In java, fix the code so
1.) User can only input integers 1-10, and if any other integer then it should throw an exception, print out invalid input please try again, and allow the user to reinput.
2.) If user inputs random stirng then it should do the same above ^ except for R to refill array and q to quit the program.
import java.util.*;
public class KSmallTester {public final static int SIZE_OF_ARRAY = 10;
public final static String PROMPT = "Please enter an integer k, 1<=k<=" +
SIZE_OF_ARRAY + ", or 'R' to refill the array: ";
public static void printArray(int[] array) {
System.out.println("");
System.out.print("array = [");
for (int i=0; i < SIZE_OF_ARRAY-1; i++)
System.out.print(""+ array[i]+" | ");
System.out.println(""+ array[SIZE_OF_ARRAY-1]+"]");
System.out.println("-------------------------------------------------"
+ "-------------------");
}
public static void randFillArray(int[] array) {
Random random = new Random();
for (int i=0; i < SIZE_OF_ARRAY; i++)
array[i] = random.nextInt(100);
}
public static void main(String argv[]) {
int k = 1, kthSmallest = 0;
int[] array = new int[SIZE_OF_ARRAY];
int[] arrayTmp = new int[SIZE_OF_ARRAY];
randFillArray(array);
printArray(array);
// ToDo: Read input k and print out the k-th smallest item of the array.
// Note that your program should allow finding k-th smallest item from an array
// continuously (i.e., more than once) , refilling the array, and exiting the
// program when typing in "Q" or "q".
String choice = null;
Scanner sc = new Scanner(System.in);
do
{
System.out.println(PROMPT);
choice =sc.nextLine();
if (choice.equalsIgnoreCase("R")) {
randFillArray(array);
printArray(array);
} else if (choice.equalsIgnoreCase("q")) {
System.out.println("Thank you for using");
System.exit(0);
}else {
int kth = Integer.parseInt(choice);
//Create a deep copy of array
for (int i = 0; i < SIZE_OF_ARRAY;i++) {
arrayTmp[i] = array[i];
}
int kthSmall = KthSmallest.kSmall(kth, arrayTmp, 0, SIZE_OF_ARRAY -1);
System.out.println("Kth Smallest Elemnt : " + kthSmall);
}
}
while(choice!=null);
}
}
