我需要帮助找出我的代码有什么问题

Question

我收到一些错误，说找不到符号

import javax.swing.JOptionPane;

public class ShippingSales
{
    public static void main (String [] args)

{
    int weight,  miles;
    String temp;
    double shippingcharge, rate;

    shippingcharge = miles * rate;
    miles = 500;

    temp = JOptionPane.showInputDialog("Enter the weight of the package");
    weight = Interger.parseInt(temp);

    if (weight <= 2)
    {
        JOptionPane.showMessageDialog(null, "Your total amount is " + shipppingcharge);
        rate = 1.10;
    }

    if (weight > 2 && weight<= 6 )
    {
        JOptionPane.showMessageDialog(null, "Your total amount is " + shipppingcharge);
        rate = 2.20;
    }

    if (weight > 6 && weight<= 10)
    {
        JOptionPane.showMessageDialog(null, "Your total amount is " + shipppingcharge);
        rate = 3.70;
    }

    if (weight > 10)
    {
        JOptionPane.showMessageDialog(null, "Your total amount is " + shipppingcharge);
        rate = 3.80;
    }

}


}

Answer 1

 Interger.parseInt(temp);

第二眼你能看到这条线路有什么问题吗？

提示：拼写。

此外，您多次在变量引用中拼错了“运费”。

Answer 2

你在所有showMessageDialogs中使用了三个“p”，但变量名为shippingcharge

你拼错了Integer错误，你使用了Interger
