Write a Java program named searchForLastOccurence that : • Asks the user to enter an integer value that represents the size of an array of integers • Prompt the user to fill an array of integers • Asks the user to enter a key value The program should search for the last occurrence of the key value in the array and displays its position in the array, OR displays -1 if the value is not found in the array.

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive.  Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations.   Remember to validate the input and display an error message if the user inputs invalid data.  Documentation and the screenshot(s) of the results.  Example:  1  2  3 4  5  6 7  8  9 the result will be :  1  4  7 2  5  8 3  6  9

Consider the following program specification:   Write a program that will prompt the user for 10 integer values and stores them in an array.  The values entered by the user only be between 0 and 100 and the program should validate these appropriately.  The program should then: Display the average of the values Display the highest value in the array Display the lowest value in the array   Discuss how the values should be validated. What control structures could be used? Using eclipse

in C#, Visual Basic Write an app for Boston Airlines that allows a customer to reserve a seat on the airline’s only plane (capacity: 10 seats). Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message “Next flight leaves in 3 hours."
