2.switch statement with ranges in JAVA

Lets get started

If the value of a case label falls within a case range that has already been used in the switch statement, the compiler rejects the code with an error message.

syntax :

            case 0...4;   // error
            case 5 ... 9; // ok
        

Elaborate with a simple example :

 
        

/* Now we will see the same example which we 
taken in the if else statements blog  
but here we test is done for only 10 marks  
if marks are 10 - very good 
                9 - good 
                8 -  nice 
                7 - better luck next time  
                6 - poor study hard 
        0 to 5 - stay here one more year

import java.util.* ; 
public class MINtech{ 
    public static void main(String args[]){ 
        // calling the scanner class 
        Scanner sc = new Scanner(System.in); 
        System.out.println("Enter your Maerks(0-10) : ") ; 
        // taking int as a input  
        int marks = sc.nextInt(); 
     
        // Initializing switch condition 
        switch(marks){ 
            // checking whether the num is equals to 0 or 1 or 2 or 
			//3 or 4 or 5  or not  
            case 0 : 
            case 1 : 
            case 2 :  
            case 3 : 
            case 4:  
             
            case 5 : 
                System.out.println("Fail : stay here one more year "); 
                break ; 
            case 6 :  
                System.out.println("Poor - Study hard"); 
                break; 
                case 7 : 
                System.out.println("Better luck next time "); 
                break ; 
            case 8 :  
                System.out.println("Nice"); 
                break; 
                case 9 : 
                System.out.println("Good"); 
                break ; 
            case 10 :  
                System.out.println("Very Good"); 
                break; 
            // default will executed if num is not matched with 
            // the anyone of the above mentioned cases  
            default: 
            System.out.println("Inavalid marks"); 
            break ; 
        } 
    } 
} 

Output

        Enter your Maerks(0-10) : 
        5
        Fail : stay here one more year
    
        Enter your Maerks(0-10) : 
        10
        Very Good

        Enter your Maerks(0-10) : 
        56
        Inavalid marks
