Program Plan Intro
String class:
- The “String” class provides a number of methods that examines for a string inside of a string.
- The term “substring” refers to a string that denotes another string’s part.
- The “startsWith” method would determine whether calling string of object begins with a specific substring.
- The method returns “true” if string begins with specified substring, it returns “false” otherwise.
- The “endsWith” method would determine whether calling string would end with a specified substring.
- The method returns “true” if string ends with specified substring, it returns “false” otherwise.
- The “regionMatches” method would determine whether specified regions for two strings match.
- The first argument of this method can be “true” or “false” that indicates whether a case-insensitive comparison could be performed.

What is a HashMap? What is its purpose and how do you use it? Answer these questions in writing, and use the Java library documentation of Map and HashMap for your responses. Note that you will find it hard to understand everything, as the documentation for these classes is not very good. We will discuss the details later in this chapter, but see what you can find out on your own before reading on.

- Create a class MapTester (either in your current project or in a new project). In it, use a HashMap to implement a contacts list similar to the one in the example above. (Remember that you must import java.util.HashMap.) In this class, implement two methods: public void enterNumber(String name, String number) and public String lookupNumber(String name) The methods should use the put and get methods of the HashMap class to implement their functionality.arrow_forwardWhere in the link library can I find the method that will produce a random number between the specified values?arrow_forwardFor this lab, you will need to use the files BagInterface.java, Item.java, and LinkedBag.java.arrow_forward
