Switch statement in Java programming Hands on Coding

 Switch statement in Java;

 In this section we are going to discuss about switch statement in Java.

• Switch statement allows us to execute one statement from many statement and the statements are termed as case.
• Inside the body of switch there will be many number of cases and there is a single number is passed at the place of parameter to select and execute the case.

Syntax;

• In the switch statement a value/number is passed in the place of parameter and the case from which the parameter is matched is executed.
• If none of the case is matched with parameter then default case will be executed.

Example 1:

class Easy   
 {   
  public static void main(String[] args)   
  {   
   int day=2;   
   switch(day)   
   {   
    case 1:   
        System.out.println("Monday");   
        break;   
    case 2:   
        System.out.println("Tuesday");   
        break;   
    case 3:   
        System.out.println("Wednesday");    
        break;   
    case 4:   
        System.out.println("Thrusday");   
        break;   
    case 5:   
       System.out.println("Friday");   
       break;   
    case 6:   
       System.out.println("Saturday");   
       break;   
    case 7:   
       System.out.println("Sunday");   
       break;   
    default:   
      System.out.println("No case matched");   
    }   
  }   
 }   
  / ### Output ###   
  Tuesday because day is equal to 2 and it matches with case 2 so the output is Tuesday   

Example 2: Check given Alphabet is vowel or consonant.

 import java.util.Scanner;   
 class Easy   
 {   
   public static void main(String[] args)   
   {   
    Scanner in=new Scanner(System.in);   
    char ch;   
    System.out.println("Enter any alphabet");   
    ch=in.next().charAt(0);   
    switch(ch)   
    {   
     case 'a':   
     case 'e':   
     case 'i':   
     case 'o':   
     case 'u':   
       System.out.println("Vowel");   
       break;   
     default:   
       System.out.println("Consonant");   
     }   
   }   
 }   
 / ### Output ###   
 Enter any alphabet m. Consonant /
