复制代码 代码如下:package com.vd.dsl;import static com.vd.dsl.graphbuilder.*;public class main...

复制代码 代码如下:

package com.vd.dsl;
import static com.vd.dsl.graphbuilder.*;
public class main {
 public static void main(string[] args) {
  graph().edge().from("a").to("b").weigth(20.0).edge().from("b").to("c").weigth(10.0).printgraph();
 }
}

复制代码 代码如下:

package com.vd.dsl;

public class edge {
 private vertex fromvertex;
 private vertex tovertex;
 public vertex getfromvertex() {
  return fromvertex;
 }
 public void setfromvertex(vertex fromvertex) {

  return weight;
 }
 public void setweight(double weight) {
  this.weight = weight;
 }

  return fromvertex.getlabel()+ " to "+
   tovertex.getlabel() + "with weigth "+
