如果在Java中,则不是语句错误

Question

class Box
{
// Instance Variables
double length ,ipsos ;
double width ,mikos ;
double height ,platos;
// Constructors
 public Box ( double side )
{
width = side ;
height = side ;
length = side ;
}
public Box ( double x , double y , double z)
{
    platos = y ;
ipsos = z;
mikos = x ;

}

// Methods
double calculate(double praksi)
{
return 2 * ( width * height +
width * length +
height * length ) ;
}
double volume(double emvadon)
{
return platos*ipsos*mikos ;
}

@Override
public String toString() {
    return "Volume: " + volume(1) + "\n Calculate: " + calculate(1);
}
public class Cube extends Box {
    public Cube(double side) {
        super(side, side, side);
        if (side<0) { System.out,println("lathos timi);} 
    }
}

}

在上面的代码中,编译器在此找到错误:if(side <0){System.out,println("lathos timi);}

它说:不是声明

怎么了？我是java编程的新手,但现在关于来自C的'if'.

Answer 1

你的println语句中有一个逗号.它应该是:

System.out.println("lathos timi");
