Function<String, String> fun = (String fullName) -> fullName.split("\s")[1]; We create aFunctionwhich is a key extractor. It extracts the surnmaes from the strings. names.sort(Comparator.comparing(fun).reversed(
A student's record consists of his or her distinct ID (a 6-digit number), name (a string with no more than 8 characters without space), and grade (an integer between 0 and 100, inclusive). Output Specification: For each test case, output the sorting result in N lines. That is, if...

Excel can sort records according to any column. Now you are supposed to imitate this function. Input Specification: Each input file contains one test case. For each case, the first line contains two integers N (≤105) and C, where N is the number of records and C is the column that ...

While Bubble Sort is straightforward to understand and implement, its quadratic time complexity makes it less efficient for large datasets compared to the more advanced sorting algorithm. In Java, Bubble Sort can be implemented using nested loops to compare adjacent elements and swap them if ...
Java的Arrays类中有一个sort()方法,该方法是Arrays类的静态方法,在需要对数组进行排序时,非常的好用。但是sort()的参数有好几种,下面我就为大家一一介绍,这几种形式的用法。1、Arrays.sort(int[] a)这种形式是对一个数组的所有元素进行排序,并且是按从小到大的顺序。举例如下:importjava.util.Arrays; public ...
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 ...
