Answer 1

import java.util.Scanner;   // change lang to util

public class PositiveNegative {

    public static void main(String[] args) {    // add void here
        double number = 0;
        Scanner input = new Scanner(System.in); // use System instead of system
        System.out.print("Enter a number ==> ");
        number = input.nextDouble();    // end statement with ;
        if (number < 0)     // remove then here
            System.out.println("Negative ");
        else
            System.out.println("Positive");
    }// replace ) with }
}
