Java menu driven program to check positive negative or odd even number
A number is said to be a positive number if it is greater than 0 and if it is less than 0 then it is called a negative number. The negative number is followed by a minus sign (-) to identify it as a negative number. A number is said to be an even number if it is divisible by 2 else it is called an odd number. In this article, we will see how to check if a number is positive, negative, or even, odd by using Java programming language. We will be implementing the application using a switch ...
Read MoreJava program to print even length words
In this article, we will understand how to print even-length words. The string is a datatype that contains one or more characters and is enclosed in double quotes (“ ”). Char is a datatype that contains an alphabets an integer or a special character. Problem Statement Write a Java program to print even-length words. Below is a demonstration of the same − Input Input string: Java Programming are cool Output The words with even lengths are: Java cool Approaches to print even length words Below are the different approaches to print even length words − Using ...
Read MorePattern UNIX_LINES field in Java with Examples
This flag enables Unix lines mode. In the Unix lines mode, only '' is used as a line terminator and ‘\r’ is treated as a literal character. Example 1 import java.util.regex.Matcher; import java.util.regex.Pattern; public class LTERAL_Example { public static void main(String[] args) { String input = "This is the first line\r" + "This is the second line\r" + "This is the third line\r"; //Regular expression to accept ...
Read MoreJava program to check for URL in a string
In general, to check if a given string is a valid URL(Uniform Resource Locator), we will create a method that tries to form a URL object and catches any exceptions to determine if the string is a valid URL. By using Java's URL class and exception handling, we will demonstrate a straightforward approach to verify the correctness of URL strings. We can import from java.net package object is created from the input string, then converted to a URI using toURI() method. Problem Statement A program can be created to check if a string is a correct URL or not. An ...
Read MoreJava System.nanoTime() vs System.currentTimeMillis
What are the Time Operations in Java? There are two-time operations provided by the Java environment. For time-related operations, users can use these operations. System.nanoTime() System.currentTimeMillis() System.nanoTime() mainly known as an expensive call, is used to get a more specific value of time. And, System.currentTimeMillis() most authentic possible passed time, helps to get the time value based on the operating system. ...
Read MoreHow to Read a File into an ArrayList in Java?
In Java, an ArrayList is a resizable array, which is implemented as part of the Java Collections Framework. It is a dynamic data structure that can hold any type of objects, including primitive types such as integers and characters. As per the problem statement we have to read a file into an ArrayList. First and foremost we will take the path of the file as input and then we will apply different method to read the file. Let's start!Example For instance Suppose the input file is “myfile.txt”. After reading the content of the file, the result ...
Read MoreJava Program to Segregate 0s on Left Side & 1s on Right Side of the Array
Segregation is a process in the field of software engineering where a code is forced to depend on those methods that are not in use. The segregation interface is known as ISP. It splits the interfaces that are vast in nature. In a Java environment, there are lots of advantages to implementing the segregation principle. It increases the readability of the particular code. It also helps to maintain that particular code conveniently. Problem Statement There is an array of 7s and 16s aimlessly. We must segregate the 7s on the left side and the 16s on the right. The basic ...
Read MoreHow to Check if an Array is Empty or Not in Java
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to check if an array is empty or not. An array is said to be an empty array, if the array has zero element or no element in it. Let’s explore the article to see how it can be done by using Java programming language. InstancesTo show you some instances: Instance-1 Suppose the original array is {1, 3}. After checking if it is empty or not the result will be − Array is ...
Read MoreKotlin vs Java, Which One is the Best?
There is no comparison between Kotlin and Java because one is best than another, so we could not decide which is best. Because Kotlin is a vibrant, advanced software programming language. It is simple to learn, particularly if you are already familiar with Java (it is completely compatible with Java). Kotlin is used to create Android applications, web server applications, and many other things. Java is a well-known software program. It is used to create smartphone applications, web applications, desktop applications, games, and many other things. It depends, as with everything, so we'll take a glance at the main differences ...
Read MoreWhy Java is a Secure Programming Language?
As technology continues to grow and evolve, so does the number of cyber threats. Cybersecurity is now a top priority for many people, businesses, and governments. A secure programming language is a key component of any effective cyber security strategy. Secure Programming is the Key to Data Protection: Why You Need It? A secure programming language is designed to be resistant to attack. It is for preventing malicious code from being executed. It is also to protect data from being stolen. It also provides safeguards to ensure that the code is not easily altered or corrupted. One of the biggest ...
