错误:找不到或加载主类(netbeans和java) [英] Error: Could not find or load main class (netbeans and java)

问题描述

我是Java的新手，但是有一定的编程经验.我正在读一本关于如何用Java语言编程的书.我对NetBeans和Java的了解不足，阻碍了我的进步.我的特殊问题是我的输出框中没有看到正确的输出. 不管代码如何.

I am new to Java, but have some programming experience. I am reading a book on how to program in the Java language. My progress is impeded by my lack of knowledge with NetBeans and Java. My particular problem is that I am not seeing proper output in my output box. Regardless of the code.

这里是一个例子.我确定我遗漏了一个小细节:

Here is an example. I am sure I am missing a minor detail:

public class Weather
{
    public static void main(String[] arguments)
    {
        float fah = 86;
        System.out.println(fah + " degrees Fahrenheit is ...");
        //To conver fahrenheit to Celsius
        //Begin by subtracting 32
        fah = fah - 32;
        //divide the answer by 9
        fah = fah / 9;
        //multiply that answer by 5
        fah = fah * 5;
        System.out.println(fah + "degree Celsius is ...");

        float cel = 32;
        System.out.println(cel + "degress Celsius is ...");
        //To convert Farhenheit to celsius
        //begin by multiplying 9
        cel = cel * 9;
        //divide answer by 5
        cel =cel / 5;
        //add 32 to the answer
        cel = cel + 32;
        System.out.println(cel + "degrees Farenheit");

        }
}

输出框:

run:
Error: Could not find or load main class weather.Weather
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)

推荐答案

关闭netbeans，然后删除此目录C:\ Users \您的名称此处\ AppData \ Local \ NetBeans \ Cache

Close netbeans and then delete this directory C:\Users\Your name here\AppData\Local\NetBeans\Cache

再次启动Netbeans，并让其读取项目.

Start Netbeans again and let it read the project.

测试项目.运行项目.它应该可以正常工作.

Test project. Run project. It should work fine.
