6.2 考虑一个表示图形的类，写出类中的属性及方法。
package book;
class Graph {
private float length;
private float width;
private String backcolor;
public float getLength() {
return length;
}
public void setLength(float length) {
this.length = length;
}
public float getWidth() {
return width;
}
public void setWidth(float width) {
this.width = width;
}
public String getBackcolor() {
return backcolor;
}
public void setBackcolor(String backcolor) {
this.backcolor = backcolor;
}
public void size() {
System.out.println("设置图片的尺寸");
}
public void color() {
System.out.println("设置图片的背景颜色");
}
}
public class JiOu {
public static void main(String[] args) {
Graph graph = new Graph();
graph.size();
graph.color();
}
}
运行结果:
设置图片的尺寸
设置图片的背景颜色
