Question

各位电脑大神，求解！！！

因为iertutil.dll , urlmon.dll丢失，导致大多数软件不能使用，如QQ，音乐软件，360相关软件，求解决方案，要详细O(∩_∩)O哈！

Answer 1

package Circle;
/**
* 定义点类
* @author Sontion
*
*/
public class Point {
//X坐标和y坐标
private double x;
private double y;

//重写构造方法
public Point(double x, double y) {
this.x = x;
this.y = y;
}

//定义get/set方法
public double getX() {
return x;
}
public void setX(double x) {
this.x = x;
}
public double getY() {
return y;
}
public void setY(double y) {
this.y = y;
}

}

package Circle;

/**
* 编写圆类
* @author Sontion
*
*/
public class Circle {
private double r;
private Point point;

public Circle(double r, Point point) {
super();
this.r = r;
this.point = point;
}

/**周长*/
public double getLength(Circle c){
double length=0.0;
double pi=3.14;

length=2*pi*c.getR();

return length;
}

/**面积*/
public double getArea (Circle c){
double length=0.0;
double pi=3.14;

length=pi*c.getR()*c.getR();

return length;
}

public double getR() {
return r;
}
public void setR(double r) {
this.r = r;
}
public Point getPoint() {
return point;
}
public void setPoint(Point point) {
this.point = point;
}

}

package Circle;

public class test {
public static void main(String[] args) {
Point po = new Point(1.0,1.0);
Circle c = new Circle(4.0,po);
double a = c.getLength(c);
double b = c.getArea(c);
System.out.println(a+","+b);
}
}

写了个，可能我没明白你的意思，算周长用x,y干嘛？
这样可以么？

Answer 2

在别的机器考过来试一下，。不行就重做系统 吧

Answer 3

你把QQ发给我，我把安装包给你发过去安装一下就好了，望采纳！
