Java throw keyword Example

class ArithmaticTest{
    public void division(int num1, int num2){
            //java.lang.ArithmeticException here.

        }catch(ArithmeticException e){
            //throw exception.
            throw e;

      System.out.println("Remaining code after exception handling.");

public class ExceptionThrowExample {
    public static void main(String args[]){
        //creating ArithmaticTest object
        ArithmaticTest obj =  new ArithmaticTest();
        //method call
        obj.division(20, 0);
