CS46A Fall 18

Write a SimpleLineArrayManager class which manages SimpleLine objects. A SimpleLine represents a line in 2-d space. It is simpler than the one in the graphics library. Copy it into your project. You can look at the documentation for the class by opening the class in the editor window. On the right-hand side where it says "Source Code", click the down arrow and select "Documentation."

The SimpleLineArrayManager has an instance variable SimpleLine[]. Call the instance variable lines. Its constructor takes an array of SimpleLine objects as a parameter

Provide these method

public double sum() gets the sum of length of all the lines in the array. Remember the Pythagorean theorem. I made a private helper method getLength because we need to calculate the length in multiple places and do not want to repeat the work.
public void swap(int index1, int index2) - swaps the element at index1 with the element at index2. If either index is out of bounds, do not changing anything.
public SimpleLine shortest() gets the shortest line. Remember the Pythagorean theorem. I made a private helper method getLength because I needed to calculate the length in two places and did not want to repeat the work. If the array has a length of 0, it is empty so return null
public String toString() gets a string representation of the array - provided. (This is why the instance variable must be called lines.)

Provide Javadoc

For the draft, define the instance variable, implement the constructor and the sum method

9A draft:
9A final:

You are going to to work with a partially filled array in this problem. Write a class to manage an array of Strings. Call the class GrowableArray. GrowableArray constructor takes no parameters but initializes the array so it can hold 8 elements. Use the constant provided, CAPACITY.

Provide methods:

Hint: The algorithms to implement the methods is explained in your text book

public void add(String toAdd) adds the given string at the end of the partially filled array.
public void add(String toAdd, int index) adds the String at the specified index. Grow the array if necessary. Shift the elements with a higher index and then add the element
public void remove(int index) removes the element at the given index by shifting elements at a higher index to the next lower index.
private void growIfNeeded() checks to see if the array is full. If it is, it doubles the size of the array and copies the elements to a the new array in the same order. This is provided for you
public String toString() returns a string representation of the partially filled array. It does not necessarily include all elements. This is provided for yo

Provide Javadoc

For the draft, implement the constructor and the first add method

9B draft:
9B final:

Weather.com maintains a table of the average high temperatures by year for various cities. TemperatureTable manages a 2d array of ints representing these temperatures.

The table for 3 years for San Jose might look like this

	2017	2010	2000
Jan	58	59	40
Feb	62	60	45
Mar	66	65	65
Apr	70	72	68
May	75	73	72
Jun	80	81	83
Jul	83	84	90
Aug	82	82	87
Sept	81	80	81
Oct	74	75	71
Nov	65	66	68
Dec	58	56	59

For the South Pole, since the temperatures do not vary much, they only record 3 values per year

	2017	2000
Nov - Feb	-17	-15
Mar - Jun	-58	-63
Jul - Oct	-65	-80

The constructor that takes two parameters

the name of the city
a 2d array representing the "monthly" temperatures

Provide the constructor and instance variable.

Provide these methods

last() Gets the element in the last column of the last row. Do not use a loop
getName() Gets the name of the city
getHighest() Gets the largest value in the array
public boolean contains(int target) Returns true if the target is in the array, otherwise false

For the draft, provide the constructor, instance variables, and the last() method.
