Java Date and Time

The Calendar class is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the calendar fields, such as getting the date of the next week. You are given a date. You just need to write the method, getday , which returns the day on that date. To simplify your task, we have provided a portion of the code in the editor. For example, if you are given the dat

Java Strings Introduction

This exercise is to test your understanding of Java Strings. A sample String declaration: String myString = "Hello World!" The elements of a String are called characters. The number of characters in a String is called the length, and it can be retrieved with the String.length() method. Given two strings of lowercase English letters, A and B, perform the following operations: 1.Sum the lengths of A and B. 2.Determine if is lexicographically A larger than B(i.e.: does B come before A

Java Substring

Given a string, s, and two indices, start and end, print a substring consisting of all characters in the inclusive range from start to end-1. You'll find the String class' substring method helpful in completing this challenge. Input Format The first line contains a single string denoting s. The second line contains two space-separated integers denoting the respective values of start and end. Constraints 1<=|s|<=100 0<=start<end<=n String s consists of English alphabetic letters

Java Substring Comparisons

We define the following terms: Lexicographical Order, also known as alphabetic or dictionary order, orders characters as follows: A<B<...<Y<Z<a<b<...<y<z For example, ball < cat, dog < dorm, Happy < happy, Zoo < ball. A substring of a string is a contiguous block of characters in the string. For example, the substrings of abc are a, b, c, ab, bc, and abc. Given a string, s, and an integer, k, complete the function so that it finds the lexicographically smallest and largest sub
