HANDLING EXCEPTIONS AND EVENTS - Java Programming: From Problem Analysis to Program Design - page 750

Example 11-7 shows how to rethrow an exception caught by a catch block.

EXAMPLE 11-7

Consider the following Java code:
//RethrowExceptionExmp1

import java.util.*;

public class RethrowExceptionExmp1
{

static Scanner console = new Scanner(System.in);

public static void main(String[] args) //Line 1

{

int number; //Line 2

try //Line 3

{

number = getNumber(); //Line 4

System.out.println("Line 5: number = "
+ number); //Line 5

}
catch (InputMismatchException imeRef) //Line 6

{

System.out.println("Line 7: Exception "
+ imeRef.toString()); //Line 7

}

}

public static int getNumber()
throws InputMismatchException //Line 8

{

int num; //Line 9

try //Line 10

{

System.out.print("Line 11: Enter an "
+ "integer: "); //Line 11

num = console.nextInt(); //Line 12

System.out.println(); //Line 13

return num; //Line 14

}
catch (InputMismatchException imeRef) //Line 15

{

throw imeRef; //Line 16

}

}

}
