Java Array Programming Projects Student Labs

String Array Project

the StringArr class as follows

• The Constructors
  • Default Construct should initialize the sArr instance variable to
  3 different strings (of your choosing)
  • Write a constructor with a single parameter, an array of strings, and initialize sArr to the parameter
• Methods
  • Implement all methods described in the source code

Projects :

SeatingChart This classs should have the following:

instance variables: String[][] theChart , int numRows, int numCols .

a default constructor that initializes the instance variables.

the array should be initialized to have empty Strings

A constructor that initializes theChart to the parameter

• Mutator methods:
• public void clearAllSeats(); //this should set all elements in the double array to empty strings
• public void setSeat(int row ,int col, String to); //Sets the value of the seat at row r, column col to String to.
• public void swap(int row1,int col1, int row2, int col2) ;;//Swaps String at row1,col1 with String at row2,col2

• Accessor methods:
• public boolean contains(String str); //returns true if str is in the array
• public int[] getCell(String str);//returns a two element arrow indicating the row and column of str. If str is not in array return an empty array.
• public boolean swap(String s1,String s2) ;;//Swaps s1 with s2. Use row major form to find the first occurance of each STring. Returns false if either element is nonexistant in theChart.
• public int getRow(String str) ;//returns the row number of str; returns -1 if Str is not in array
• public int getCol(String str)//returns the column number of str; returns -1 if Str is not in array
• public String get(int row ,int col); //returns the String at row, col.

MazeGenerator: Create a MazeGenerator Class that creates Maze objects

the Maze class should be implemented using a two dimensional array and should use an X to symbolize a wall and a minus sign to symbolize a clear passage. Below is an example of what a maze object would like, graphically. Every maze should have a starting and ending point (feel free to implement starting and ending points any way that you want-- I used a red S and a red F to symbolize start and finish)

S	-	x	-	-
-	x	-	x	x
-	x	-	x	-
-	x	-	x	-
-	-	-	-	F
