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.

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;
                  }
                break;
     }    
  }

                }
              break;  
         }

    }
}
Q) WAP  to check entered char is numeric, alphabets, or special using switch?

   {
        char ch;
       
        Scanner sc = new Scanner(System.in);

         Object o=ch>=48 && ch<=57;
         Object o1 = ch>=65 && ch<=91 || ch>=97 && ch<=123;
         switch(o.toString())
        {
           case "true":
