Identifiers declared inside a block: scope { // block begins int x; // local in block x = 9; System.out.println(x) ; } // block ends have block scope, are called local variables and are visible only inside the block. Local variables in different blocks may have the same name. What is the output of the program? public static void main (String[] a) { int x; // local in main x = 1; } System.out.println("Main x methodl () ; void methodl () { System.out.println ("Main x " + x); method2 () ; + x); int x = 0; // local in method System.out.println("methodl x"+ x); void method2 () { System.out.println ("method2 *"+ x);

(HexFormatException)Implement the hex2Dec function in Programming Exercise 16.1 to throw a HexFormatException if the string is not a hex string .Define a custom exception class named HexFormatException. Write a test program that prompts the user to enter a hex number as a string and displays the number in decimal. If the function throws an exception, display "Not a hex number".
There are two styles of working with blocks where you explicitly work with an object provided as a block argument, or where you implicitly work with the object and there are no block arguments.Write an example of the approaches:
Complete a program that reads a vector index as input and outputs the element of a vector of 10 names at the index specified by the input. Use a try block to output the name and a catch block to catch any out_of_range exceptions. When an out_of_range exception is caught, output the message from the exception object and the first element in the vector if the index is negative or the last element if the index is greater than the size of the vector. Hint: Format the exception outputs using the what() function from the exception object. Do not hard code the exception messages. Ex: If the input of the program is: 5 the program outputs: Jane Ex: If the input of the program is: 12 the program outputs: Exception! vector::_M_range_check: __n (which is 12) >= this->size() (which is 10) The closest name is: Johnny Ex: If the input of the program is: -2 the program outputs: Exception! vector::_M_range_check: __n (which is 18446744073709551614) >= this->size() (which is 10) The closest…
in pytrhon programming language, What happens when an unhandled exception occurs? The finally clause executes, and the code finishes. The finally clause executes, and the code returns -1. The finally clause executes, and then the exception is re-raised. The finally clause executes, and then runs the try block again.

Inside the try block, the function set_weight( ) is to be called with the argument weight. In the catch block, pass the exception message via << to std::cout Then weight_ is to be set in the following way: If range is smaller than 10, weight_ should be set to range In all other cases weight_ is to be set to weight_ times -1 After the try-catch block, proceed as follows: Assigned range to…

The block is practically a square-size placeholder for the Tile objects. But not all the spots are necessarily occupied. When the block is generated, we randomly pick the spots that will be filled in with tiles. All the tiles of a block must have the same color. write the code for these functions below private DynamicArray<DynamicArray<Tile>> block; // the internal storage of the block data public Block(int y, int x, int size) // this contructor creates a 2D placeholder of null value; //these values will be populated later with calls to setTile() public Block(int y, int x, int size, byte color) // overloaded constuctor that creates a 2D matrix with actual tile objects; //no need to call setTile afterwards
(Local Variable Destructors) Write a program illustrating that all destructors for objectsconstructed in a block are called before an exception is thrown from that block.
Arguments to a catch block are not restricted in number.
In c++ implement function getPercentage that takes two inputs: grade and total Grade and outputsthe gradepercentage as follows: percentage = (grade/total grade)*100 . (Assume a student can notget a grade above 100%)Define your own exception classes:1. DivideByZeroException as a derived class of Standard Library class runtime_error,that is used to detect division by zero run time error.2. NegativeNumberException as a derived class of Standard Library class logic_error,that is used to detect if the user entered a negative number as a grade.3. InvalidGradeException as a derived class of Standard Library class logic_ error, thatis used to detect if a user entered an invalid input (grade greater than total grade).Use the above exception classes after implementing them to apply exception handling foryour getPercentage function.
