这个是关于Java的问题。。

Cat类：

public class Cat {
    private String pz; //品种
    private String color; //颜色
    private String tx; //体型
    public Cat(String pz,String c,String tx){
        this.pz = pz;
        this.color = c;
        this.tx = tx;
    }
    public Cat(){}
    
    public void Jiao(){
        System.out.println("喵喵");
    }
    
    public void Run(){
        System.out.println("猫咪跑");
    }
    public String getPz() {
        return pz;
    }
    public void setPz(String pz) {
        this.pz = pz;
    }
    public String getColor() {
        return color;
    }
    public void setColor(String color) {
        this.color = color;
    }
    public String getTx() {
        return tx;
    }
    public void setTx(String tx) {
        this.tx = tx;
    }
    public void Jump(){
        System.out.println("跳跃");
    }
    

}

测试：

public static void main(String[] args){
        Cat ct = new Cat("波斯猫","白色","体型偏胖");
        ct.Jiao();
        ct.Run();
        ct.Jump();
    }

public class Cat {

    String kind; //品种
    String color; //颜色
    String tx;//体型
    public void speak() {
        System.out.println("猫猫叫");
    }
    public void run() {
        System.out.println("猫正在跑");
    }
    public void Jump() {
        System.out.println("猫正在跳。");
    }
}
