此处不允许使用“void"类型 (java) 错误 [英] 'void' type not allowed here (java) error

问题描述

这是我的代码:

public void start()
{
  //If the gas tank and oil have more than nothing, and the transmission is in gear park, then the car can start
  if((gasTank.getGasLevel() > 0) && (engine.getOilLevel() > 0) && (transmission.gearPark()))
  {
    engine.startEngine();
    System.out.println("Engine is now on");
  }
  else
  {
    System.out.println("Please make sure your car is in proper gear, engine has oil and gas.");
  }
}

我不断收到 'void' type not allowed here 错误.我不想返回任何东西，所以我知道我不需要 int、Boolean、double 等.

I keep getting 'void' type not allowed here error. I am not trying to return anything so I know I don't need int, Boolean, double, etc.

我做错了什么?

推荐答案

您的代码不在类中.

试试这个:

public class SomeClass {
    // your method here
}
