the errors arriving during the execution of a program when there is a mistake of the programmer in applying the correct mathematical logic
eg: int a= 5;
int b=0;
System.out.print(a/b);
System.out.print("correct answer");
in this eg. a runtime error will be shown and to remove it we can use try catch block

A program to explain the Exception Handling mechanisms in Java using the keywords try catch and finally?
Here is a code snippet illustrating exception handling: try { int a= 3 / 0 ; } catch ( ArithmeticException e ) { System.out.println ("An ArithmeticException has occured"); } finally { // some code }
What are the errors in object oriented program?
In Java, errors that arise during the execution of the program are more formally referred to as Exceptions. Exceptions can be handled using try catch blocks. Here is an example : try { int answer = 42 / 0 ; } catch ( ArithmeticException e ) { e.printStackTrace(); }
What a java program for arithmetic operations between two integers?
public static void main(String[] args) { int a = 5; int b = 10; int c; c = a + b; // addition c = a - b; // subtraction c = a * b; // multiplication c = a / b; // division }
What is throw keyword in java?
The throw keyword is used from within a method to "throw" an exception to the calling method. In order to throw an exception, the method signature must indicate that it will throw an exception. For example: public void foo() throws Exception { } When you want to actually throw the exception, you can do it a few different ways: throw new Exception("Exception message"); or from within a catch block ( catch(Exception ex) ): throw ex;
Define an exception called NoMatchException that is thrown when a string is not equal to Symbiosis Write a Java program that uses this exception?
import java.util.Scanner; class NoMatchException extends Exception { static void method() throws Exception{ String s = "India"; String s2 = " "; try { if (!s.equals(s2)){ throw new NoMatchException(); //System.out.println("Strings are equal"); } else { System.out.println("Strings are equal"); //throw new NoMatchException(); } } catch(NoMatchException ne){ System.out.println("Exception Found For String"); } finally { System.out.println("In Finally Block"); } } } public class BasicException { static void myMethod(int x, int y) throws Exception{ try { if(x < y ) { System.out.println("Y is greater then X"); throw new Exception(); } else System.out.println("Y is smaller"); } catch(Exception ex) { System.out.println("exception found"); //System.out.println(ex.toString()); } finally { System.out.println("FINALLY block"); } } public static void main(String args[]) throws Exception{ Scanner s = new Scanner(System.in); int d, a, x, y; System.out.println("Enter the value of x and y"); x = s.nextInt(); y = s.nextInt(); try { BasicException.myMethod(x , y); }catch(Exception e) { System.out.println("main method exception"); System.out.println(e.toString()); } try { NoMatchException.method(); } catch(NoMatchException e) { System.out.println("Exception Caught"); } try{ d=0; a=42/d; System.out.println("This will not be printed."); } catch(ArithmeticException e){ System.out.println("Division by zero."); } } }
Which operations are capable of throwing an ArithmeticException?
% and /
Give you an example of each type of Exception in Java through programs?
// A method which throws an exception. // Declare an ArithmeticException to be thrown. int integerDivision(int a, int b) throws ArithmeticException { // If we try to divide by zero, throw our exception... if(b == 0) { throw new ArithmeticException("Division by 0"); } // ...otherwise, return our result. return a/b; } // A method which catches an exception. void doSomeDivision() { // Let's divide each integer [0,9] by one another... for(int a = 0; a < 10; ++a) { for(int b = 0; b < 10; ++b) { // Try to do the division... try { final int q = integerDivision(a,b); System.out.println(a + " / " + b + " = " + q); } catch(ArithmeticException ex) { // ...end up here in case of Exception System.out.println("Cannot divide " + a + " by " + b); } } } }

What type of error is encountered if a program performs a division by zero?
Depends entirely on the programming language in question. Examples: C#: DivideByZeroException Java: ArithmeticException Python: ZeroDivisionError C++: No exception, let's the CPU it's been compiled for handle it. So whatever it would do in Assembly/Machine is what it does.
What is the use of throws in java?
The throw keyword in java causes a declared exception to be thrown. For example, if you want to mark an error in a method that add two numbers if any of then is negative you can write something like this:public int addMethod( int a, int b ){if ( a < 0 b < 0 ){throw new ArithmeticException("negative addition");}return a + b;}The previous code cause a ArithmeticException if some try to add negative numbers.
What is exception and list some of the common type of exception?
Exceptions are thrown when Java encounters an error. They are a fundamental part of the Java error handling system. In a nutshell, Java will throw an Exception when it encounters an error so that an exception handler can "handle" the error. For instance, if a calculator program is given the command "1/0", Java can throw an ArithmeticException which could be reported back to the user.Some common types are:ArithmeticException - thrown when arithmetic error has occurred, like dividing by 0IOException - thrown when an input or output error has occurred, like a file not foundArrayIndexOutOfBoundsException - thrown when a nonexistent element of an array is requested, like arr[-1]NullPointerException - thrown when some operation if performed on an object whose value is nll.
