In this tutorial, we are going to write a Java program to use the switch statement in Java Programming with practical program code and step-by-step full complete explanation.

Java program using switch case.

 
class SwitchDemo
{
    public static void main(String args[])
    {
        int marks = Integer.parseInt(args[0]); 
        //take marks as command line argument.

        switch(marks/10)
        {
            case 10:
            case 9:
            case 8:
                System.out.println("Excellent");
                break;

            case 7:
                System.out.println("Very Good");
                break;
            
            case 6:
                System.out.println("Good");
                break;

            case 5:
                System.out.println("Work Hard");
                break;
            
            case 4:
                System.out.println("Poor");
                break;
            
            case 3:
            case 2:
            case 1:
            case 0:
                System.out.println("Very Poor");
                break;
            
            default:
                System.out.println("Invalid value Entered");
        }
    }
}

Output
