类型开头非法（其他）

Question

我正在为我的 CS 110 课程做一个实验，有一行代码无法编译。我确保它与参考材料上的模板相匹配。我不确定重现该问题需要多少代码，因此我提供了所有代码并 //ed 出现问题的位置。更具体地说，它位于第 42 行。错误显示“错误：类型非法开始”。我已经尝试删除一些我认为多余的括号，但弹出了更多错误。/* Author: Collin Walsh   Date: 10/15/2019   File name: NstedIfs.java*/import java.util.Scanner;public class NestedIfs {    //main    public static void main(String[] args) {        Scanner keyboard = new Scanner (System.in);        double outsideTempF;        System.out.println("What is the temperature outside?

Answer 1

本来应该是这样的：

/* Author: Collin Walsh

*/

import java.util.Scanner;

public class NestedIfs {

    // main

    public static void main(String[] args) {

        Scanner keyboard = new Scanner(System.in);

        double outsideTempF;

        System.out.println("What is the temperature outside? Input a value and press enter ");

        outsideTempF = keyboard.nextDouble();

        Scanner input = new Scanner(System.in);

        int raining = 0;

        System.out.println("If it is raining, enter the number 1. Then press enter");

        raining = keyboard.nextInt();

        // indicate what clothing to wear, based on temp

        if (outsideTempF > 70) {

            if (raining == 1) {

                System.out.println("Wear t-shirt, shorts, sandals, and an unbrella");

            } else {

                System.out.println("Wear t-shirt, shorts, and sandals.");

            }

        } else if (outsideTempF <= 30) {

            if (raining == 1) {

                System.out.println("Wear boots, pants, raincoat, and gloves.");

            } else {

                // for any temperature beolow 30

                System.out.println("Wear boots, pants, sweater, and gloves.");

            }

        } else {

            if (raining == 1) {

                System.out.println("Wear long-sleeve shirt, pants, a raincoat, and shoes");

            } else {

                System.out.println("Wear long-sleeve shirt, pants, and shoes");

            }

        }

    }

}

其中一个牙套有问题，其中一个System.out.println缺少一个点，所以它是System.outprintln
