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. StringBuilder class: The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed. It provides several methods that “String” class does not have. The “append” method accepts an argument that might be a primitive data type. It appends a string representation to contents of calling object. The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted. The “replace” method replaces the occurrences of one character with another character. The “toString” method converts a “StringBuilder” object in to a regular string. Given code: String city = “Asheville”; Explanation: The given code stores a string value to a variable that denotes a “String” object.

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.

StringBuilder class:

The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed.

It provides several methods that “String” class does not have.

The “append” method accepts an argument that might be a primitive data type.

It appends a string representation to contents of calling object.

The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted.

The “replace” method replaces the occurrences of one character with another character.

The “toString” method converts a “StringBuilder” object in to a regular string.

Given code:

String city = “Asheville”;

Explanation:

The given code stores a string value to a variable that denotes a “String” object.

Level-0 Diagram for this: A customer sends in an order form containing details of their order and their membership number. A check is made to verify that they are a member. When their order is verified, a check is made to validate that the items ordered are produced by the company. Next, the valid order is used to update the daily order file, and then used to create a shipping list and invoice, which are sent on to the Order Fulfilment System.

In this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like. The program must include a minimum of: 5 circles 5 polygons 5 line commands 2 for loops 1 global variable You may wish to use the standard code for simplegui graphics below: import simplegui def draw_handler(canvas): frame = simplegui.create_frame('Testing', 600, 600) frame.set_canvas_background("Black") frame.set_draw_handler(draw_handler) frame.start() Submit Your Code After you write your code here in the programming environment, you will check it and submit it as usual. However, the grader will only perform basic checks against some requirements. If your code passes, you should submit your work, and your teacher will manually grade your submitted work using a rubric.
