This program is asking to enter number of elements in first prompt and in for loop the numbers are being stored fom the entered number to 1 in reverse suppose we enter 3 in first prompt then array will store 3,2,1. and in second prompt we have to enter the value we want to retrieve from array .
If i type 3 for first prompt compiler asks me to enter size of array and in next prompt which value i want to retrieve from array.
If i type 7 for first prompt compiler asks me to enter size of array and in next prompt which value i want to retrieve from array.
If i type 12 for first prompt i got exception ArrayIndexOutOfBoundException as size of array is fixed by 10 .
If i type 20 for first prompt i got exception ArrayIndexOutOfBoundException as size of array is fixed by 10 .
If i type 3 for first prompt compiler will ask me size of array and in next prompt which value i want to retrieve from array.
When i type 10 for first prompt and 3 for second prompt i got 7 as output.
When i type 10 for first prompt and 7 for second prompt i got 3 as output.
When i type 10 for first prompt and 12 for second prompt i got an exception ArrayIndexOutOfBoundException.
When i type 10 for first prompt and 20 for second prompt i got an exception ArrayIndexOutOfBoundException.

So this is all I have done
right now. Next steps:
1. Create a method called "printArray" which would put the code
: for(int i = 0; i < myArray.length; i++)
System.out.println(myArray[i]); at the bottom of that screen and
put it into a method and then call it.
2. Create another method thats going to count all the numbers
that are evenly divisible by 10 and call the method whatever you
like.

Step 4: Add code that discards any extra entries at the propmt that asks if you want to enter another score. Notes from professor: For Step 4, add a loop that will validate the response for the prompt question: "Enter another test score? (y/n): " This loop must only accept the single letters of ‘y’ or ‘n’ (upper case is okay). I suggest that you put this loop inside the loop that already determines if the program should collect...

write a program which include a class containing an array of words (strings).The program will search the array for a specific word. if it finds the word:it will return a true value.if the array does not contain the word. it will return a false value. enhancements: make the array off words dynamic, so that the use is prompter to enter the list of words. make the word searcher for dynamic, so that a different word can be searched for each...

You will need to think about problem solving. There are several multi-step activities. Design, compile and run a single Java program, StringEx.java, to accomplish all of the following tasks. Add one part at a time and test before trying the next one. The program can just include a main method, or it is neater to split things into separate methods (all static void, with names like showLength, sentenceType, lastFirst1, lastFirst), and have main call all the ones you have written...

With a Scanner object created as follows, what method do you use to read an int value? Scanner input = new Scanner(System.in); A. input.int(); B. input.nextInt(); C. input.integer(); D. input.nextInteger(); What is the output of the following code? x = 0; if (x > 0) System.out.println("x is greater than 0"); else if (x < 0) System.out.println("x is less than 0"); else System.out.println("x equals 0"); A. x is greater than 0 B. x is less than 0 C. x equals 0...

I have the following java-program, that creates a random walk
starting at (0,0) and continuing until x or y is greater than
abs(n).
First: I get an error, when I try closing the Scanner by
inserting "reader.close(); " in line 28. It says "Unreachable
code". How can I fix that?
Second: Is it possible to create a different colour for the
StdDraw.point when it reaches a point on one of the edges "n+1" or
"n-1" ?

Exercise 1): take the program “InteractiveCounting” (attached). Your task is to change the implementation of both the “ReadInput” and the “Count” classes. Currently these classes extends Thread. You should now use the Runnable interface to implement the thread. The output of the program should not change. I have also attached the class ThreadType2 to give you a working example on how to implement a thread using the Runnable interfacethe program is here package threadExamples; import java.util.Scanner; public class InteractiveCounting {...
So this is all I have done
right now. Next steps:
1. Create a method called "printArray" which would put the code
: for(int i = 0; i < myArray.length; i++)
System.out.println(myArray[i]); at the bottom of that screen and
put it into a method and then call it.
2. Create another method thats going to count all the numbers
that are evenly divisible by 10 and call the method whatever you
like.
