up at 5:30 in the morning and solve the previous year theory questions - You all should have a 10 year book. This should be done by 9 am. Then start with programs , read all examples in your text book and understand them : In 2 years of learning Java, you should have a strong grip on this. I recommend writing down the syntax of Bubble Sort / Selection Sort and Binary search down. Just mug it up if you don't understand - sure shot question will come on this.Then go through the 10 year book and read only the questions of the programs. If you get it in 1st thought, leave it but if you don't get it : Write down only the algorithm. Don't waste time writing down the whole program from import java.util.*; to SOPln (Answer) ; Then come on respaper and solve some theory questions of other schools and glance over programs. Then go on to your computer and run the programs you found hard - by typing them out. 
Before sleeping - read all the notes you made. Have a good night sleep and wake up at 6  am and read all notes again , solve sample questions(theory) and learn the 3 syntax's I told you to do.
REMEMBER : Do NOT use functions out of scope such as .toCharArry() ;

Good Luck :)

Bio was sooooo easy!!!
Expecting atleast 97 or 98
And how about you guys?

can anyone explain what is variable description . plzzz

Which is the easiest way to memorize the precedence of operators?

Tips for computer exam:

I think time is now ripe to share these

Section I: (theory)

•	Attempt all questions(too obvious, but important)
•	Read all questions and their subparts properly and then answer them
•	In definition questions, always write an answer enough for a 2 mark question, not   more not less, History exam is already over.
•	Always try to quote examples, even if not asked
•	In output based questions, use ‘dry run’ method, it is by far the best method and gives accurate answers.(if u dont know, contact me)
•	Learn important packages and what classes they contain
•	Be very careful in increment/decrement questions. The slightest mistake can land u in trouble.
•	Dont exclude inheritance, encapsulation and error handling chapters, they are in syllabus 
•.      Get some output base ques here: http://www.respaper.com/krishanudutta/8319-pdf.html

Section II (Practical):

•	There should be a clear cut logic in your programs, so that the examiner dosen't have to break his head to understand  it.
•	Use neat handwriting, distinguish between uppercase and lowercase.
•	Use scanner or input through a fuction rather than using BufferedReader, it saves a huge lot of time.
•	It is a sin to forget the variable description after a program, you immediately lose a chunk of marks, even if your program if fool-proof.
•	Write the variable description just after the program, not at the end.
•	Just do as directed in the first question, don’t use your own creativity, variables or functions.
•	If you attempt the overloaded function question, be at your won risk, it takes most of your time.
•	Practice sufficient problems on series and pattern

Hope this helps. If u find any difficulties, u can always contact me in chat.
