Question
Some of the class here have already answered but I needed the code asap implementing the exception for JOptionPane, Exam Questions, Factorial, Number to Words, Pyramid and Address Book.
Only NetBeans project compressed in .rar or .zip format will be accepted.
1. ArrayIndexOutOfBoundsException <-- Question answered
Given the following code:
public class ExceptionTest{
public static void main( String[] args ){
String nums[] = {“one”, “two”, “three”};
for( int i=0; i<=3; i++ ){
System.out.println(nums[i]);
}
}
}
Compile and run the TestExceptions program. The output should look like this:
one
two
three
Exception in thread "main"
java.lang.ArrayIndexOutOfBoundsException: 3
at ExceptionTest.main(1.java:4)
Modify the TestExceptions program to handle the exception. The output of the program after catching the exception should look like this:
one
two
three
Exception caught: Array Index 3 is out of bounds
2. Catching Exceptions
Implement Exception handling for the programs you have written in the laboratory exercises as listed below. Note that all data to be used for processing must be input data (data entry from the user). When an invalid data is entered, the program should loop back to data entry until the input becomes valid.
Lab Exercise 003 – Circle Calculator(Question answered for Circle Calculator) and JOptionPane
Lab Exercise 004 – Exam Questions, Factorial, Number to Words, Pyramid
Lab Exercise 007 – Address Book
Sample Output:
I don't have a code for JOptionPane but I also request for having the code for it implementing exception.
Here is my code for Exam Questions without implementing exception:
package Week6;
import java.util.Scanner;
public class examprogram {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int score =0;
double percentage;
System.out.println("Who is the first President of the Philippines?"
+ " 1.Emilio Aguinaldo"
+ " 2.Joseph Estrada"
+ " 3.Manuel Quezon"
+ " 4.GMA");
System.out.print("Enter [1-4]:");
int Ans1 = scan.nextInt();
if(Ans1==1){
System.out.println("Correct ");
score ++ ;
}
else{
System.out.println("Incorrect! The Correct answer is 1.Emilio Aguinaldo ");
}
System.out.println("Hitler party which came into power in 1933 is known as?"
+ " 1.Labour"
+ " 2.Nazi Party"
+ " 3.Ku-Klux-Klan"
+ " 4.Democratic Party");
System.out.print("Enter [1-4]:");
int Ans2 = scan.nextInt();
if(Ans2==2) {
System.out.println("Correct ");
score ++ ;
}
else {
System.out.println("Incorrect! The Correct answer is 2.Nazi Party ");
}
System.out.println("For which of the following discipline is Nobel Prize awarded?"
+ " 1.Physics and Chemistry"
+ " 2.Physiology or Medicine"
+ " 3.Literature, Peace and Economics"
+ " 4.All of the above");
System.out.print("Enter [1-4]:");
int Ans3 = scan.nextInt();
if(Ans3==4){
System.out.println("Correct ");
score ++ ;
}
else{
System.out.println("Incorrect! The Correct answer is 4. All of the above ");
}
System.out.println("What is 3*(2-1)?"
+ " 1. 1"
+ " 2. 2"
+ " 3. 3"
+ " 4. 4");
System.out.print("Enter [1-4]:");
int Ans4 = scan.nextInt();
if(Ans4==3){
System.out.println("Correct ");
score ++ ;
}
else{
System.out.println("Incorrect! The Correct answer is 3. 3 ");
}
System.out.println("What is 1+1?"
+ " 1. 1"
+ " 2. 2"
+ " 3. 3"
+ " 4. 4");
System.out.print("Enter [1-4]:");
int Ans5 = scan.nextInt();
if(Ans5==2){
System.out.println("Correct ");
score ++;
}
else{
System.out.println("Incorrect! The Correct answer is 2. 10 ");
}
percentage = (score * 100)/5;
System.out.println("Congratulations!, you got answers right! "+ score);
System.out.println("That is a score of " + percentage + " percent.");
}
}
I don't have a code for Factorial but I also request for having the code for it implementing exception.
Even the instruction says specifically for negative values, I also needed the code for any invalid input like letters etc.
Here is my code for Number to Words without implementing exception:
package Week6;
import java.util.Scanner;
public class numbertowords {
public static void main(String[] args) {
Scanner input =new Scanner(System.in);
System.out.print(" Enter number: ");
int num =input.nextInt();
String s1[]={ " One"," Two"," Three"," Four"," Five"," Six"," Seven"," Eight", " Nine", " Ten", " Eleven", " Twelve",
" Thirteen", " Fourteen", " Fifteen", " Sixteen",
" Seventeen", " Eighteen", " Nineteen"};
String[] s2 = {" ten",
" Twenty",
" Thirty",
" Forty",
" Fifty",
" Sixty",
" Seventy",
" Eighty",
" Ninety"
};
String[] s3={" Hundred",
" Thousand",
" Ten thousand",
" Hundred thousand"};
int i=num;while(i>0)
{
if(i>=1&&i<=19)
{System.out.println(s1[i-1]);break;}
else if(i>=20&&i<=99)
{
int l=i%10;
i=i-l;
i=i/10;
System.out.println(s2[i-1]+""+s1[l-1]);break;
}
else if(i>=100&&i<=999){
int l=i%100;
int k=i-l;
k=k/100;
System.out.print(s1[k-1]+""+" Hundred");
i=i-(k*100);
}
else if(i>=1000&&i<=9999){
int l=i%1000;
int k=i-l;
k=k/1000;
System.out.print(s1[k-1]+""+" Thousand");
i=i-(k*1000);
}
else if(i>=10000&&i<=99999){
int l=i%10000;
int k=i-l;
k=k/10000;
System.out.print(s2[k-1]);
i=i-(k*10000);
}
if(num>=100001){
System.out.println(" Number is out of range");break;
}
else if(num==100000){
System.out.println(" One Hundred Thousand"); break;
}
}
}
}
Here is my code for Pyramid without implementing exception:
package Week6;
import java.util.Scanner;
public class PrintHalfPyramid {
public static void main(String[] args) {
Scanner input =new Scanner(System.in);
System.out.print("Enter number: ");
int num =input.nextInt();
for (int i = 0; i < num; i++) {
for (int j = 0; j < i - i; j++) {
System.out.print(j+1);
}
for (int k = 0; k <= i; k++) {
System.out.print("* ");
}
System.out.println();
}
}
}
Here is my code for Address Book without implementing exception:
package lab7_nunez_maryaileen;
import java.util.Scanner;
class AddressBook
{
//attributes

private String Address;//Address of the person
