The JavaScript Array splice function is used to add or remove elements from an array. It takes three parameters: the starting index, the number of elements to remove, and any elements to add. If only the starting index is provided, all elements from that index to the end of the array are removed. If the number of elements to remove is not specified, all elements from the starting index to the end of the array are removed. If elements are added, they are inserted at the starting index and any existing elements are shifted to make room. The splice function modifies the original array and returns an array of the removed elements. Keep reading below to learn how to Javascript Array splice in Java.

Javascript Array splice in Java With Example Code
JavaScript Array splice is a method that allows you to add or remove elements from an array. In Java, you can use the ArrayList class to achieve the same functionality. The ArrayList class provides a method called `removeRange()` that can be used to remove a range of elements from the list.
To use the `removeRange()` method, you need to create an instance of the ArrayList class and add some elements to it. Here’s an example:
ArrayList<String> list = new ArrayList<>();
list.add("apple");
list.add("banana");
list.add("orange");
list.add("grape");
In this example, we have created an ArrayList of Strings and added four elements to it. Now, let’s say we want to remove the second and third elements from the list. We can do this using the `removeRange()` method as follows:
list.removeRange(1, 3);
The `removeRange()` method takes two arguments – the starting index (inclusive) and the ending index (exclusive) of the range of elements to be removed. In this case, we are removing elements at index 1 and 2 (i.e., “banana” and “orange”).
After executing the above code, the ArrayList will contain only two elements – “apple” and “grape”.
Similarly, you can use the `add()` method of the ArrayList class to add elements at a specific index. Here’s an example:
list.add(1, "kiwi");
This will add the element “kiwi” at index 1 of the ArrayList, shifting all the elements after it to the right.
In conclusion, the ArrayList class in Java provides methods that can be used to achieve the same functionality as the JavaScript Array splice method.
Equivalent of Javascript Array splice in Java
In conclusion, the Java programming language provides a powerful and efficient way to manipulate arrays using the equivalent of the JavaScript Array splice function. The Java ArrayList class offers a wide range of methods that allow developers to add, remove, and modify elements in an array with ease. By using the ArrayList class, developers can take advantage of the many benefits of Java, including its strong typing system, object-oriented programming features, and robust error handling capabilities. Whether you are a seasoned Java developer or just starting out, the ArrayList class is an essential tool for working with arrays in Java. So, if you’re looking to take your Java programming skills to the next level, be sure to explore the many possibilities of the ArrayList class and its equivalent of the JavaScript Array splice function.
