Explanation of Solution
Given code:
//Definition of class "ExceptionTest"
public class ExceptionTest
{
//Definition of main
public static void main(String[] args)
{
//Declare the variable "number"
int number;
//Declare the variable "str"
String str;
//Try block
try
{
//Assign "xyz" to "str"
str = "xyz";
//Parse the string and store it in //number
number = Integer.parseInt(str);
//Print "A"
System.out.println("A");
}
//Catch block
catch (NumberFormatException e)
{
//Print the value "B"
System.out.println("B");
}

Write down the output of the program and justify why it is the output. Instead of the “replacement” semantics of exception handling used in modern languages, a very early design of exception handling introduced in the PL/I language uses a “binding” semantics. In particular, the design dynamically tracks a
sequence of “catch” blocks that are currently active; a catch block is active whenever the corresponding try block is active. What will be the output of the following program if the language uses the “binding” semantics? Give the reasoning for your answer.

public static void stats(int[] a) {// complete this method}public static void subarray(int[] a, int from, int to) {// error check w/o using Java's exception handlingif (from < 0 || to >= a.length) {System.out.println("Index out of bound");return;}// complete this method}public static void main(String[] args) {// test int[] a = {15, 25, 10, 65, 30, 55, 65};System.out.println("\nGiven array is: " + Arrays.toString(a));stats(a);subarray(a, 1, 4);// test with other arrays}

This is the question -
Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays the message Can't take square root of negative number.
Code I was given -
import java.util.*;
public class SqrtException {
public static void main(String[] args) throws ArithmeticException {
// Write your code here
}
}
