To change the position of the scrollbar using CSS, there are various approaches which can be implemented to change scrollbar position and can be placed in any of four directions. In this article we are having div elements with text content inside it. Our task is to change the position of scrollbar in different direction. We will be changing the scrollbar position to right, left, top and bottom. Approaches to Change the Position of the Scrollbar Here is a list of approaches to change the position of the scrollbar using CSS which we will be discussing in this article with ... Read More
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 More
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 More
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 More
When working with dates in Java, it's common to need to increment or decrement months. The Calendar class makes it easy to manipulate dates. This article shows how to decrement the current date by a specified number of months using the Calendar class. Problem Statement Given a Java program to decrement the current date by a specified number of months using the Calendar class. Output Current Date = Thu Nov 22 16:37:42 UTC 2018 Updated Date = Thu Mar 22 16:37:42 UTC 2018 Basic Approach Below are the steps to subtract months from current date using Calendar.add() ...

Octal Number Octal number is also one of the number systems available. The octal number is represented with 8 digits which is from 0 to 7(0, 1, 2, 3... 7). The octal numbers are expressed as base-8 in the numeral system. Hexadecimal Number Hexadecimal number is also one of the number systems available. The hexadecimal number is represented with 16 digits which is from 0 to 15(0, 1, 2, 3... 15). From 10 to 15 it is represented as A to F. The hexadecimal numbers are expressed as base-16 in the numeral system. Problem Statement First convert the octal ... Read More
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 More
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 More
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 More
