Hello AnithaBabu1.

Welcome to the Java Programming Forums!

Try this:

class userException extends Exception
{
int age;
 
userException(int age)
{
age=age;
}
 
public String toString()
{
return"UserException caught:invalid age";
}}
 
 
class userExceptionDemo
{
static void calculate(int age) throws userException
{
 
if(age<18||age>22)
throw new userException(age);
System.out.println("valid age");
}
 
public static void main(String args[])
{
 
System.out.println("Enter age: ");
 
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr);
String s = br.readLine();
int age = Integer.parseInt(s);
 
try
{
 
calculate(age);
calculate(age);
 
}
catch(userException obja)
{
System.out.println("caught:"+obja);
}
}
}

This code takes input from the console.

Try putting this part of the code into a try catch block..

System.out.println("Enter age: ");
 
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr);
[COLOR=red]String s = br.readLine();[/COLOR]
int age = Integer.parseInt(s);
