java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

This exception is thrown when a program attempts to access an element at an index that is out of bounds of the specified data structure. In this specific case, the program is trying to access the element at index 0 of a data structure, but the size of the data structure is 0, which means there are no elements in the data structure to access.

For example, if you have an empty ArrayList and you try to access the first element using the get() method, you will get this exception because there are no elements in the list to retrieve.

To resolve this exception, you need to check the size of the data structure before trying to access any element at a specific index. You can use an if statement to check if the size is greater than the index you are trying to access, and then perform the necessary action. Alternatively, you can try to add elements to the data structure before accessing them to ensure that the size is not 0.
