java二叉树模板抽象化

Question

我有两个二叉树类，分别管理着不同的数据
class bt1{
//自身业务逻辑
String s;
public String getS(){
return "godness " + s;
}

//二叉树逻辑
bt1 left;
bt1 right;
bt1 parent;
public void setLeft(bt1 l){
    this.left = l;
        l.parent = this;
}
public bt1 getLeft(){
    return left;
}
public void setRight(bt1 r){
    this.right = r;
    right.parent = this;
}
public bt1 getRight(){
    return right;
}
public bt1 getParent(){
 return parent;
}

}

class bt2{
//自身业务逻辑
int i;
public void add(){
i++;
}

//二叉树逻辑
bt2 left;
bt2 right;
bt2 parent;
public void setLeft(bt2 l){
    this.left = l;
        l.parent = this;
}
public bt2 getLeft(){
    return left;
}
public void setRight(bt2 r){
    this.right = r;
    right.parent = this;
}
public bt2 getRight(){
    return right;
}
public bt2 getParent(){
 return parent;
}

}

有没有什么办法把两个类公共的二叉树逻辑部分提出来做为父类，两个类分别继承这个父类再只需实现自己的业务逻辑，就能达成原代码功能的？

试试java的“泛型”
