illegal start of expression if statements

Question

I'm not sure where the error in the if statement is, any help is appreciated.

import java.util.Scanner; public class Exercise4P94 {

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    int carNum;
    boolean chck;
    do {
        chck = true;
        System.out.println("Enter the Car Model Number: ");
        carNum = input.nextInt();

        if (carNum == 119 || carNum == 179 || carNum >== 189 && carNum <== 195 || carNum == 221 || carNum == 780){
            System.out.println("Your car is defective and must be repaired");
        } else if (!(carNum == 119 || carNum == 179 || carNum >= 189 && carNum <= 195 || carNum == 221 || carNum == 780)){
            System.out.println("Your car is not defective");
        } else {
            System.out.println("Please enter a valid car model number");
            chck = false;
        }
    } while (chck);
}

}

Answer 1

You don't need two equal signs after a greater/less than sign

 carNum >= 189 && carNum <= 195
