Program Plan Intro

Given code:

//Class definition

public class ChainedExcptionDemo

{

    //Main method

    public static void main (String[ ] args)

    {

        //Try block

        try {

            //Call method() method

            method1() ;

        }

        //Catch block

        catch (Exception ex) {

            // printStackTrace() method displays the

//exception name and description and also //print line name of error

            ex.printStackTrace();

        }

    }

    //Method definition

    public static void method1() throws Exception

    {

        //In try block

        try {

            //Call method() method

            method2() ;

        }

        //Catch block

        catch (Exception ex) {

            //Line16 statement to replace

            //Throw the checked exception

throw new Exception ("New info from method1", ex);

        }

    }

    //Method definition

    public static void method2( ) throws Exception

    {

        //Throw the checked exception

Java Foundations : Please provide code and explain. Thank you. Write the code segments in main( ) and in methodA( ) for the following scenario: main( ) passes methodA an int variable called a. methodA generates an exception, but does not deal with it, if a is not between 1 and 100.

public class Test { public static void main (String [] args) { Object circlel = new Circle (); Object circle2 = new Circle (); System.out.println(circlel.equals (circle2)); class Circle { double radius; class Circle { double radius; public boolean equals (Circle circle) { public boolean equals (Object o) { return this.radius = ( (Circle)o).radius; return this.radius = circle.radius;

What is the difference between using @Test(expected = TypeOfException) and using try/catch when testing if a method or constructor properly returns an exception? A. They do the same thing. B. @Test(expected = ...) is the proper way to unit test in java, and try/catch should only be used when unit testing in Python. C. @Test(expected = ...) will give a passing test as soon as one exception of the proper type is thrown and then stop the test, but using try/catch will allow you to test many examples in the same test and will only stop after running all examples or reaching a fail() or an assert statement that fails. D. We should never use try/catch when unit testing, otherwise we will catch the exception and then won't know if it is actually thrown.
