下面程序输出是 public class Test { public static void m...
单项选择题下面程序输出是
public class Test {
public static void main(String args[]) {
double radius = 9.0;
Circle c = new Circle(radius);
setZero(c, radius);
System.out.println(c.radius);
System.out.println(radius);
}
public static void setZero(Circle c, double radius) {
c.radius = 0; radius = 0;
}
}
class Circle {
double radius;
Circle(double newRadius) { radius = newRadius; }
}
A 0.09.0
B 0.00.0
C 9.09.0
