Sorting a numerical Array

[valaree k.]

Hello everyone!
I am working on a small project for school with the following requirements:
- Create a program that requests the user to enter five integers
- Place these values into an array called myArr
- Type any sorting method into this program that will sort the array myArr
Here is my code:

  
public class CIS140Exam3Prog1
{  
  static BufferedReader keyboard =
      new BufferedReader(new InputStreamReader(System.in));
    //Main method
  public static void main(String[] args) throws Exception {
 
    //declarations
    int[] myArr = new int[5];
    int i = 0;
    
     // obtain user input and give the values to myArr[] 
    for (i = 0; i < myArr.length; i++) 
 {
      System.out.print("Enter integer " + (i + 1) + ": ");
      myArr[i] = Integer.parseInt(keyboard.readLine());
      System.out.println("");
  }   
       //  print the contents of myArr[] before sorting
    for (i = 0; i <= myArr.length - 1; i++)
      System.out.println(myArr[i]+" ");
      System.out.println();
 
    System.out.println("After calling the sorting method \n");
   
    insertionSort(myArr, myArr.length);  // this line is causing the out of bounds exception
    Arrays.sort(myArr, myArr.length - 1, myArr.length); // another failed line at sorting myArr[] 
    System.out.println(myArr);  // displays hash code
 }
   // insertion sort method
  public static void insertionSort(int[] list, int listLength) 
 {
    {
      int frstOutOfOrder, location, temp;
      for (frstOutOfOrder = 0; frstOutOfOrder < listLength; frstOutOfOrder++)
        if (list[frstOutOfOrder] < list[frstOutOfOrder] - 1) {
          temp = list[frstOutOfOrder];
          location = frstOutOfOrder;
          do 
        {
            list[location] = list[location - 1];
            location--;
        }
          while (location > 0 && list[location - 1] > temp);
          list[location] = temp;
        }
     }
   }
 }

This is the exception I am getting:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 5
at eldervaleriecis140.CIS140Exam3Prog1.main(CIS140Exam3Prog1.java:30) 

I am lost =(
Any help or suggestions would be much appreciated!

Halo,

The java.lang.ArrayIndexOutOfBoundsException means that your are trying to access an array object with an index larger than the current data inside the array.

Array in Java is zero indexed, which means the array index start from zero. So if you have five items in it (array length = 5) it means the index if from 0 to 4. In your code you have five items in the array, this mean the maximum array index is 4.

To fix the error in your code you have to change the for loop condition check in insertionSort() method.
