This question already has answers here :
So in this context let's look at it in terms of the minimum and maximum values that the array access can have
So for the minimum value of i (0), we get i + numbers.length - 1 = 0 + 6 - 1 = 5
and for the maximum of i we either get 3 or numbers.length:
In the case of 3: i + numbers.length - 1 = 3 + 6 - 1 = 8
In the case of numbers.length we get i + numbers.length - 1 = 6 + 6 - 1 = 12
You need to make sure that the possible values that the array will iterate between is always going to give a value within the bounds of the array (as clearly this does not)
index exceeds array bound meaning?, It means that the index number is more than the array elements. An example: x=[1:10]. x(11). Your array has 10 elements but you try accessing the 11th element. An array-index out of bounds exception is a Java exception thrown due to the fact that the program is trying to access an element at a position that is outside an array’s limits or boundaries, hence the words “Out of bounds”. In other words, the program is trying to access an element at an index that is outside the array bounds.
Image that the array is like a chain of objects. You can always access any of those objects if you know its index. So in the case you have an array of length 9 that contains the first 9 positive integer you will have valid indexes through 0 to 8.
0 1 2 3 4 5 6 7 8
[1][2][3][4][5][6][7][8][9]
to print out the the values inside the array you could use:
for (int i = 0; i < values.length; i++) {
System.out.println(values[i]);
}
and if you would like to backward print it then you should start from it's last index and decrement the i until it greater or equal to the starting index of the array:
for (int i = values.length - 1; i >= 0; i--) {
System.out.println(values[i]);
}
Whenever you try to access an index that is out of the bound of valid indexes it will result to IndexOutofboundsException. So if you like to invoke any arithmetics with calculating the indexes be aware of the fact that you have only few valid values for it.
Index exceeds array bounds and some other mistakes, I don't really understand why the OP accepted this answer since it actually doesn't solve anything. Probably a case of accepting the first answer given regardless of Stay inside the bounds of the array in C programming while using arrays to avoid any such errors. C++ however offers the std::vector class template, which does not require to perform bounds checking. A vector also has the std::at() member function which can perform bounds-checking.
Tried to run
for (int i = 0; i < count; i++) {
System.out.println(i + numbers.length - 1);
}
It prints:
5
6
7
Your array has 6 items and is indexed from 0 to 5. When you try to get item that has index >=6 it throws ArrayIndexOutOfBoundsException
Understanding Array IndexOutofbounds Exception in Java , Understanding Array IndexOutofbounds Exception in Java the catch statement, because if we don't handle the exception appropriately, we may conceal it and I've been learning to code recently, but unfortunately iterating through arrays and understanding their Length property and not going out of bounds eludes me. I have the following exercise that I need to solve in Java - input a few numbers, parse them and put them into an array then get the three largest numbers in it and print them in descending order.
If you want to print them in descending order use
System.out.println(numbers[numbers.length - 1 - i])
Accessing array out of bounds in C/C++, What if programmer accidentally accesses any index of array which is out of bound ? C don't provide any specification which deal with problem of accessing (a) the first element of an array is the zeroth (b) the last element of an array is the array size - 1 (c) the position number contained within square brackets is called a subscript (d) a subscript cannot be an expression.

Comments numbers array has indexes ranging from 0 to 5. In the println statement we are adding 5 (which is length of the array - 1) to the 'i' in the first iteration of the loop it gives the last element of the array . during second iteration of the loop 5 is added to i(which is 1 now) equals 6 but there are not enough values in your array to fetch the value. Which gives outofbounds exception. array subscripts start at 0 in Java why do you have a 'count' variable? just print out both i and count as first line of your loop, maybe that 'll help making some things clear As part of learning to code, it would help immensely once you get familiar with the debugger in your favorite IDE @PraneethGudumasu Right, I got it now. I am in essence combining the value of i and the length of the array but the entire thing is actually an Index I want retrieved. So in the first iteration of the loop i = 0 + numbers.length - 3 which is 6 - 3 = 3. The result is 3, as in "Give me what is at index 3", which in my case is the number 4. @Stultuske The original thing had the user input the numbers which I wanted to sort and print the largest three. I forgot to remove the count after hardcoding the input of the array and posting, sorry. Great explanation! When I was first learning my professor taught us about Arrays in the context of Excel spreadsheets. A single Array is a column starting at A[0], going through A[n]... Once he explained it like that to me, it clicked. Maybe that might work for others as well. Since my education started at early age in high school and we used to code on pascal/C I'll always visualize an array as a matrix. And in this case the matrix has only one row...
