It's also one of the popular coding questions, so you will also learn how to take a requirement, how to fill gaps in the requirement by asking the right question. A String is nothing but a sentence, which may contain multiple works, or just contain a single word or it may be empty. Your program must produce a String that contains the word in reverse order, for example, if the given input is "Java is Great" then your program should return "Great is Java".
[Solved] How to remove duplicate elements from Array in Java? Example
This is one of the common technical interview questions which are asked to entry-level programmers and software engineers. There are also a lot of variants of how do you remove duplicates from an array in Java, like sometimes the array is sorted, and other times it's not sorted or unsorted. Sometimes, the Interviewer just spends more than half of the interview on this question by progressively making it more difficult by imposing new constraints like removing duplicate elements in place or without using any additional data structure, etc.

How to swap two Integers without using a temporary variable in Java? [Solution]
One of the oldest trick questions from a programming interview is, How do you swap two integers without using a temp variable? This was first asked to me on a C/C++ interview and then several times on various Java interviews. The beauty of this question lies both in the trick to thinking about how you can swap two numbers without the third variable, but also problems associated with each approach. If a programmer can think about integer overflow and consider that in its solution then it creates a very good impression in the eye of interviewers.
How to Print Floyd's Triangle in Java - Example Tutorial
Hello guys, In the last article, I have taught you how to print Pascal's triangle and in today's article, I'll teach you how to print Floyd's triangle in the Java program.

We will create a class to represent matrix and then define a multiplication method to multiply two matrices in Java. I first learned about matrix in class 12th and I first wrote the program to multiply two matrices on my first semester of engineering, so, when I thought about this program, It brings a lot of memories from the past.
How to check is given String is a Palindrome in Java using Recursion
In this tutorial, you will learn how to check if a string is a palindrome in Java using Recursion. A String is nothing but a collection of characters like "Java," and String literals are encoded in double-quotes in Java. A String is said to be a palindrome if the reverse of String is equal to itself like "aba" is a palindrome because the opposite of "aba" is also "aba", but "abc" is not a palindrome because the reverse of "abc" is "cba" which is not equal. Recursion means solving a problem by writing a function which calls itself. In order to check if String is a palindrome in Java, we need a function that can reverse the String.
How to Reverse String in Java with or without StringBuffer Example
Reverse String in Java
There are many ways to reverse a given String in Java. For example, you can use rich Java API to quickly reverse the contents of any String object. Java library provides StringBuffer and StringBuilder class with the reverse() method which can be used to reverse String in Java. Since converting between String and StringBuffer or StringBuilder is very easy it's the easiest way available to reverse String in Java. But, in a coding interview, you may not be allowed to use the JDK API methods to solve this problem. That's why, writing a Java program to reverse String in Java without StringBuffer is one of the popular Java String interview questions, which requires you to reverse String by applying logic and by not using API methods.
How to Remove all adjacent duplicates characters from String in java? Example Tutorial

duplicates from a given String in Java then you have come to the right place. In
the last article, we have seen
how to find duplicate characters
as well as
how to remove duplicate characters from String in Java, and in this article, we will take that topic to another level and remove
adjacent duplicates from given String. This topic gives another perspective to
removing duplicates in a word or phrase. Probably before now, you are familiar
with removing duplicates from a word or phrase, or number. But this topic gives
a detailed understanding of how to remove adjacent duplicates.
How to Perform Binary Tree InOrder traversal in Java using Recursion? Example Tutorial
The InOrder traversal is one of the three popular ways to traverse a binary tree data structure, the other two being the preOrder and postOrder. During the in-order traversal algorithm, the left subtree is explored first, followed by root, and finally nodes on the right subtree. You start traversal from root then go to the left node, then again go to the left node until you reach a leaf node. At that point in time, you print the value of the node or mark it visited and move to the right subtree. Continuing the same algorithm until all nodes of the binary tree are visited. The InOrder traversal is also known as the left-node-right or left-root-right traversal or LNR traversal algorithm.
How to Find Square Root of a Number in Java [Solved] - Example Tutorial
Java program for a square root or a number in Java
How to write a Java program to find the square root of a number is a common Java programming exercise that many institutes use in their Java course along with Java program to print Fibonacci series and How to find Armstrong numbers in Java, which we have seen earlier.

In the first part, I have shown how to traverse a binary tree with a pre-order traversal algorithm using Recursion, and in this article, you will learn how to implement pre-order traversal without using Recursion. You might be thinking that why do you need to learn the iterative solution if a recursive solution is possible and easy to write? Well, this type of question is mostly asked in Programming Job interviews and Interviewers like to see how comfortable a candidate is with both Recursion as well as using other data structures and iteration.
[Solved] 3 Examples to reverse an Array in Java - Example Tutorial
Hello guys, today we are going to see another common coding question from interviews - how do you reverse an array in Java? This is a popular array-based coding problem and often asked programmers during the first few rounds of interviews to check if they can code or not. Well, there are multiple ways to solve this problem and we will see three common ways to ever an array in Java. This method applies to all kinds of arrays like string array or integer array or even with arrays of objects because it's not focused on data types. The first way to reverse an array is by reversing it in a brute force way, without using any additional data structure or library method.
How to Find Even and Odd Number in Java - Program Tutorial Example
Even and Odd number check Java Example
There are many ways to find if a number is even or odd in Java but before moving into technical details on finding even and odd numbers in Java let's what is even and odd numbers in terms of Mathematics. Any number which is completely divisible by 2 is called an even number while a number that is not completely divisible by 2 is called an odd number. If you think in terms of remainder then in the case of even number, the remainder is zero while in the case of odd number remainder will be 1. zero is considered as an even number in maths.
How to Count number of 1s (Set Bits) in a binary number in Java [Solved]
Good morning folks, In today's article, we are going to discuss one of the frequently asked bit manipulation-based interview questions, how do you count the number of set bits in a given bit sequence? Bit Manipulation is an important topic in programming interviews and a good programmer should have sufficient knowledge and skill to work with binary numbers. This kind of question tests the skill of the programmer. Sometimes, it is also asked as to how to count the number of 1s (ones) in a given number? Both are the same question because 1 is also known as set bit. For example, if the given input is 1000110010 then your program should return 4, as three are only four set bits in this bit sequence.
How to Print Pyramid Pattern in Java? Program Example
Pattern based exercises are a good way to learn nested loops in Java. There are many pattern based exercises and one of them is printing Pyramid structure as shown below:
