Customized Exceptions and Types of Error in Java

Customized Exceptions Sometimes during creating a program, there is a requirement of some special exception which is not available. So in such situation Java gives us the facility to create our own exceptions called as customized exceptions. Consider the following example of a customized_exception,


import java.util.Scanner;
class TooYoungException extends RuntimeException
{
    TooYoungException(String str)
    {
        super(str);
    }
}
class TooOldException extends RuntimeException
{
    TooOldException(String str)
    {
        super(str);
    }
}
public class ExampleOne
{
    public static void main(String []args)
    {
        Scanner s = new Scanner(System.in);
        System.out.println("Enter your current age: ");
        int age = s.nextInt();
        if(age > 60)
        {
            throw new TooOldException("You are too old to get married.");
        }
        else if(age < 18)
        {
            throw new TooYoungException("You are too young to get married.");
        }
        else
        {
            System.out.println("You will get the details of the match by the email.");
        }
    }
}

import java.util.Scanner;

class TooYoungException extends RuntimeException

{

TooYoungException(String str)

{

super(str);

}

class TooOldException extends RuntimeException

{

TooOldException(String str)

{

super(str);

}

public class ExampleOne

{

public static void main(String []args)

{

Scanner s = new Scanner(System.in);

System.out.println("Enter your current age: ");

int age = s.nextInt();

if(age > 60)

{

throw new TooOldException("You are too old to get married.");

}

else if(age < 18)

{

throw new TooYoungException("You are too young to get married.");

}

else

{

System.out.println("You will get the details of the match by the email.");

}

Output of the above code will be:


Enter your current age: 25
You will get the details of the match by the email.

Enter your current age: 25

You will get the details of the match by the email.

Note- A good […]
