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:

* 
* * 
* * * 
* * * * 
* * * * * 

You need to write a Java program to print the above pyramid pattern. How many levels the pyramid triangle would have will be decided by the user input. You can print this kind of pattern by using print() and println() method from System.out object. System.out.print() just prints the String or character you passed to it, without adding a new line, useful to print stars in the same line. 

How to Print Prime Numbers from 1 to 100 in Java [Solved]

Hello guys, today, I'll share with you a simple problem of writing a Java program to print prime numbers up to a given number like saying prime numbers from 1 to 100. It's one of the most common coding exercises for programmers learning in Java, as it gives you an opportunity to learn more about the essential operators in Java Programming. The key here is that you cannot use a library function which can simplify your job, you need to devise the algorithm for checking prime number by yourself. One of the most popular algorithms for generating prime is Sieve of Eratosthenes,  which we have discussed earlier, but in this post, we will take a simpler approach.

How to count a number of words in given String in Java? [Solved]

Can you write a method in Java that accepts a String argument and returns a number of words in it? A word is a sequence of one or more non-space characters i.e. any character other than '' (empty String). This should be your method signature:

public int count(String word);

This method should return 1 if the input is "Java" and return 3 if the input is "Java, C++, Python". Similarly a call to wordCount("    ") should return 0.

3 ways to Find Duplicate Elements in a given Array in Java [Solved]

Hello guys, if you are wondering how to find duplicates from a given array in Java then you have come to the right place. This is one of the most popular coding problems from interviews and there are multiple ways to solve this problem. In this article, I will show you three ways to solve this problem. First, you will learn how to solve the problem using brute force way and then you will see how you can optimize and simplify the solution by using additional memory and using an appropriate data structure like a HashSet or Hash table. In the real interview, you may need to solve this problem in some constraints like you cannot use additional memory or additional data structure that's where knowing multiple ways to find duplicate in Java array really help.

How to Perform Union of Two Linked Lists Using Priority Queue in Java? Example Tutorial

Firstly, The Linked list shall be introduced, then how priority queue in java is been used, Then after that, we shall carry on on the main task.  What is LinkedList? A linked list is a data structure in which each node(element) holds the reference to the next node. You don’t need to go through the struggle of searching the exact node in the link list, all you have to do is go through the previous node because it holds the reference to the next node, then you can easily access it.

3 ways to Count words in Java String - Google Interview Questions with Solution

Today, I am going to share with you Java interview questions from Google, which were asked to one of my readers during the telephonic round. How do you count the number of words in a given String in Java? You can count words in Java String by using the split() method of String. A word is nothing but a non-space character in String, which is separated by one or multiple spaces. By using a regular expression to find spaces and split on them will give you an array of all words in a given String. This was the easy way to solve this problem as shown here, but if you have been asked to write a program to count a number of words in a given String in Java without using any of String utility methods like String.split() or StringTokenizer then it's a little bit challenging for a beginner programmer.

Top 6 Courses to Learn Time Series Analysis in 2025

Time Series is a mathematical concept that consists of data points indexed according to a timed order. A Time-Series can also be defined as a sequence of events taken at successive equally spaced points in time. In Time Series Analysis, we analyze a sequence of data points collected over an interval of time. You should be able to record data points at consistent intervals over a set period. This is different from just recording data points at random intervals. A Time Series Analysis can show how different variables change over time. It provides an additional source of information and a set order of dependencies between the data. Time Series data can also be used for forecasting and predicting future data based on historical data.

3 ways to check if a String contains SubString in Java? IndexOf, contains, and lastIndexOf Example

You have given a String and a subString or a character and you need to find out whether given String contains the given character or substring, how would you do that? Well, there are three main ways to search String in Java, the contains() method, the indexOf() method and the lastIndexOf() method, all from java.lang.String class. First method, contains() accepts a CharSequence, superclass of String and return true if that CharSequence appear on the String you have called. The indexOf() and lastIndexOf() are similar method and both return the index (zero based) from where the given subString or character appear in the String you have called. Only difference between indexOf() and lastIndexOf() is that if given substring appear multiple time then they will return difference index, otherwise both will return the same index. Similarly if given sub-string is not present in the String, both will return -1 and contains() will return false.

How to make Immutable class in Java? Mutable vs Immutable Objects

How I make immutable objects in Java? I've always thought that all objects are immutable, because if you change the content of an String example, it will always create you an new String object and point to that. However later I found that String is a special class and its specially designed as an Immutable class because its often cached. Obviously you cannot cache anything which is not constant and that make sense why String is Immutable in Java. But this encouraged me to learn more about Mutable and Immutable class in Java and how to create a custom Immutable class in Java.

Difference between StringTokenizer and Split method in Java? Example

There are multiple ways to split a String in Java, but two of the most common ways are by using StringTokenizer and the split method of String class. You can use either one of them, but when to use which one? This short article will give you some details about StringTokenizer and Split method in Java to decide which one to use.

1) The StringTokenizer is legacy, Prefer split() as more chances of its performance getting improved as happens in Java 7.

2) The StringTokenizer doesn't support regular expression, while spilt() does. However, you need to be careful, because every time you call split, it creates a new Pattern object and compiles expression into a pattern. This means if you are using the same pattern with different input, then consider using Pattern.split() method, because compiling a pattern takes more time later to check whether a given string matches a pattern or not.
