Hello, everyone.

I'm writing an extremely simple "Poker" type of game but I keep getting an error.

The code is supposed to do the following things; Prompt the user to enter 7 integers in the range 1 to 13 (inclusive), display a table of frequencies of the integers from 1 to 13, find the integer that occurs most frequently, and finally check if the 7 integers contain a continuous sequence of 5 or more.

Where the code messes up is at the boolean and where I try to return i. What's going wrong?

import java.util.Scanner; public class Poker { public static void main(String[] args) { int[] arrayOfInt1 = new int[7]; int[] arrayOfInt2 = new int[14]; readCards(arrayOfInt1); updateFreq(arrayOfInt1, arrayOfInt2); System.out.println("Number\tFrequency "); for (int i = 1; i < arrayOfInt2.length; i++) { System.out.println(i + "\t" + arrayOfInt2[i]); } int i = findMax(arrayOfInt2); System.out.println("The most frequent number is " + i + " with " + arrayOfInt2[i] + " occurrences."); int j = findSequence(arrayOfInt2); if (j > 0) { System.out.println("The sequence of 5 starts at " + j); } else System.out.println("There is no sequence of 5."); } public static void readCards(int[] paramArrayOfInt) { boolean bool = false; Scanner localScanner = new Scanner(System.in); do { System.out.print("Enter 7 integers (1-13): "); for (int i = 0; i < paramArrayOfInt.length; i++) { paramArrayOfInt[i] = localScanner.nextInt(); } bool = checkRange(paramArrayOfInt); }while (!bool); } public static int checkRange(int[] paramArrayOfInt) { int i = 1; for (int j = 0; j < paramArrayOfInt.length; j++) { if ((paramArrayOfInt[j] < 1) || (paramArrayOfInt[j] > 13)) { i = 0; } } return i; } public static void updateFreq(int[] paramArrayOfInt1, int[] paramArrayOfInt2) { for (int i = 0; i < paramArrayOfInt1.length; i++) paramArrayOfInt2[paramArrayOfInt1[i]] += 1; } public static int findMax(int[] paramArrayOfInt) //find integer that occurs most often { int i = paramArrayOfInt[0]; int j = 0; for (int k = 1; k < paramArrayOfInt.length; k++) { if (paramArrayOfInt[k] > i) { j = k; i = paramArrayOfInt[k]; } } return j; } public static int findSequence(int[] paramArrayOfInt) { //check if the integers contain a continuous sequence of 5 or more int i = 0; for (int j = 0; j < paramArrayOfInt.length; j++) { if (paramArrayOfInt[j] != 0) { i++; if (i >= 5) return j - i + 1; } else { i = 0; } } return -1; } }

I forgot to include the error I receive;
