In this post, we will look at the addAll() method of the ArrayList class in detail. There are two overloaded implementations of the addAll() method. public boolean addAll(Collection c) public boolean addAll(int index, Collection c) Let’s look at the above methods one by one. public boolean addAll(Collection c) Method declaration – public boolean addAll(Collection c) […]

add() method is used to add the elements into the ArrayList. There are two overloaded implementations of the add method for the ArrayList class. public boolean add(E e) public void add(int index, E element) Let’s look at the overloaded methods one by one public boolean add(E e) Method declaration – public boolean add(E e) What

ArrayList is a resizeable array implementation of the List interface. It implements all of the list operations and provides methods to manipulate the size of an array that is used internally to store the elements. ArrayList class is equivalent to the Vector class, except that it is unsynchronized. We can think of ArrayList as a
The isEmpty() method helps us in finding out whether a vector is empty or not. In this post, we are going to discuss the isEmpty() method of the vector class in detail. Method declaration – public synchronized boolean isEmpty() What does it do? – It tells us whether the vector is empty or not by

trimToSize() method is used to trim the capacity of the vector to its current size. It can be used to minimize the storage of the vector but it can also increase the amount of incremental reallocation and hence can decrease the performance. Method declaration – public synchronized void trimToSize() What does it do? – It

A variadic function is a function that accepts a varying number of arguments. To make the function variadic, we have to use an ellipsis ( … ) before the type of the last function parameter in the function declaration. Syntax The last parameter of the variadic function receives the variadic arguments as a slice, which

We have already sorted an array in one of our previous articles and in this post, we are going to sort the slice using some inbuilt functions provided by the Go language. We will be looking at the below points in this post. How to sort a slice of integers in ascending order Sorting a

Earlier, we have seen how to execute all the test cases within the package or run a specific class using the testng.xml file ( Article link ). But sometimes, we might be selective while executing test cases. So, this post will focus on these scenarios where we need to include or exclude tests based on

In this post, we are going to look at the clear() method of the Vector class in detail. Method declaration – public void clear() What does it do? – It will remove all of the elements present in the Vector at that time and thus will empty the vector What does it return? – This

In this post, we are going to learn about the Golang slices in detail. Previously we have learned all about the arrays in the Go language but there is one major limitation to the arrays, they cannot grow or shrink in size as per our needs. To overcome this limitation of the arrays, Go provides
