Java Static Initializer Block

  • utpal_kumar74 + 3 comments

    why so many comparison operator dude. Simply below would work just fine.

    static boolean flag = true; static int B, H; static Scanner sc = new Scanner(System.in);

    static { B = sc.nextInt(); H = sc.nextInt();

    if (B <= 0 || H <= 0) {
    flag = false;
    System.out.println("java.lang.Exception: Breadth and height must be positive");

      What if B and H are Both 0?

      Better be B<0 || H<0.

        If both are 0, there should be an Exception, it's written in the task:

        1. if both values are greater than zero => output the area
        2. otherwise => java.lang.Exception

      it doesn't works fine. it gives some expression error bcoj u use static keyword before Scanner class.....

      This works

      static int B,H; static boolean flag=true; static Scanner sc=new Scanner(System.in); static{ B=sc.nextInt(); sc.nextLine(); H=sc.nextInt(); sc.close(); if((B>=0&&H>=0)&&(B!=0&&B!=100)&&(H!=0&&H!=100)){ flag=true; }else{ flag=false; System.out.println("java.lang.Exception: Breadth and height must be positive"); }

        why did we keep the whole loop in a static block

        • jayeshchoudhary1 + 1 comment

          it doesn't matter

          • prasannareddy351 + 0 comments

            if not, it is throwing an error
