As a developer, you probably love coding but dread the inevitable merge conflicts that come with Git. These conflicts can disrupt your flow and waste precious time. Fortunately, there's a way to automate the resolution process, ensuring you can keep working smoothly. In this article, I'll show you how to set up automatic conflict resolution in Git, favoring either your changes or those from another branch. My First Encounter with Merge Conflicts I remember my first major merge conflict like it was yesterday. I had just finished a big feature and was excited to merge my branch. Instead of celebrating, ... Read More
The GregorianCalendar class in Java allows us to manipulate dates and times easily. In this example, we will create a GregorianCalendar object and use it to display the current date and the date of the previous month. Problem Statement Write a Java program and create a GregorianCalendar object, display the current date, and then modify this date to show the date of the previous month. Output Current date: Mon Nov 19 18:07:03 UTC 2018 Input Modified date (Previous Month): Fri Oct 19 18:07:03 UTC 2018 Steps to display previous month from GregorianCalendar Below are the steps to display previous ...

In Java, converting integers to different numeral systems can be easily achieved using built-in methods. The Integer.toOctalString(int) method allows you to convert an integer to its octal string representation. This is particularly useful in applications that require data representation in octal format. To convert integer to octal in Java, use the Integer.toOctalString() method. Problem Statement Given a set of integer values, we need to convert each integer to its octal string representation using the Integer.toOctalString(int) method. Input int val = 768; Output Octal String = 1400 Step to convert the integer to octal Below are the steps to convert integer ... Read More
In this section, we are going to write a Java program to find maximum odd number in an Array using Stream and Filter. Odd numbers are the numbers which cannot be divided by 2 or these numbers give remainder as 1 when they are divided by 2. In other terms which can be written in the form of 2n+1. We will find the maximum odd number in the array. Problem Statement Write a program in Java to find maximum odd number in array using stream and filter − Input array = {1, 7, 2, 3, 9, ... Read More
String, the series of characters, used in Java programming enable to save memory consumption and boost the performance. We can save a string to a file using Java program can be initiated in multiple ways and has been introduced in Java version 11. Four parameters can be used to save a string to a file using Java. They are the file path, character sequence, charset, and options. File path and character sequence, these two are the most important and mandatory for this approach to write into a file. This technique encodes the characters as the content, and it returns the ... Read More
An array can be sorted in case-insensitive order using the java.util.Arrays.sort() method. Also the java.text.Collator class is required as Collator.getInstance() is used to obtain the Collator object for the required locale. Problem Statement Write a program in Java to sort an array of strings in a case-insensitive order. A program that demonstrates this is given as follows − Input The unsorted array is: [apple, mango, Banana, Melon, orange] Output The sorted array in case-insensitive order is: [apple, Banana, mango, Melon, orange] Steps to sort an array in case-insensitive order Below are the steps to sort an array in case-insensitive ...

In this article, we will learn how to write an array of strings to a text file using Java. The program demonstrates how to use the FileWriter class to create and write a file. This method helps save data to a text file for future retrieval or processing. FileWriter class: This class extends the OutputStreamWriter class and is used to write streams of characters to a file. It provides methods to write text data easily and efficiently, making it a key tool for handling file output operations in Java. Problem Statement Write a program in Java that writes an array ...

In this article, we will learn how to replace a specific word in a sentence with asterisks using Java. This technique can be useful for obscuring certain words in a text for privacy or censorship purposes. Problem Statement Develop a program in Java that takes a sentence and a word to be censored as input, then outputs the sentence with the specified word replaced by asterisks, while preserving the original format of the sentence. Input This is a sample only, the sky is blue, water is transparent Output This is a ****** only, the sky is blue, water is transparent ... Read More
An array can be reversed in groups of a given size by reversing the subarrays of the required size. In the given article, the program demonstrates a technique for reversing an array in groups of a specified size. This technique is useful in various computational tasks and algorithm design. The program takes an array and a group size as input and reverses the array in groups of that size. The original and modified arrays are then printed to the console. Problem Statement Write a Java program to reverse an array in groups of a given size. An example of ... Read More
This article will explain how to iterate over ArrayList using lambda expression. The ArrayList class is a resizable array that can be found in java.util package. The difference between a built-in array and an ArrayList in Java is that the size of an array cannot be modified. Problem Statement Write a Java program to iterate over an ArrayList using lambda expressions. Below is a demonstration of the same − Input Run the program Output The list is defined as: Java Python Scala Mysql Redshift Approaches to find length of the longest substring without repeating characters ...
