If you people encounter with such error message Like 404,301 while browsing on internet then you should definitely know about http status code

This type of message called http status code there are numerous Http status code ranging from 100-500

Let's jump in to this

Table of content

✅Http status code

✅Classification

↘️Informational response (100–199)

↘️Successful response (200–299)

↘️Redirection message (300–399)

↘️Client error response (400–499)

↘️Server error response (500–599)

when ever client send a request to the server every time server response this request in the from of http status code

These are codes the server can generate in response to HTTP requests

HTTP status codes are three-digit codes, and are grouped into five different classes

1️⃣1xx (Informational response)

It means the request has been received and the process is continuing.

The informational response is classify as:

✅100 - Continue.

✅101 - Switching protocols.

2️⃣ 2xx (Success response )

It means the action was successfully received,understood,accepted.

The 2xx response is classify as:

✅200:The request is OK

✅201:The request has been created

✅202:The request has been accepted for processing, but the processing has not been completed
✅204 : The server successfully processed the request, and is not returning any content

3️⃣3xx (Redirection message)

It means further action must be taken in order to complete the request.

The 3xx is classify as:

✅301:The 301 status tells that the request has moved permanently to a new URL

✅302:The 302 HTTP status tell that requested page exists at different URL

4️⃣ 4xx (Client Error)

✅404:The content you are trying to looking for in a website is not present in server

5️⃣5xx (Server Error)

It means the server failed to fulfill thevalid request.

The 5xx is classify as:

✅500:The server is unable to fulfill the request due to an unexpected condition.

✅503:The server cannot handle the request because it has run out of resources
✅505 : The server doesn’t support the HTTP protocol version used in the request. Using an outdated web browser usually triggers this response code.

key takeaway

These status codes serve as a means of communication between the server and the internet browser
HTTP status codes are generated by the server that's hosting the site when it responds to a request made by a client

That's wrap up

In today's world internet is the basic need we use search engine and web browser for surfing on the internet to view content on the internet we use web browser and to access that content from the internet we use search engine many folks get confused between browser and search engine
Although search engine and web browser work together but there are difference in between them

Browser
✅Browser is the window to internet
✅Web browser allow you to retrive, read the content from the web page available on the web server and these web page found out with the help of search engine
✅A web browser allow you to see the searched content
Firefox , brave are example

Search engine
✅A search engine is used to find the information in the World Wide Web
✅We access search engine through browser
✅Search engine require database
✅Search engine allow you to find out particular content from the internet
Goggle, Bing , duckduckgo are some examples of search engine

In closing:
The content available on internet
✅ Is display to the users with the help of browser, In browser you enter the url
✅ Find out with the help of search enginen , In search engine you enter the key words or phrase

That's wrap up

Operators in Java

Brain CodeDesign — Wed, 28 Sep 2022 18:07:22 +0000

Basic stands everywhere so in programming too operators are the fundamentals of any programming language so in this blog I'll write about the operators in Java
So what basically operators are?
"Operators are used to perform operations on variables and values"

Arthmetic operator
int num1 = 10;

    int num2 = 20;
    System.out.println("the value of num1 + num2 is");
    System.out.println(num1 + num2);
    System.out.println("the value of num1 - num2 is");
    System.out.println(num1 - num2);
    System.out.println("the value of num1 * num2 is");
    System.out.println(num1 * num2);
    System.out.println("the value of num1 / num2 is");
    System.out.println(num1 / num2);
    System.out.println("the value of num1 % num2 is");
    System.out.println(num1 % num2);

Assignment operator
int num1 = 10;
int num2 = 20;
num2 = num1;

    System.out.println("= Output: "+num2);

    num2 += num1;

    System.out.println("+= Output: "+num2);
    num2 -= num1;
    System.out.println("-= Output: "+num2);
    num2 *= num1;
    System.out.println("*= Output: "+num2);
    num2 /= num1;
    System.out.println("/= Output: "+num2);
    num2 %= num1;
    System.out.println("%= Output: "+num2);

Logical operator
Int a=9;
Int b=11;
int c=20;

    System.out.println(a<b&a<c);
    System.out.println(a>b||a<c)
    System.out.println(a>b|a<c);
    System.out.println(a>b||a++<c);
    System.out.println(a);
    System.out.println(a>b|a++<c);
    System.out.println(a);

Comparison or rational operator
Int a=9;
Int b=11;
int c=20;

    System.out.println("a is "+  a + " and b is " + b);

    // == operator
    System.out.println(a == b);  // false

    // != operator
    System.out.println(a != b);  // true

    // > operator
    System.out.println(a > b);  // false

    // < operator
    System.out.println(a < b);  // true

    // >= operator
    System.out.println(a >= b);  // false

    // <= operator
    System.out.println(a <= b);  // true
