选择不包含主要类型 [英] Selection does not contain a main type

问题描述

当我将其作为Java应用程序运行时，它会显示警告选择不包含主类型".有人可以告诉我怎么了吗?并在错误不再出现后看起来会运行吗?

When I run this on as a Java application it comes up with the warning "Selection does not contain a main type". Can someone tell me what''s wrong? And does it look like it would run after the error no longer appears?

package com.ajaxwoot;

public class Camcorder {

	int recTime;
	boolean canRecord = true;

	public void record(){
		if (canRecord = true){
			System.out.println("I''m recording this now.");
		}
		recTime = 1;
		while (recTime < 20){
			System.out.println("In the process of recording. Time left: " + recTime++);
			
		}
	}
}

推荐答案

这是完整的代码吗?

然后，您缺少了main方法，该方法是您编码的入口点:

This is the complete code right?

Then you''re missing the main method, which is needed as the entry point to your coding:

public class Camcorder{
  public static void main(String[] args) {
    Camcorder oComcorder = new Camcorder();
    Camcorder.record();
  }

// rest of your code goes here
