If you change the code in line 33 in Listing 24.2, MyArrayList.java, from
E[] newData = (E[])(new Object[size * 2 + 1]);
to
E[] newData = (E[])(new Object[size * 2]);

7. See the code below and solve the following.
public class Test {
public static void main(String[] args) {
int result = 0;
}
result = fn(2,3);
System.out.println("The result is:
+ result);
// fn(x, 1) = x
// fn(x, y)
=
fn(x, y-1) + 2, when y>1
public static int fn(int x, int y) {
if (x <= 1)
return x;
else
return fn(x, y-1) + 2;
}
}
7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix
the problem. (2 point)
7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point)
7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)
6. See the code below and solve the following.
import java.io.*;
public class DataStream {
}
public static void main(String[] args)
}
DataOutputStream output = new DataOutputStream(new FileOutputStream("temp.dat"));
output.writeUTF("Book1");
output.writeInt(85);
output.writeUTF("Book2");
output.writeInt(125);
output.writeUTF("Book3");
output.writeInt(70);
output.close();
// ToDo: Read all data from temp.dat and print the data to the standard output (monitor)
6-1. This program has a compile error, and the message is “Unhandled exception type
FileNotFoundException". How do you fix this error? (1 point)
6-2. Is FileNotFoundException a checked exception or an unchecked exception? (1 point)
6-3. What is the difference between checked exception and unchecked exception? (1 point)
6-4. Please complete the above program by reading all data from temp.dat and print the data
to the standard output (monitor) by using System.out.print, System.out.println or
System.out.printf method. (2 points)
Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume the list will contain a maximum of 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline.
Hints: - use a for loop to populate the array based on the specified size (the first number entered)
- use a for loop to check first value with last value, second value with second from end, etc.
- if the values do not match, set a Boolean variable to flag which statement to output (yes or no)
Ex: If the input is (remember to include spaces between the numbers):
6 1 5 9 9 5 1
the output is:
yes
Ex: If the input is:
5 1 2 3 4 5
the output is: C++ coding
