Java - 不编译错误

Question

我正在为商店做代码,这部分是为了让员工可以将手机添加到现有库存中.我无法弄清楚问题是什么,因为它不会编译并说"不兼容的类型",它标志着部分[name =""; type =""; color ="";]

这是驱动程序类的一部分:

      //add new phone to stock
public void addPhone( ) {

     Phone phone = new Phone ( itemsId, brand, price, name, type, colour);

    Scanner scan = new Scanner(System.in);
    String itemsId; 
    String brand;
    double price;
    String name;
    String type;
    String colour;


    for (int counter=0; counter< 1; counter ++)
    {
        itemsId= "  ";
        brand="     ";
        price= 
        name= "  ";
        type="  ";
        colour=" ";

        System.out.println("Enter itemsID:   ");
        itemsId= scan.nextLine();

        System.out.println("Enter brand:     ");
        brand= scan.nextLine();

        System.out.println("Enter price:     ");
        price= scan.nextdouble();

        System.out.println("Enter name:      ");
        name= scan.nextLine();

        System.out.println("Enter type:       ");
        type= scan.nextLine();

        System.out.println("Enter colour:     ");
        colour= scan.nextLine();

    }
    phoneList.add(phone);

}

Answer 1

您应该为其分配值price.

price = 0.0;
name = " ";

应该管用.
