Aim:
To perform the Exception handling concept in the java programming language.
Algorithm:
Step1: Create a new text document and type the java program for implementing the
exception handling concept.
Step2: Create a parent class named “Examfinally”.
Step3: Intialize the variable “a=65” as integer and “b=0” as integer in the main
program.
Step4: “try” block is the used to handling the errors, and “catch” block is used to
handling the errors.
Step5: “finally” block is used to execute the program for run the program upto the
last line.
Step6: Save the program using “.java” command.
Step7: Compile and run the program using “javac” and “java” commands.
Program
class Examfinally
{
public static void main(String arg[])
{
int a;
try
{
a=Integer.parseInt(arg[0]);
}
catch(ArithmeticException e)
{
System.out.println("Error:"+e);
}
catch(ArrayStoreException e1)
{
System.out.println("Error:"+e1);
}
catch(ArrayIndexOutOfBoundsException e2)
{
System.out.println("Error:"+e2);
}
finally
{
System.out.println("I am Always Executed....");
}
}
}
OUTPUT:
(B).Throws Statement
Aim:
To perform the exception handling concept in the java programming language.
Algorithm:
Step 1: Create a new text document and type the java program for implementing the
exception handling concept.
Step 2: “import” keyword is used to import the java program.
Step 3: Create a parent class named “ExamThrows”.
Step 4: Intialize the variable “v=0” as integer and “ch” as character.
Step 5: “switch” statement is used to check the option cases and print the option case
which is selected.
Step 6: Save the program using “,java” command.
Step 7: Compile and run the program using “javac” and “java” commands.
Program
import java.io.*;
class ExamThrows
{
public static void main(String args[])throws IOException
{
int v=0;
char ch;
while((ch=(char)System.in.read())!='.')
{
switch(ch)
{
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':v++;
System.out.println("numbers of vowels:"+v);
}
}
}
}
