JAVA

Question

Hello world!
I am a new Java learner and have a doubt regarding one of pro challenge about multiple exception (try/catch); my code works and output the correct answer as per test 2 verification but it tells me that is not a valid answer.
I would like just to understand why, for more details here below the details and the code.
Thanks a lot for your help!

Multiple Exceptions

You need to write a divider program which will operate with integers,
The program you are given should take two integers as input and execute the division, but we need to handle two exceptions:
1. the divider shouldn't be zero
2. both inputs should be integers.
Complete the program to handle them. For the first exception, the program should output "Еrror: division by zero"; and for the second one, "Error: wrong value type".

Sample Input
1
b

Sample Output
Error: wrong value type
Use ArithmeticException for first exception and InputMismatchException for the second one.

Code:

import java.util.Scanner;
import java.util.InputMismatchException;

public class Main
{
public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

try {
int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
/*
1. Еrror: division by zero
2. Error: wrong value type
*/
//your code goes here
int num3 = num1/num2;

System.out.println(num3);

} catch(ArithmeticException e1) {
System.out.print("Error: division by zero");

} catch(InputMismatchException e2){
System.out.println("Error: wrong value type");

}
}
}

int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
System.out.println(num1/num2);
} catch(ArithmeticException e) {
System.out.println("Еrror: division by zero");

}
}
}

Answer 2

import java.util.Scanner;
import java.util.InputMismatchException;

public class MultipleExceptions
{
public static void main(String[] args) {

try {
Scanner scanner = new Scanner(System.in);
//System.out.println("Enter two numbers ");

int num1 = scanner.nextInt();

int num2 = scanner.nextInt();

System.out.println(num1/num2);

} catch(ArithmeticException e) {
System.out.println("Error: division by zero");

} catch(Exception e){
System.out.println("Error: wrong value type");

}
}
}

Yes it's weird because the string written in another language like Russian.

Some characters looks like same in many languages but their ASCII value maybe different.

Answer 4

import java.util.Scanner;
import java.util.InputMismatchException;

public class MultipleExceptions
{
public static void main(String[] args) {

try {
Scanner scanner = new Scanner(System.in);
//System.out.println("Enter two numbers ");

int num1 = scanner.nextInt();

int num2 = scanner.nextInt();

System.out.println(num1/num2);

} catch(ArithmeticException e) {
System.out.println("Error: division by zero");

} catch(Exception e){
System.out.println("Error: wrong value type");

}
}
}

import java.util.Scanner;
import java.util.InputMismatchException;

public class Main
{
public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

try {
int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
System.out.println(num1/num2);

} catch(ArithmeticException ex) {
System.out.print("Mistake: division by zero");

} catch(InputMismatchException ex){
System.out.println("Mistake: wrong value type");

}
}
}

Answer 6

OK, it is weird but once I made copy/paste the String "Error: division by zero" from the previous comment on the exercise it finally worked!!

Answer 7

import java.util.Scanner;
import java.util.InputMismatchException;

public class Main
{
public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

try {
int num1 = scanner.nextInt();
int num2 = scanner.nextInt();
/*
1. Еrror: division by zero
2. Error: wrong value type
*/
//your code goes here
int num3 = num1/num2;

System.out.println(num3);

} catch(ArithmeticException e1) {
System.out.print("Еrror: division by zero");

} catch(InputMismatchException e2){
System.out.println("Error: wrong value type");

}
}
}

import java.lang.*;

class Main {
public static void main(String[ ] args) {
Name name = new Name();
//set priority
name.setPriority(5);

Welcome welcome = new Welcome();
//set priority
welcome.setPriority(5);

welcome.start();
name.start();
}
}

//extend the Thread class
class Welcome extends Thread{
public void run() {
System.out.println("Welcome!");
}
}

//extend the Thread class
class Name extends Thread{
public void run() {
System.out.println("Please enter your name");
}
}
