Devin AI: World\'s First AI Software Engineer
Devin AI is a fully automated AI software engineer, that has been hyped since the release of its demo. Well there are quite different opinions circulating on the internet regarding whether the demo was faked or will the technology result in the end of career in software engineering. What is Devin AI? Devin is the first AI engineer which is a combination of human expertise and machine learning developed by Cognition Labs. It is not just another AI assistant like Alexa but is designed to be a teammate in coding with capabilities beyond just automation. It is known for its ...
Read MoreJava Program to Calculate Standard Deviation
In this article, we will understand how to calculate standard deviation. The standard deviation is the measure of how spread-out numbers are. The symbol of standard deviation is sigma( σ ). It is the square root of variance. Standard deviation is computed using the formula square root of ∑(Xi - ų)2 / N where Xi is the element of the array, ų is mean of the elements of the array, N is the number of elements, ∑ is the sum of the each element. Problem Statement Given a program in Java to calculate the standard deviation of a given ...
Read MoreJava Program to illustrate Total Marks and Percentage Calculation
We will demonstrate how total marks and percentages are calculated using Java programs. The term total marks refer to the summation of all the available marks, while the term percentage refers to the number obtained by dividing the calculated marks by total marks and multiplying the resultant by 100. percentage_of_marks = (obtained_marks/total_marks) × 100 Problem Statement Given a Java program to calculate the total marks and percentage of a student in a given set of subject. Input marks = { 69, 88, 77, 89, 98, 100, 57, 78 } Output Total Marks is: 656 Total Percentage is: ...
Read MoreJava Program to Find Area of circle Using Method Overloading
We can calculate the area of the circle in Java using Method Overloading. “Method Overloading” is a feature in Java that allows one to write more than one method in the same class using the same method name. It will enable us to declare more than one method with the same names but with different signatures i.e., the number of parameters in the method may be different or the datatype of parameters may be different. Now, let us achieve Method Overloading in Java by considering the “area of a circle” as an example. Before moving to an example, now ...
Read MoreJava program to delete duplicate lines in text file
The interface set does not allow duplicate elements. The add() method of this interface accepts elements and adds to the Set object, if the addition is successful it returns true, if you try to add an existing element using this method, the addition operations fails returning false. Problem Statement Given a file which contains duplicate lines, write a program in Java to read the file, remove duplicate lines, and write the unique lines to a new file. Input Hello how are you Hello how are you welcome to Tutorialspoint Output Hello how are you welcome to Tutorialspoint ...
Read MoreDifference Between Data Analytics and Predictive Analytics
Data analytics is a process which is used to reach the conclusion of the given information. This process is done by filtering the raw data. Predictive analytics is a process in which predictions are made about the results with the help of the current information. In this article, we will discuss the difference between Data and Predictive Analytics. Data Analytics Data analytics is a process in which the raw data is analyzed and conclusions are drawn accordingly. A systemic computational process is needed along with cleaning, aggregation, visualization, and interrogation of the data. The output of the data analytics is ...
Read MoreJava program to check if a string is a valid number
In Java, verifying whether a string is a valid number is a common requirement in various applications. This process ensures that the string can be safely converted to a numerical type without causing runtime exceptions. To validate if a string can be converted to these types, we use the Integer.parseInt() and Float.parseFloat() methods, respectively. Problem Statement Given a string that may contain an integer or a float value, write a Java program to check whether it is valid number or not. Input "100" //string value Output 100 // ...
Read MoreJava Connection setTransactionIsolation() method with example
In a database system, where more than one transaction is being executed simultaneously and in parallel, the property of isolation states that all the transactions will be carried out and executed as if it is the only transaction in the system. No transaction will affect the existence of any other transaction. Transaction Isolation Levels in Java Connection JDBC (Java Database Connectivity) provides support 5 transaction isolation levels through Connection interface. TRANSACTION_NONE: It is represented by integer value 0 does not support transactions. TRANSACTION_READ_COMMITTED: It is represented by integer value 2 supports ...
Read MoreDifference between Frameworks and Programming Languages
Programming languages are used to write code to develop websites and applications. Framework is a platform on which different programming languages can work. Programming languages depend on syntax while frameworks deal with architecture. In this article, we will talk about the difference between Frameworks and Programming Languages. Programming Languages Software developers use different kinds of programming languages to develop an application. They have to use the syntax of a programming language to give instructions. These instructions let the computer know how to execute a code. The processor converts the code into machine language which is understood by computers. The output ...
Read MoreJava Program to Find Common Elements in Two ArrayList
In this article, we will learn how to find common elements in two array-list. The ArrayList class extends AbstractList and implements the List interface. ArrayList supports dynamic arraysthat can grow as needed. Problem Statement In the given array, we aim to find the common elements in two ArrayList objects in Java, array lists are created with an initial size. When this size is exceeded, the collection is automatically enlarged. When objects are removed, the array may be shrunk. Below is a demonstration of the same − Input − First list: [Java, Scala, Shell, JavaScript] Second list: [Java, Python, Shell] Output ...
