Why doesn't the first assignment work in an if?

Question

Java

There is a code

package code;

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        try (Scanner input = new Scanner(System.in)) {
            int a;
            int b;
            int c;
            int max;
            System.out.println("Iput A");
            a = input.nextInt();
            System.out.println("Iput B");
            b = input.nextInt();
            System.out.println("Iput C");
            c = input.nextInt();

            max = a;
            if (b > max) {
                max = b;
            }
            if (c > max) {
                max = c;
            }

            System.out.println("Max = " + max);
        }
    }
}

In principle, it is very clear, but I don’t understand why the program will not work if we allow the variable and also place it in if?

if(a > max) {
          max = a;
          }       

            if (b > max) {
                max = b;
            }
            if (c > max) {
                max = c;
            }

Why does the program give an error in this case?

Answer 1

And you carefully read the error - everything is written in it.
Well, or just think that in this case, println should output if none of the ifs worked.
