The program also ensures that only columns, and not rows, can be selected. Steps to select a column in JTableFollowing are the steps to select a column in JTable −First we will import the classes from the javax.swing and java.awt package.Set up ... Read More

In this article, we will learn how to format strings into a table using Java. Java's System.out.format() method is a convenient way to display formatted output. We will define a string format that specifies column widths to ensure uniform spacing, allowing us to create a neat table layout. By using this approach, we can display multiple rows of string data in a structured and readable format without manually adjusting spaces for each entry. Steps to format strings into a table Following are the steps to format strings into a table − Define a format string ... Read More
In this article, we will learn to measure the time taken to sort an array in Java. We will look at two methods to calculate sorting time: using the Date class and the System.nanoTime() method. First, we will use the Date class to track the time before and after the sorting operation, allowing us to calculate the duration in milliseconds. Then, we'll utilize System.nanoTime() to capture the time with greater precision, measuring in nanoseconds and converting the result to milliseconds. Different approaches Below are the different approaches to measure the time taken to sort an array using Java− ... Read More
Stacks in Java A stack is a Last-In-First-Out (LIFO) data structure. As shown below, the last book inserted onto the stack is the first to be removed, and the first book inserted into the stack is the last to be removed. In Java, a stack of integers can be created by importing the java.util.Stack package and invoking the Stack() constructor. Integer objects can be pushed onto the stack using the push() method. An example is provided in the following code snippet. Example Following is an example program − import java.util.Stack; public class Testing { public static ... Read More
In this article, we will learn to generate all possible words from a string of phone digits using Java. Each digit on a mobile keypad corresponds to a set of letters, and our task is to find every possible combination of letters that can be formed by pressing those digits. For instance, if the input is "23, " the output would include combinations like "ad, " "ae, " "af, " and so on. We will implement a recursive approach to achieve this, allowing us to systematically generate and print all possible words corresponding to the given digits. Problem Statement Write ... Read More
