1. (TCOs 1-8) NOTE: YOU DO NOT have to compile/run this code in eclipse. You are writing the code here only.

Write a class called point

that has attributes and methods to model an (x,y) coordinate in a 2-D environment.

Select appropriate variable(s).

Write a default and parameterized constructor.

Write set and get methods for the variables.

Write a Print method to display the variables when called.

Write a test program to test the methods.

2. (TCOs 1-8) NOTE: YOU DO NOT have to compile/run this code in eclipse. You are writing the code here only.

Write a class called square which inheres the above point class.
A square is described by a point which is one corner of the square and the length
of the side of the square.
Select appropriate variable(s).
Write constructors.
Write access methods for the variables.
Override the inherited print method to display variable in square and point.
Write a test program to test it.

3. (TCOs 1-8) Start from the following code, and add Action Listener to make it functional. The user inputs a temperature in celsius or farenheit in the appropriate textbox, then clicking the arrow will convert and display the result. (Note ONLY code the ACTION LISTENER, you should only need about 10 lines of code)

Note the formula to convert farenheit to celsius:  C = 5/9(F - 32)

import javax.swing.*;
import
java.awt.GridLayout;
import
java.awt.event.*;
import
java.text.DecimalFormat;

public class temperatureConverter extends JFrame {
public static void
main(String[] args) {
JFrame frame = new temperatureConverter();
frame.setTitle("Temp");
frame.setSize(200, 100);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}

public
temperatureConverter() {
JLabel lblC = new
JLabel("C",SwingConstants.CENTER);
JLabel lblF = new
JLabel("F",SwingConstants.CENTER);
final
JTextField jtfC = new JTextField();
final
JTextField jtfF = new JTextField();
JButton jbtLeft = new JButton(" JButton jbtRight = new JButton("=>");

JPanel panel = new JPanel(new GridLayout(2, 3));
panel.add(lblC);
panel.add(jbtLeft);
panel.add(lblF);
panel.add(jtfC);
panel.add(jbtRight);
panel.add(jtfF);

this.add(panel); // Add panel to the frame

final
DecimalFormat dec = new DecimalFormat("#.00");
}
}

4. (TCOs 1-8) Start from the given class, and create a NewPanel class to draw a figure like below: YOU DO NOT have to compile/run this code in eclipse. You are writing the code here only. Need about 15 lines of code.

import javax.swing.*;
import
java.awt.Graphics;
import java.awt.Color;

public class drawFlag extends
JFrame {
public
drawFlag() {
add(new
NewPanel());
}
public static void
main(String[] args) {
drawFlag frame = new drawFlag();
frame.setTitle("Flag");
frame.setSize(200, 200);
frame.setLocationRelativeTo(null); // Center the frame 
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true); 
}
}

The post tip is a solid circle coordinate and size is (68, 28, 4, 4).
The flag tip is a rectangle with coordinate and size is (70, 30, 50, 30).
The text coordinate is (85, 118).
The starting and ending coordinate for the post is (70, 30, 70, 120).
Color blue with text black.
