出现break outside switch or loop

大家好，我是一个在国外学习的留学生。由于没有编程的基础，所以遇到了这个问题不知道该怎么解决，这是第一次遇到，试了好久也还是不行，请知道我的错误是怎么回事的朋友受累帮我一下，谢谢。
以下是我出现错误的代码：
import java.util.Scanner;

public class averageTemperature
{
    public static void main(String[] args)
    {
        Scanner keyboard = new Scanner(System.in);

        int day;
        int month;
        int year;
        double maximumTemperature;
        double minimumTemperature;
        double averageTemperature ;      

        System.out.print("Type the day month year ");
        day = keyboard.nextInt();
        month = keyboard.nextInt();
        year = keyboard.nextInt();
        if (( year > 2010) |(year <=0))
        {
            System.out.println("I don't know about that year!");        
            break;
        }
        System.out.print("Please type the maximum temperature:");
        maximumTemperature = keyboard.nextInt();
        System.out.print("Please type the minimum temperature:");
        minimumTemperature = keyboard.nextInt();

        averageTemperature = (maximumTemperature + minimumTemperature)/2;
        System.out.println("The average temperature in " +day +"/" +month +"/" +year + "is " + averageTemperature);
    }
}

上面红色部分在编译的时候说：
javac averageTemperature.java
averageTemperature.java:23: break outside switch or loop
            break;

大家好心，帮帮我，谢谢大家了。

你没有用循环和switch，不要用break;
这里的break要改为return

支持楼上
if (( year > 2010) |(year <=0))  //修改下  if (( year > 2010) ||(year <=0))

break;  //修改-->return

maximumTemperature = keyboard.nextInt(); //修改--->maximumTemperature = keyboard.nextDouble();因你定义的是double型
minimumTemperature = keyboard.nextInt(); //修改-->minimumTemperature = keyboard.nextDouble();
