QUESTION SOLVED

 

[davidktw]

Hi, i need some help from experts here for java.

1. How do i write so my program will take in 10 inputs from user and sort them in descending order?
2. Explain OOP and its features with examples of relevant java program.
3. Given n, the pattern contains n lines. The pattern contains asterisks and spaces alternately. The

sum of asterisks and spaces in each line is equal to n. The character at row i and column j is an

asterisk if i+j is an even number. Else, it is a space.

Write a program that takes a command-line argument N and prints an N-by-N pattern like the

one below.

Thanks for your time.

ok. For the first question i have done it in the pic attached. It will only save the 1st and 2nd input but will not save the rest.


For 2nd and 3rd question i have no ideas of whats going on. Maybe you can tell me the concept i will do the coding.

Thanks

3)
for(int i=0; i< n; i++){
for(int j=0; j<n; j++){
if((i+j)%2 == 0){
//print *
}
else print ' ';
}
}

1) your attached picture so small who can see?

I don't even understand what you are doing for question 1.

If the question asked for you to take 10 inputs from your user, why don't you use ask the user to enter 10 integers separated by whitespace. Then use your scanner and scan 10 times, put the 10 values into a 10 elements integer array and apply the sorting algorithm on the array ?

Question 2 is something you should go and read up. If I explain to you what is OOP, then what more do you need to explain ? Which school are you studying and why ain't you able to answer question 2 yourself ?

Question 3

Basically given a number N, a 2D pattern provided to you will have N rows and N columns. The pattern is made up of asterisk(*) and space( ).

You are told to print out such a 2D pattern where at position(j, i) in the 2D pattern, it will be an asterisk(*) if at row i and column j, i+j is an even number (divisible by 2) or space( ) if i+j is odd (not divisible by 2).

I think I have made the question a lot more clearer for you to understand.
