Exercise 12.1: Exception Handling

Introduction:

If you are new to Exception handling, please read "Exception Handling Statements" section of the Java Progamming Tutorial.

Steps to follow:

1. Write ExceptionExample.java as shown in Code-12.1 below. (You are welcome to do this work using either command line tools or NetBeans. The instruction here is given using command line tools. In general, using NetBeans is highly recommended.)

* cd \myjavaprograms
* mkdir exceptionexercise (to match the packaging structure)
* jedit exceptionexercise\ExceptionExample.java
EXAMPLES
package exceptionexercise;

public class ExceptionExample {
public static void main( String[] args ){

try{
System.out.println( args[1] );
} catch( ArrayIndexOutOfBoundsException exp ){
System.out.println("Exception caught! The exception is " + exp);
}
}
}
2. Compile and run the code using a directory structure.

* cd \myjavaprograms (if you are not in this directory already)
* javac exceptionexercise\*.java
* java -classpath . exceptionexercise.ExceptionExample

3. Verify the result

* C:\myjavaprograms>java -classpath . exceptionexercise.ExceptionExample
Exception caught!
