Your code will give compilation errors as we can't use curly brace after case : Exact code is:

public static void main(String... args){
        int a = 1;
        System.out.println("start");
        switch(a){
            case 1:
                System.out.println(1);
                case 3:
                    System.out.println(3);
                case 4:
                    System.out.println(4);

            case 2:
                System.out.println(2);
                case 5:
                    System.out.println(5);
                case 7:
                    System.out.println(7);
            }

        System.out.println("end");
    }
    }

and output will be start 1 3 4 2 5 7 end because you have not use "break" after each case.
