Question

public static void main(String[] args)
 {
// declares variables
int items, time;
double heat, h1, h2, h3, h4;
h1 = 1.00;
h2 = 1.25;
h3 = 1.50;
h4 = 2.00;

  Scanner num  = new Scanner(System.in);

 // asks user to input the amount of items to heat and the amount of time to 
heat the items      
  System.out.println("Select number of items being heated");
  items = num.nextInt();
  System.out.println("Select amount of time in seconds to heat one item");
  time = num.nextInt();

    // gets user to re-enter the amount of items to less than 5  
    while (items > 4)
    {
            System.out.println("warning: more than four items is too hot! 
\nplease enter a number below 5");
        items = num.nextInt();
}
//heating calculations
    switch (items)
    {
case 1:
            heat = h1;
    break;
    case 2:
            heat = h2;
    break;

    case 3:

            heat = h3;
    break;
    case 4:
        heat = h4;
default:
    heat = 1;
        }

        // outputs the total time
        System.out.println("Time: " + time * heat * items + " seconds");

 }
 }

任何帮助都会是伟大的家伙！这是一个学校项目，它说＆＃34;加热＆＃34;尚未初始化

Answer 1

你必须在代码中修改3行：

1.你忘记评论热量项目
//加热物品

你忘了加热后加上引号！“
你忘记在单词之前添加加号和引号。你需要添加符号才能用两行写一个字符串：

System.out.println（“警告：超过四个项目太热了！”

                + "\nplease enter a number below 5");

有人可以帮助我为什么我的字符串不工作？
