ID3决策树算法的JAVA实现：ID3算法是机器学习中的一种分类方法

package dsstree;
import java.util.Vector;
public class TreeNode
{
  private int attr;
  private TreeNode parent = null;
  private int parent_attr_value;
  private int num = 0;
  private Vector children = null;
  public TreeNode(int attr1, int pav) {
    attr = attr1;
    parent_attr_value = pav;
    children = new Vector(0, 5);
  }

  public int getattr() {
    return attr;
  }

  public int getchildrenNum() {
    num = children.size();
    return num;
  }

  public int getParent_attr_value() {
    return parent_attr_value;
  }

  public void addChild(TreeNode child) {
    children.add(child);
  }

  public void setParent(TreeNode parent1) {
    parent = parent1;
  }

  public TreeNode getParent() {
    return parent;
  }

  public Vector getChildren() {
    return children;
  }
