Java Tutorial

In this tutorial, we are going to learn and understand the binarySearch method from the Arrays class in Java. The thing is that the Arrays class has some very useful methods related to arrays, for doing different things, and the binarySearch method is one such method. This is related to the binary search algorithm, and […]

Comparing Arrays in Java Now let’s move on to the next method, with which, we can check whether the two arrays are equally based on their contents. Well, earlier, we had done a program, in which we had created two arrays, with the same contents, and I had asked whether these reference variables are pointing

Sorting The Array (Sort Method) Well, as the name of the method says, it is going to sort our array in ascending order. So, whenever we need our array sorted, we can make use of this Array Sort Java Method. Let’s have a look at a sample program – import java.util.Arrays;public class ArrayBasic {public static

Printing the string representation of the array | Arrays toString JAVA Well, from the name of this method, we can understand that this method converts our given array into a string. This method returns the string representation of the contents in the array, as a list of array elements enclosed in square brackets. Also, the

Some methods from Arrays class Now, let’s have a talk about some methods from the Arrays class too since we have discussed quite arrays. Let’s discuss some static methods from the Arrays class that would help us in many ways, like sorting the array, searching through the array, filling the array with some particular value,

Enhanced for Loop Java In the traditional for loop, we created an iteration variable to iterate through the loop. This means that we are iterating index-wise in the array. Instead of that, we can also directly access the element itself. So, we create a variable that is of the same base type as the array.

Accessing Array Elements In JAVA Now the thing is that we have been accessing the individual elements from the array, but we are doing it manually. Is there something that is better than this? Well, we can make use of for loop to iterate through the individual elements in the array. There is one more

How To Declare An Array In JAVA Well, in order to use an array for storing data of similar data types, we need to first declare/create an array. This is a pretty much easy task, and you will surely understand it and get used to it in no time. This is similar to how we

Arrays in Java We had earlier learned about storing data into some variable.  Every time we need to store some data, we were creating some variables. Let’s consider an example – we need to store the names of some companies. One way to do this is to create a lot of variables to store the

StringBuilder Class in Java We have studied many things about the concept of String. We have also seen that the strings are immutable and studied why are they immutable. Sometimes, using string is great, since it does not allow us to make changes to the object once it is created. But what if we need
