4.buble sort.

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?

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 :)
