Switch Statement in Java

Switch Statement in Java:-
1) Switch Statement
It is used to solve option based program.it provides multiple options using multiple case statements.
If we want to develop a choice based program then we mostly prefer switch statements in Java.
Syntax of Switch:-
switch(option)
{
   case optionvalue:
     statement;
     break;
  ....
  default:
   statement:
   break;
}
at runtime option==optionvalue  then that statement will be executed.
/* WAP to choose social media platform according to initial char? *                                                                                                                              
import java.util.Scanner;
class Socialmedia
{
    public static void main(String args[])
    {
      char ch;
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter you choice of social media to enter initial char");
      ch = sc.next().charAt(0);
      switch(ch)    // ch=='f'
      {
           case 'f':
           case 'F':
           System.out.println("You have choosen Facebook");
           break;
           case 'i':
           case 'I':
           System.out.println("You have choosen Instagram");
           break;
           case 't':
           case 'T':
           System.out.println("You have choosen Twitter");
           break;
           case 'w':
           case 'W':
           System.out.println("You have choosen Whatsapp");
           break;
           default:
           System.out.println("Wrong option");
           break; 
      }   
     } 
}
Q) WAP to check vowel and consonant using a switch?
import java.util.Scanner;
class CheckVC
{
   public static void main(String args[])
   {
     Scanner sc = new Scanner(System.in);
     System.out.println("enter char");
     char ch=sc.next().charAt(0);
     switch(ch)
     {
              case 'a':
              case 'A':
              case 'e':
              case 'E':
              case 'i':
              case 'I':
              case 'o':
              case 'O':
              case 'u':
              case 'U':
              System.out.println("Vowel");
              break;
              default:
              System.out.println("Consonent");
              break; 
     }
  }
}

WAP to check even|odd using switch?
int num=5;
switch(num%2)
{
   case 0:
   System.out.
println("even");
   break;
   default:
   System.out.println("odd");
   break;
}
WAP to check the greater number using Switch?
class Greaterswitch
{
    public static void main(String args[])
    {
         int a=10,b=20;
         switch(a/b)
         {
             case 0:
             System.out.println("b is greater");
             break;
             default:
             System.out.println("a is greater");
             break; 
             }
         }
}.........................................................................................................
2) Nested Switch Statement:-
We can write more than one switch statement using the nested sequence in Java.Nested Switch Statement:-
switch(option)
{
    case optionvalue:
       switch(option)
       {
             case optionvalue:
                    Statement;
                     break;
            default:
                 Statement;
                 break;   
        }
   break;
  default:
     switch(option)
   {
         case optionvalue:
            statement;
             break;
        default:
             statement;
             break;
    }
 break;
}
}
WAP to check divisibility that number is divisible by 3 and 5 both?
import java.util.Scanner;
class CheckVC
{
   public static void main(String args[])
   {
      int num=3;
      switch(num%3)
      {
                case 0:
                 switch(num%5)
                  {
                       case 0:
                        System.out.println("divisible by both");
                        break;
                       default:
                       System.out.println("only divisible by 3");
                       break;
                  }
                 break;
               default:
                  switch(num%5)
                  {
                       case 0:
                        System.out.println("divisible by five");
                        break;
                       default:
                       System.out.println("not divisible by any");
                       break;

    The solution to this program:-
    class Greater
    {
    public static void main(String args[])
    {
    int a=20,b=100;
    switch(a/b)
    {
    case 0:
    System.out.println("b is greater");
    break;
    default:
    System.out.println("a is greater");
    break;

Uncontrolled form input in React-JS

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...

JSP Page design using Internal CSS

  JSP is used to design the user interface of an application, CSS is used to provide set of properties. Jsp provide proper page template to create user interface of dynamic web application. We can write CSS using three different ways 1)  inline CSS:-   we will write CSS tag under HTML elements <div style="width:200px; height:100px; background-color:green;"></div> 2)  Internal CSS:-  we will write CSS under <style> block. <style type="text/css"> #abc { width:200px;  height:100px;  background-color:green; } </style> <div id="abc"></div> 3) External CSS:-  we will write CSS to create a separate file and link it into HTML Web pages. create a separate file and named it style.css #abc { width:200px;  height:100px;  background-color:green; } go into Jsp page and link style.css <link href="style.css"  type="text/css" rel="stylesheet"   /> <div id="abc"> </div> Exam...

JDBC contain four different type of approach to communicate with Database Type 1:- JDBC-ODBC Driver Type2:- JDBC Vendor specific Type3 :- JDBC Network Specific Type4:- JDBC Client-Server based Driver  or JAVA thin driver:- Mostly we prefer Type 4 type of Driver to communicate with database server. Step for JDBC:- 1  Create Database using MYSQL ,ORACLE ,MS-SQL or any other database 2   Create Table using database server 3   Create Form according to database table 4  Submit Form and get form data into servlet 5  write JDBC Code:-     5.1)   import package    import java.sql.*     5.2)  Add JDBC Driver according to database ide tools     5.3)  call driver in program         ...
