Scanner class in Java is that class which reads input at runtime given by the tester/user for any primitive datatype. So here, we make use of the scanner class to first read an integer number which is considered as the size of array (total number of data values) followed by which we...

For example, if an array is{2, 2, 3, 4, 3, 4, 2}then the frequency of element “2” is 3, frequency of element “3” is 2 and frequency of element “4” is 2. Java Program to find the frequency of each element in the array In the following example, we have an arraynumbers...
So,when we push an element into the stack, the top pointer first increments its valueand brings it to the position where the upcoming element (i.e. upcoming top) would be inserted.Then, at that positionin the array or the list,we insert the element.This is shown both diagramatically and...

Before implementing Java program for bubble sort let's first see how bubble sort functions to sort array elements in either ascending or descending order. Bubble sort is the simplest sorting algorithm among available ones. However, its simplicity does not carry much value because it is one of ...
