Iterating through Collections Earlier in this chapter, when working with Exercise 01, Creating the AnalyzeInput Application we stopped when we were about to make searches through the data. We made it to the point where we had to iterate through the data and look for characteristics such as wor...

Bubble Sort is a rather simple comparison-based sorting algorithm which works by repeatedly iterating through an array. It compares adjacent elements and swaps them if they are in the wrong order. During each pass, the largest element "bubbles" to its correct position at the end of the array...
Let's go through the following code step-by-step: We are fetching all aforementioned <li> tags with the class cl-static-search-result and iterating through them For each htmlItem, we are going to look for the product details, under an <a> tag for the product title, under a <div> ...

String joined = elements.stream() .map(Object::toString) .collect(Collectors.joining(", ")); Or perhaps sum the salaries of all employees: int total = employees.stream() .collect(Collectors.summingInt(Employee::getSalary))); These are but a few examples of what you can do with streams an...
But when will we need this comparison in practice? Let’s talk about that through examples. 4. Finding theenumInstance by Its Name and Property A common use case that needs the comparison would bedetermining anenuminstance by a givenString. For example, we want to find theWeekday.Satconstan...
