Error message
java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 3
What broke
The code attempted to access the 6th element of an array that only has 3 elements. This caused an ArrayIndexOutOfBoundsException.
Why it broke
In Java, array indices start at 0, so an array of length 3 has valid indices 0, 1, and 2. Attempting to access index 5 exceeds the bounds of the array.
How to fix
Check the array's length before accessing its elements. Ensure that any index used is within the valid range of 0 to length-1.
Code fix
if (index >= 0 && index < array.length) { value = array[index]; }Explained by ErrorOracle
Prevention tip
Ensure that any index used is within the valid range of 0 to length-1.
