You will write one object class for each part, and you will use the provided Java applications to test your completed object classes. Each of your object classes ust be arranged in the following three sections, each marked with a comment: instance variables, constructor(s). and instance metbods. You toString methods should return a String containing all instance variables in a sentence, with any instance variables representing monetary values formatted as money formatted to two decimal places. HnnsTips: Though the details of cach class are different, the steps to take in writing your object classes are the same steps taken in Lecture 23 to write the LightSwitch class. As usual, it is a good idea to write your class one section or method at a time, testing for compilation after each. You can also write short test applications that test the completed methods before all the methods are written and ready for the final test program. Tasks Part A. Design and implement a Java object class named Martian that simulates a martian, and test it using the supplied Java application PartADriverjava. Your Martian class ust meet the 1. A Martian should be represented by the following attributes (i e, instance variables) e a name an integer number of legs an integer number of times that the Martian has spoken 2. Your Martian class must implement the methods shown in the attacbed API All methods should behave as descibed in the API (see details of he speak method below). 3. The speak method will output a message as follows. If the Martian has previously spoken an even mumber of times, the method should output name says: Burble!. where name is replaced with the name of tbe Martian. If the Martian has previously spoken an odd umber of times, the method should instead output"name says: Take me to yourleader." (where name is again replaced with the name of the Martian) 0 Once your Martian class compiles test it by compiling and running the PartADriverjava application Submit the output along with your source code file.

PartADriver

public class PartADriver
{
   public static void main (String [] args)
   {
// create two martians
Martian m1 = new Martian();
Martian m2 = new Martian("Grey", 3);

// display both martians
Output.showMessage("After instantiation.\n" +
"Martian #1: " + m1.toString() +
"\nMartian #2: " + m2.toString());

// make the first martian speak 3 times
for (int count = 0; count < 3; count++)
   m1.speak();

// make the second martian speak once
m2.speak();

// display both martians
Output.showMessage("After speaking.\n" +
"Martian #1: " + m1.toString() +
"\nMartian #2: " + m2.toString());

// try some other methods
m1.setName("Martin");
m2.setNumLegs(7);
Output.showMessage("After calling some setters.\n" +
"Martian #1: " + m1.toString() +
"\nMartian #2: " + m2.toString());

if (m1.getNumLegs() > m2.getNumLegs())
   Output.showMessage(m1.getName() + " has the most legs.");
else
   Output.showMessage(m2.getName() + " has the most legs.");

   } // method main
} // class PartADriver

Answer 1

Here i hvae create two class Martian and PartADriver

Code for partadriver project

package partadriver;
//class Martian
class Martian
{
//class variable
String Name;
int Legs;
int speackcount;//for counting speak
//defualt constractor
Martian()
{
speackcount=0;
}
//perameterize constractor
Martian(String name,int numLegs)
{
Name=name;
Legs=numLegs;
speackcount=0;
}
//get name
public String getName()
{
return Name;
}
//get number of legs
public int getNumLegs()
{
return Legs;
}
//set name
public String setName(String name)
{
this.Name=name;
return Name;
}
//set number of legs
public int setNumLegs(int numLegs)
{
this.Legs=numLegs;
return Legs;
}
//method speak
public void speak()
{//if even
if(speackcount%2==0)
{
System.out.println(Name+" says: Burble!");
}
//else odd
else
{
System.out.println(Name+" says: Take me to your leader!");
}
speackcount++;
}
//to string
public String toString()
{
return "name"+Name+" Legs"+Legs;
}
}
public class PartADriver
{

public static void main(String[] args)
{
// create two martians
Martian m1 = new Martian();
Martian m2 = new Martian("Grey", 3);
m1.setName("Blue");
m1.setNumLegs(2);
// display both martians
System.out.println("After instantiation.\n" +
"Martian #1: " + m1.toString() +
"\nMartian #2: " + m2.toString());

// make the first martian speak 3 times
for (int count = 0; count < 3; count++)
m1.speak();

// make the second martian speak once
m2.speak();

// display both martians
System.out.println("After speaking.\n" +
"Martian #1: " + m1.toString() +
"\nMartian #2: " + m2.toString());

// try some other methods
m1.setName("Martin");
m2.setNumLegs(7);
System.out.println("After calling some setters.\n" +
"Martian #1: " + m1.toString() +
"\nMartian #2: " + m2.toString());

if (m1.getNumLegs() > m2.getNumLegs())
System.out.println(m1.getName() + " has the most legs.");
else
System.out.println(m2.getName() + " has the most legs.");
}
  
}

Output:
