我正在做一个个人项目,同时试验它.我在3个文件中包含3个类:Calculate.java,Geometry.java和Test.java.
到目前为止,Geometry.java只包含一些我想要使用的变量,get/set方法以及构造函数方法.
package project;
public class Geometry {
public static double length, width;
public Geometry() {
this.setLength(20);
this.setWidth(30);
}
public void setLength(double length){
this.length = length;
}
public void setWidth(double width){
this.width = width;
}
public double getLength(){
return this.length;
}
public double getWidth(){
return this.width;
}
}
Calculate.java有一个Geometry类型的公共变量,以及一个处理我在Geometry.java中创建的变量的方法.
package project;
import project.Geometry;
public class Calculate {
public static Geometry figure = new Geometry();
public static double area;
public void calcArea(){
this.area = figure.getLength() * figure.getWidth();
}
public double getArea(){ …
