Sure, there are a few ways to get the last value of an ArrayList in Java.

Here are two ways to get the last value of an ArrayList:

1. Using the .get() method:

Java

ArrayList<Integer> myList = new ArrayList<>();
myList.add(1);
myList.add(2);
myList.add(3);

// Get the last value of the ArrayList using the .get() method.
int lastValue = myList.get(myList.size() - 1);

In this example, the myList variable is an ArrayList that has the values 1, 2, and 3. The .get() method returns the element at the specified index. The lastValue variable is assigned the value of the last element in the ArrayList, which is 3.

1. Using the .size() and .get() methods:

Java

ArrayList<Integer> myList = new ArrayList<>();
myList.add(1);
myList.add(2);
myList.add(3);

// Get the last value of the ArrayList using the .size() and .get() methods.
int size = myList.size();
int lastValue = myList.get(size - 1);

In this example, the myList variable is an ArrayList that has the values 1, 2, and 3. The .size() method returns the number of elements in the ArrayList. The .get() method returns the element at the specified index. The lastValue variable is assigned the value of the last element in the ArrayList, which is 3.

Which method you use depends on your specific needs. If you need to get the last value and you don't need to do any further processing on the element, then the .get() method is a good option. If you need to do further processing on the element, then the .size() and .get() methods is a good option.
