为什么double price=120.5f;过不了，而double price=120.5;过了
public class HelloWorld{
public static void main(String[] args) {
String name="爱慕课";
char sex='男';
int num=18;
double price=120.5;
boolean isOK=true;
System.out.println(""+name);
System.out.println(""+sex);
System.out.println(""+num);
System.out.println(""+price);
System.out.println(""+isOK);
}
}
