Here is the source code for the Kitty class:

public class Kitty {

String name;
int age;

public Kitty(){
}

public void setName(String n){
name = n;
}

public String getName(){
return name;
}

public void setAge(int a){
age = a;
}

public int getAge(){
return age;
}
}

1) The array myCats is an 8 element array of type Kitty that has already been declared and initialized. Write the expression(s) in the box below that increases the age of the fifth Kitty by one year:

(Remember: the first element of an array is at index position 0).

2)The array myCats is an 8 element array of type Kitty that has already been declared and initialized. Write the expression(s) in the box below that prints to the console the name of the fourth Kitty if its age is strictly greater than the age of the fifth Kitty, and prints the name of the fifth Kitty otherwise:

(Remember: the first element of an array is at index position 0).

The fifth Kitty is myCats[4], since the index starts from zero.

Each member of the array myCats is a Kitty object.

1)
To increase the age, you need to get the age of myCats[4], add one to it, and put back the increased age. This is how you can do it:
myCats[4].setAge(myCats[4].getAge()+1);

2)
int age4=myCats[3].getAge();
int age5=myCats[4].getAge();
if(age4>age5)
{
System.out.print(myCats[3].getName());
} else
{
... to be completed by you ...
}

System.out.print(myCats[4].getName());

1) To increase the age of the fifth Kitty by one year, you would use the following expression:

myCats[4].setAge(myCats[4].getAge() + 1);

Explanation:
- "myCats[4]" refers to the fifth element in the array, since the first element is at index position 0.
- "myCats[4].getAge()" retrieves the age of the fifth Kitty.
- "+ 1" increases the age by one.
- "myCats[4].setAge()" sets the new age for the fifth Kitty.

2) To print the name of the fourth Kitty if its age is strictly greater than the age of the fifth Kitty, and the name of the fifth Kitty otherwise, you would use the following expression:
if (myCats[3].getAge() > myCats[4].getAge()) {
System.out.println(myCats[3].getName());
} else {
System.out.println(myCats[4].getName());
}

Explanation:
- "myCats[3]" refers to the fourth element in the array, since the first element is at index position 0.
- "myCats[3].getAge()" retrieves the age of the fourth Kitty.
- "myCats[4]" refers to the fifth element in the array, since the first element is at index position 0.
- "myCats[4].getAge()" retrieves the age of the fifth Kitty.
- The if statement compares the ages and executes the code block inside the curly brackets if the condition is true.
- "System.out.println(myCats[3].getName())" prints the name of the fourth Kitty.
- The else block executes if the condition in the if statement is false.
- "System.out.println(myCats[4].getName())" prints the name of the fifth Kitty.

1) To increase the age of the fifth Kitty by one year, you would need to use the following expression:

myCats[4].setAge(myCats[4].getAge() + 1);

Explanation:
- The expression "myCats[4]" accesses the fifth element of the array "myCats" because array indices start from 0.
- The method "setAge()" is then called on the accessed Kitty object to set the new age.
- Within the "setAge()" method, we use "myCats[4].getAge()" to get the current age of the fifth Kitty and add 1 to it.
- Finally, the updated age value is passed to "setAge()" to set the new age for the fifth Kitty.

2) To print the name of the fourth Kitty if its age is strictly greater than the age of the fifth Kitty, and print the name of the fifth Kitty otherwise, you would need to use the following expression:

if (myCats[3].getAge() > myCats[4].getAge()) {
System.out.println(myCats[3].getName());
} else {
System.out.println(myCats[4].getName());
}

Explanation:
- The expression "myCats[3].getAge()" accesses the fourth element of the array "myCats" to get the age of the fourth Kitty.
- The expression "myCats[4].getAge()" accesses the fifth element of the array "myCats" to get the age of the fifth Kitty.
- The "if" statement compares the two ages to check if the age of the fourth Kitty is strictly greater than the age of the fifth Kitty.
- If the condition is true, the name of the fourth Kitty is printed using "myCats[3].getName()".
- If the condition is false, the name of the fifth Kitty is printed using "myCats[4].getName()".
- The "System.out.println()" statement is used to print the name of the respective Kitty to the console.
