what is the issue with my code?seems correct to me but not verifying

Question about the task

Under discussion

package com.codegym.task.task15.task1515; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; /* Static modifiers: part 2 */ public class Solution { public static int A; public static int B; static{ try{ BufferedReader b=new BufferedReader(new InputStreamReader(System.in)); System.out.println("enter number"); int A=Integer.parseInt(b.readLine()); System.out.println("enter number"); int B=Integer.parseInt(b.readLine()); } catch(IOException e){ } } public static final int MIN = min(A, B); public static void main(String[] args) { System.out.println(MIN); } public static int min(int a, int b) { return a < b ? a : b; } }

1. In a static block, read two int variables A and B from the console.
2. Don't forget about the IOException that must be handled in the catch block.
3. Close the input stream with the close() method.

Requirements:

Field A must be public and static.
Field B must be public and static.
The program should read data from the keyboard in a static block.
The program must initialize the fields A and B in a static block using the values entered from the keyboard.
The program should display the minimum of the values entered from the keyboard.

This task is quite strange and i don't see any value in it but this is how i managed to resolve it: 1. In the first part nothing changes form the original code

public class Solution {
    public static int A;
    public static int B;

    public static final int MIN = min(A,B);

2. Added the static block with try/catch

static {
        try {
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

            A = Integer.parseInt(br.readLine());

            B  = Integer.parseInt(br.readLine());

            br.close();

        } catch (IOException e) {
            e.printStackTrace();
        }

    }

3. Modified in the main in order to validate the "The program should display the minimum of the values entered from the keyboard." condition

public static void main(String[] args) {
       System.out.println(min(A,B));
   }

4. Modified the return of the minimum ( but this is not necessary )

public static int min(int a, int b) {
        return Math.min(a, b);
    }

I think you are never storing the input from reader in the correct variables. Inside the try block update the value of A and B calling "Solution.A" and "Solution.B", not "int A" - "int B". Those 'ints' create different variables, I would say. static { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); try { Solution.A = Integer.parseInt(reader.readLine()); Solution.B = Integer.parseInt(reader.readLine()); reader.close(); } catch (IOException e) { System.out.println(e); } }

try this code public class Test { public static int A; public static int B; public static int c; static{ try{ BufferedReader b=new BufferedReader(new InputStreamReader(System.in)); System.out.println("enter number"); int A=Integer.parseInt(b.readLine()); System.out.println("enter number"); int B=Integer.parseInt(b.readLine()); c = min(A,B); } catch(IOException e){ e.printStackTrace(); } } //public static final int MIN = min(A, B); public static void main(String[] args) { System.out.println(c); } public static int min(int a, int b) { return a < b ? a : b; } }

Try to change `int A` + `int B` in the static block to A = Integer.pars... B = Integer.pars...
