- Lab 02: Splitting a URL into pieces URLS are composed of five pieces: The scheme, also known as the protocol The authority (may further be divided into the user info, the host, and the port) The path The fragment identifier, also known as the section or ref The query string Read-only access to these parts of a URL is provided by nine public methods: getFile(), getHost(), getPort(), getProtocol(), getRef(), getQuery(), getPath(), getUserinfo(), and getAuthority(). Write a Java program which uses these methods to split URLS entered on the command line into their component parts.Failures to assert Launch the DebuggerThe Issue: A failed assert often produces a message and terminates the application. This is not very helpful for locating issues. It would be more preferable if a failing assert could launch the debugger.LabProgram.java:8: error: class HorseDatabase is public, should be declared in a file named HorseDatabase.java public class HorseDatabase { ^ 1 error Complete the Java program to create a Horse table, insert one row, and display the row.

- Computer Science The goal of this assignment is to create an app that can capture, tag, save, and retrieve photos on your smartphone.Capture: When clicked, it takes a picture and shows a thumbnail image. Tag: A user can type multiple tags (separated by a “;”). Save: When clicked, it saves the photo in a database along with the tags. Load: A user can specify one or more tags. Your app will find and show the first photo that had any of those tags. When there are multiple photos matching the criteria, the App should have an UI element to show them one by one, e.g., when the user slides a slider.(1) Complete two files to submit.
