Java 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 ...
Read MoreWhy is Java a Robust Programming Language?
Java is a programming language and it is called by different names for its work. These names are called robust programming, object-oriented programming, secure programming languages, etc. But here we discuss Java as a robust programming language. Java is a robust programming language that can manage run-time errors because it checks the programming code through in run-time and compile time. If a Java virtual machine (JVM) detects a runtime error, it does not report it to the underlying platform. Rather, it will suspend or terminate the program and prevent this from causing any damage to the system. Therefore, we are ...
Read MoreWhere is Java Used in the Real World?
Java is a programming language that has been used in the real world, it works for commercial websites, financial applications, android applications, scientific applications, and much more. Here, in this post, we will focus on where Java programming language is used the most. Let’s have a look at the below 8 points. 1. Android Apps Android apps are a good place to start if you want to see where Java is used. If you open any app on your Android phone, it is actually written in Java and uses Google's Android API, which is similar to JDK. As a result ...
Read MoreWhat is advanced Java?
Introduction to Advanced Java Core Java (J2SE) and Advanced Java are the two components that make up the Java programming language (JEE). The foundations of the Java programming language, including its data types, functions, operators, loops, threads, and exception handling, are discussed in the "core Java" section of this book. It is used in the process of developing apps for widespread usage. Whereas Intermediate Java focuses on more advanced topics, such as database connection, networking, Servlet, web services, and so on, Advanced Java addresses more fundamental ideas. In this article, we will talk about what advanced Java is, and the concepts ...
Read MoreJava program to find whether the given character is an alphabet or not
For a character "ch", write a Java program to verify whether it lies between a and z (both small and capital). If it does it is an alphabet otherwise, not. Alphabets are the set of letters written to represent particular sounds in a spoken language like English. Example Scenario 1: Input: character = 'e'; Output: Yes given character is an alphabet Example Scenario 2: Input: character = '4'; Output: No given character is not an alphabet Using ASCII Values The term ASCII stands for American Standard Code for Information Interchange. Every English letters has an ASCII value ...

Read MoreJava Connection getMetaData() method with example
Generally, Data about data is known as metadata. The DatabaseMetaData interface provides methods to get information about the database you have connected with like, database name, database driver version, maximum column length, etc... The getMetaData() method of the Connection interface retrieves and returns the DatabaseMetaData object. This contains information about the database you have connected to. You can get information about the database such as the name of the database, version, driver name, user name, URL, etc… by invoking the methods of the DatabaseMetaData interface using the obtained object. This method returns the DatabaseMetaData object which holds information about the underlying ...
