3. Trace the following three sections of code in the tables below. When the name of an array is given in the trace chart, show the values of all elements of the array public class Test2{ public static void main(String[ ] args) { IPART A int[ ] arr = (10,20,30}; int num=changeltfarr1); IPART B int] arri = (10,20,30}; changeOne(arri,1); IPART C int] arr2 = (10,20,30); intj newArr = changeTwo(arr2); }/ end main static int changet(int n) { n = n*50; return n;}

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

class Main {             // this function will return the number elements in the given range             public static int getCountInRange(int[] array, int lower, int upper)             {                         int count = 0; // to count the numbers                         // this loop will count the numbers in the range                         for (int i = 0; i < array.length; i++)                         {                     // if element is in the range                                     if (array[i] >= lower && array[i] <= upper)                                                 count++;                         }                                                 return count;             }               public static void main(String[] args)             {         // array         int array[] = {1,2,3,4,5,6,7,8,9,0};                         // ower and upper range                         int lower = 1, upper = 9;                         // throwing an exception…
