In this article, we will learn how to sort an ArrayList in ascending order using Java. Sorting allows us to arrange elements in a specific order. We will use the Collections.sort() method, which simplifies sorting, whether you're dealing with integers or strings. The program will demonstrate sorting an ArrayList of numbers and names in ascending order. Problem Statement Write a Java program that sorts an ArrayList of elements in ascending order. We'll look at two examples—one with integer values and another with string values. Input 1 Points[50, 29, 35, 11, 78, 64, 89, 67] Output 1 Points (ascending)[11, 29, 35, ... Read More
In this article, we will understand how to find the area of a trapezium using Java. The trapezium is a type of quadrilateral that has at least one pair of sides parallel to each other. The parallel sides of a trapezium are called bases and the non-parallel sides of a trapezium are called legs. It is also called a trapezoid. The area of a trapezium is calculated using the formula − (height/2 * (side_1 + side_2). i.e. Area = ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sides Below is a demonstration of ...

In this article, you will learn how to check if none of the strings in a list start with a specific letter using Java. This approach is useful for validating or filtering data. We will use the Stream API to evaluate the condition and return a boolean result based on whether any string starts with the given letter. Problem Statement Write a program in Java to check if none of the strings in the list matches the condition. Input pqr, stu, vwx, yza, vwxy Output No match for the starting letter as f? = true Steps to check if none of ... Read More

In this article, we'll explore how to get the first Friday of any given month in Java. The program will use Java's LocalDate class and TemporalAdjusters to automatically calculate the first Friday based on the input date. We will walk through how this works step by step and see how the code performs this task. Problem Statement Write a program in Java to get the first Friday in a month. Below is a demonstration of the same − Input Current date = 2019-04-01 Output Current date = 2019-04-01 First Friday date = 2019-04-05 Steps to get the first Friday in a ... Read More
