In this article, we will sort a long array in Java. We will be using the Arrays.sort() method of Arrays class which is present in java.util package. It will helps us to organize data in ascending order, making it easier to use. We'll start with an unsorted array, display it, sort it using Java’s built-in method, and then display the sorted array. Problem Statement Given an unsorted array of long numbers write a Java program to sort the unsorted array. Input Unsorted long array: 987, 76, 5646, 96, 8768, 8767 Output Sorted long array:7696987564687678768 Steps to sort the long Array Following are ... Read More
In this program, we'll compute the sum of the series 1/1! + 2/2! + 3/3! + ... + n/n! using Java. This involves calculating factorials and summing the results of each term divided by its factorial. We'll use Java's basic arithmetic, loop control, and built-in classes to achieve this.Problem StatementWrite a Java program to calculate the sum of the series 1/1! + 2/2! + 3/3! + ... + n/n! and print the result.Steps to find the sum of a seriesFollowing are the steps to find the sum of a series −Import necessary classes from java.io and java.lang package.Initialize variables for the sum and ...

The cube root of a number is an integer value when multiplied by itself thrice, giving the original number. In this article, we are going to write a Java program to find the cube root of a number using binary search. Finding the cube root of a number is one of the applications of the binary search algorithm. We will discuss in detail how we calculate the cube root using a binary search algorithm in Java. Problem Statement Write a Java program to find the cube root of a number using Binary Search − Input 1 64 Output 1 4 ... Read More
In this problem, we will find two array elements such that the difference between them is maximum using Java. We can make a pair of each element and find the difference between the elements of each pair. After that, we can take a pair whose element has a maximum difference. Another approach is to sort the array and take the largest and smallest elements from the array. Problem statement We have given an array containing the integer values. We need to find two array elements to maximize the difference between them. Input 1 array[] = { 50, 10, 30, ... Read More
In this article, we will learn how to set the horizontal alignment of content in a JTextField class using Java Swing.

When we execute certain SQL queries (SELECT query in general) they return tabular data. The java.sql.ResultSet interface represents such tabular data returned by the SQL statements i.e. the ResultSet object holds the tabular data returned by the methods that execute the statements which requires the database (executeQuery() method of the Statement interface in general). The ResultSet object has a cursor/pointer which points to the current row. Initially, this cursor is positioned before the first row. Java ResultSet isLast() Method The isLast() method of the ResultSet interface is used to determine whether the cursor is on the last row of the ... Read More
