Here, we will demonstrate the usage of static inner class using the Java program. Before diving deep into the topic, let us get acquainted with the term Static Inner Class . Static Inner Class An inner class is the one, which is defined within another class. A Static Inner Class is a nested class that is a static member of the outer class. Other static members can be used to access it without first instantiating the outer class. A static nested class lacks access to the instance variables and methods of the outer class, much like static member’s java. Example ... 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

Here, the usage of Hexadecimal shall be demonstrated through the Java Program. Let us get acquainted with the term Hexadecimal before seeing a Java program.
