这里不允许'void'类型(java)错误

Question

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.");
  }
}

我一直在收到'void' type not allowed here错误.我不是想要返回任何东西所以我知道我不需要int,Boolean,double等.

我究竟做错了什么？

Answer 1

您的代码不在类中.

试试这个:

public class SomeClass {
    // your method here
}
