A. Array Declarations(2 pts each). Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration. Array Declaration int[50] list; int size; Answer 1. 2. double[] list = new double[size]; int[] test = new int[-5]; 3. double[] sales = new double[25.5]; 4. 5. int x, y; char[x][y] board = new board[][]; B. Write the appropriate method headings using the provided method name for the following processes (2 pts each). 1. Calculate and return the sum of two decimal numbers - getSum. 2. Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed. 3. Given the radius of a circle, print the area of a circle - printArea. 4. Given a student's name and three test scores (of type int), print the student's name and average test score - printStudent Details. 5. Accept an integer, compute for the square of the number and return the String equivalent of the square of the number - makeString. A. Array Declarations(2 pts each).
