What is the difference between try-catch and throw?tccicomputercoaching.com

 

An exception is an event that occurs during the execution of programs. ... Throw keyword is used to explicitly throw an exception. Generally, throw keyword is used to throw user defined exceptions.

Exception handling is built upon three keywords: try, catch, and throw.

In simple Way try is used for RISKY CODE where a programmes can think that There may be a chance Of occurring Exception then Programmer will use try block and if there is any Exception occurs like (Division /O) then it will Throw that exception to CATCH block and Catch is use to verify exception type and Handle It. #Every try must have at least 1 Catch or finally or Both.. #Throws block never handle any exception It only Delegate the Exception to Main method or Caller method..

Try - Catch: Syntax

try
{
//Protected code
}catch(ExceptionName e1)
{
//Catch block
}

The throw keyword will allow you to throw an exception (which will break the execution flow and can be caught in a catch block). The throws keyword in the method prototype is used to specify that your method might throw exceptions of the specified type.

Throw: Syntax

public class TestThrow1{ 

   static void validate(int age){ 

     if(age<18) 

      throw new ArithmeticException("not valid"); 

     else 

      System.out.println("welcome to vote"); 

   } 

   public static void main(String args[]){ 

      validate(21); 

      System.out.println("rest of the code..."); 

  }

Social Media Marketing Service in Ahmedabad – tccicomputercoaching.com

 

Social media itself is a catch-all term for sites that may provide radically different social actions. For instance, Twitter is a social site designed to let people share short messages or “updates” with others. Facebook, in contrast is a full-blown social networking site that allows for sharing updates, photos, joining events and a variety of other activities.

Social media marketing is the use of social media to market a product or service. Companies address several stakeholders through social media marketing including (potential) customers, (potential) employees, journalists, bloggers and the general public. On a strategic level, social media marketing includes the management of the implementation, governance, scope (e.g. more active or passive use) and the establishment of a firm’s desired social media culture. This requires marketers to incorporate user-generated content into their strategic approach.



Social media can also help build links that in turn support into SEO Services efforts. Many people also perform searches at social media sites to find social media content. Social connections may also impact the relevancy of some search results, either within a social media network or at a ‘mainstream’ search engine.

 

Social networking websites allow individuals and businesses to interact with one another and build relationships and communities online. When companies join these social channels, consumers can interact with them directly. That interaction can be more personal to users than traditional methods of outbound marketing and advertising.

Social networking sites act as word of mouth or more accurately, e-word of mouth. The Internet’s ability to reach billions across the globe has given digital word of mouth a powerful voice and far reach. The ability to rapidly change buying patterns and product or service acquisition and activity to a growing number of consumers is defined as an influence network.

Social networking sites and blogs allow followers to “retweet” or “repost” comments made by others about a product being promoted, which occurs quite frequently on some social media sites. By repeating the message, the user’s connections are able to see the message, therefore reaching more people. Because the information about the product is being put out there and is getting repeated, more traffic is brought to the product/company.

Social Media contains Facebook, Twitter, Google Plus, Pinterest, LinkedIn etc… are very popular social sites, and Most of the people use them regularly. Facebook, in contrast is a full-blown social networking site that allows for sharing updates, photos, joining events and a variety of other activities.

Online Compiler Design Course in Ahmedabad - tccicomputercoaching.com

 

What is Compiler Design?

A compiler translates the code written in one language to some other language without changing the meaning of the program. It is also expected that a compiler should make the target code efficient and optimized in terms of time and space.

A compiler acts as a translator, transforming human-oriented programming languages into computer-oriented machine languages.

Programming                                                                                    Machine

Language                                           Compiler                                Language

(Source)                                                                                             (Target)

Any compiler must perform two major tasks

Compiler

·         Analysis of the source program

·         Synthesis of a machine-language program



Compiler Phases:

The compilation process is a sequence of various phases. Each phase takes input from its previous stage, has its own representation of source program, and feeds its output to the next phase of the compiler. Let us understand the phases of a compiler.

Lexical analysis:

Lexical analysis is the first phase of a compiler. It takes the modified source code from language pre-processors that are written in the form of sentences. The lexical analyzer breaks these syntaxes into a series of tokens, by removing any whitespace or comments in the source code.

A programming language must include the specification of syntax (structure) and semantics (meaning).

Syntax typically means the context-free syntax because of the almost universal use of context-free-grammar (CFGs)

Ex.

a = b + c is syntactically legal

b + c = a is illegal

Token:

The token name is an abstract symbol representing a kind of lexical unit, e.g., a particular keyword, or sequence of input characters denoting an identifier.

Syntax Analysis:

The next phase is called the syntax analysis or parsing. It takes the token produced by lexical analysis as input and generates a parse tree (or syntax tree). In this phase, token arrangements are checked against the source code grammar, i.e. the parser checks if the expression made by the tokens is syntactically correct.

Semantic Analysis:

Semantic analysis checks whether the parse tree constructed follows the rules of language. For example, assignment of values is between compatible data types, and adding string to an integer.

Intermediate Code Generation:

Interpreters are easier to write and can provide better error messages (symbol table is still available) Interpreters are at least 5 times slower than machine code generated by compilers Interpreters also require much more memory than machine code generated by compilers Examples: Perl, Python, Unix Shell, Java, BASIC, LISP

Code Optimization:

The next phase does code optimization of the intermediate code.

Code Generation:

In this phase, the code generator takes the optimized representation of the intermediate code and maps it to the target machine language.
