Java Static Initializer Block

  • pbhanuchandra + 4 comments

    You have a error in else if() block

    Here is the actual answer

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

        your program is correct but how i am not able to understand the logic behind this if ((B<0 && H<0)&&(B>=0&&H>=0)) suppose :we will give input 1and 3 then it shoud go to false block because B<0 && H<0 =false B>=0&& H>=0=True false && true false should come

      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

      what is the use of nextLine() bro

    • aniket_bharalla + 0 comments

      This one is the correct code you have written if block wrong. static int B,H; static boolean flag=true; static{ Scanner scan = new Scanner(System.in); B = scan.nextInt(); scan.nextLine(); H = scan.nextInt(); scan.close(); if(B>0 && H>0){ flag = true;

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