How to solve the problem and why does the compiler swear at the parameters?

Question

Java

There is a task:
You need to write a method that has three integer parameters and returns the maximum of them.

but the compiler swears at the parameters, why? What I've done:

package homeWorks;

import java.util.Arrays;
import java.util.Scanner;

class HW1 {
    public static void main(String[] args) {
        // методы в методе main должны иметь модификатор static
        



        public static int getValue(int a, int c, int b){
            Scanner sc = new Scanner(System.in);
            System.out.println("Enter the first value: ");
            a = sc.nextInt();

            System.out.println("Enter the second value: ");
            b = sc.nextInt();

            System.out.println("Enter the third value: ");
            c = sc.nextInt();

            int[] array = new int[3];
            array[0] = a;
            array[1] = a;
            array[2] = c;

            Arrays.sort(array);
            System.out.println("max value is " + array[2]);
        }




    }

}
