Concept explainers
a.
Finally block:
Finally block contains block of code and the block is executed after a try-catch block.
- If there is no errors in try block, finally statement is executed after try block executed.
- If there is error in try block, then catch block caught the exception, rest of try block is skipped, and then executes the finally statement.
- If there is error in try block, then catch block does not caught that exception, rest of try block is skipped, executes only finally statement, and then skip the rest of the code.
- Thus, finally block handle such case and it contains block of statement. Once try-catch block gets executed, finally block is executed.
General form for finally block:
// class definition
class class_name
{
//...
// Try block
try
{
// Try block statement
}
// Catch block
catch(Excep1 exObj)
{
// Catch block statement
}
// Catch block
catch(Excep2 exObj)
{
// Catch block statement
}
//...
//Finally block
finally
{
//finally block statement
}
//...
}
Given code:
//Try block
try
{
statement1;
statement2;
statement3;
}
//Catch block
catch (Exception1 ex1)
{
}
//Finally block
finally

Introduction to Java Programming and Data Structures, Comprehensive Version (11th Edition)
- Q4: Write a program that performs exception handling. A class should have two exception handling classes. This program throws an exception of type both classes (user defined data types) and they are catched in a catch block. This class also throws an exception of built-in data types (of your choice). Also in your program include a catch block for all data types. Write a simple C++ code as i am a begineer.arrow_forwardSuppose that statement2 causes an exception in the following try-catch block: try{statement1;statement2;statement3; }catch (Exception1& ex1) {}catch (Exception2& ex2) {} statement4; Answer the following questions: Will statement3 be executed? If the exception is not caught, will statement4 be executed? If the exception is caught in the catch block, will statement4 be executed?arrow_forwardSubject: Object Oriented PrgrammingLanguage: Java ProgramTopic: Exception Define a new exception, called ExceptionLineTooLong, that prints out the error message "The strings is too long".

- Modify the GreenvilleRevenue program created in Chapter 10, Case Study 1 so that it performs the following tasks: The program prompts the user for the number of contestants in this year’s competition; the number must be between 0 and 30. Use exception-handling techniques to ensure a valid value and display the error message:Number must be between 0 and 30 The program prompts the user for talent codes. Use exception-handling techniques to ensure a valid code and update the displayed message to the following message:x is not a valid talent code. Assigned as Invalid.where x was the invalid code entered into the console. After data entry is complete, the program prompts the user for codes so the user can view lists of appropriate contestants. Use exception-handling techniques for the code verification and display the following message: Enter a talent type or Z to quit >> x x is not a valid code and for valid codes: Enter a talent type or Z to quit >> S Contestants with talent…arrow_forwardModify the GreenvilleRevenue program created in Chapter 10, Case Study 1 so that it performs the following tasks: The program prompts the user for the number of contestants in this year’s competition; the number must be between 0 and 30.

Do not use input, output. Please provide code and explain. Thank you. Write the Java code for the following: Write the InvalidGradeException class that will be used below. Write the Java program that reads an integer grade from a user and checks that it is valid (between 0 and 100). If it is invalid an InvalidGradeException will be thrown, stating what the invalid grade is. This will be caught in the main( ) method which will write a message about the invalid grade. If the grade is valid, it is written to the monitor..arrow_forward
- Define an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using zero-argument constructor, getMessage should return "Cor Breach Evacuation Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using constructor, getMessage should return the value that was used as an argument to constructor.arrow_forwardAdvanced programming applications using javaarrow_forwardThe code with the discussion of itarrow_forward
