In java proramming handling exceptional circumstances.
In java programming handling exceptional circumstances.
As programmers we should handle these cases in order to present user interactions with users and let the program continues normally, instead of leaving programing crashed or die, its called "EXCEPTION HANDLING".
Here we see the simple program of java : Exception Handling , using TRY & CATCH blocks.
SAVE this program same name of class - Example : Exception.java (java is extension).
// declaring the class name
class Exception
{
// main method ,and commad line arguments storage in string class.
public static void main(String args[])
{
// variables declaration
int a,b, ans;
try
{
// passing value in interger value from command line argument and storage variable a
a=Integer.parseInt(args[0]);
// passing value in interger value from command line argument and storage variable b
b=Integer.parseInt(args[1]);
try
{
//arithmentic operations and calculations store value in the ans variable.
ans = a/b;
System.out.println(" Anser Is :"+ans); // display value of ans variable.
}
catch(ArithmeticException e) // if any exception in arithmeticException than passing this catch block.
{
System.out.println(" Divided by Zero"); // display message of exception of arithmetic exception.
}
}
catch(NumberFormatException e) // if any exception of invalid of inpur value than passing this catch block.
{
System.out.println(" Invalid value entered"); // display message of invalid value entered.
}
}
}
above programe output as below can from different type of value entered with arithmetic and invalid value.
here we have seen simple programe using nested try-catch blocks.
exception handing use when errors come to run time when input value and any logical error generates that time programe terminates and close and not execution next statement, using exception handling we can pass errors and run all statements in programs.
If you get this, then share with your friends. And if you have query, contact-me and give comment

Exception Handling
Always, A Program doesn't run easly during its lifetime. Sometimes need to be handling unexpected errors in programs. many times user entered invalid inputs , networks connection drops, database fetching down and storage full, etc. such case as are referred as exception. which are programing stop execution normally.As programmers we should handle these cases in order to present user interactions with users and let the program continues normally, instead of leaving programing crashed or die, its called "EXCEPTION HANDLING".

JAVA PERMISSION CLASSES !
The Java programming language is a state-of-the-art, object-oriented language that has a syntax similar to that of C.
The Java platform is just as important as the Java programming language and the Java Virtual Machine. All programs written in the Java language rely on the set of predefined classes.
Some important Permission classes by the core Java platform and summarizes the permissions they represent.
Here Below Table about Permission classes and there Descriptions showing.
Permission
class
|
Description
|
java.security.AllPermission
|
An instance of this special
permission class implies all other permissions.
|
javax.sound.sampled.AudioPermission
|
Controls the ability to play and
record sound.
|
javax.security.auth.AuthPermission
|
Controls access to authentication
methods in javax.security.auth and its subpackages.
|
java.awt.AWTPermission
|
Controls access to sensitive
methods in java.awt and its subpackages.
|

Governs access to system
properties.
|

|
Governs access through the java.lang.reflect package to classes and class members that would normally
be inaccessible.
|
java.lang.RuntimePermission
|
Governs access to a number of
methods and resources. Many of the controlled methods are defined by java.lang.System and java.lang.Runtime.
|

The classes of the Java platform are collected into related groups, known as
packages. Most programs manipulate text in one form or another, and the Java platform
defines a number of important classes and interfaces for representing,
formatting, and scanning text.
In the table There Some Classes Display. there is more available to use of security enhancement. Jave Permission Classes need to security of clients and users to data protection.

FACEBOOK STORED MILLIONS OF USERS PASSWORD IN PLAIN TEXT.
Millions of Facebook user account password stored in plaintext and easy searchable by thousands of Facebook employees.
where Facebook is probing a series of security failures in which employees built applications that singed unsecured password data for Facebook users and stored internal company server in plaintext.
Here is discovering bugs out from the Facebook there is uses hundreds millions of users account password where searchable stored in Facebook internal server where thousand Facebook employees finding them, and it's bugs from internal investigating and primary reported by KOS.
Facebook said that it hashes and encrypts passwords, but it's how done of hundreds of millions of accounts password in plain text in internal company server stored.
where twitter given advised of millions users to change their password, after big bugs discovering password stored in plain text.
Facebook said "in security terms, we 'hash' and 'salt' the passwords, with using a function called "scrypt" as well as a cryptographic key that lets us irreversibly replace your actual password with a random set of characters,".
We Advised : "Be Secure and Be Careful."
