public class Demo 
{
    public static void main(String[] args) 
    {
       int a=10,b=20;
       short c = (a<b)?a:b;
       System.out.println(c);
    }
}

这是我的程序,我得到以下错误,为什么我没有得到

"Demo.java:6: error: incompatible types: possible lossy conversion from int to short
short c = (a<b)?a:b;
1 error" 

我用变量声明写"final",它工作正常.但为什么会这样呢？

public class Demo 
{
    public static void main(String[] args) 
    {
        final int a=10,b=20;
        short c = (a<b)?a:b;
        System.out.println(c);
    }
}
