定义Shape抽象类，包含私有属性color，创建构造器为color赋值；包含计算周长的方法celPerimeter();定义子类Triangle，包含三边；定义子类Circle，包含半径radius；子类分别实现父类的计算周长功能。代码及运行结果

我了解了您的要求，以下是实现您需求的代码及运行结果：

// Shape抽象类
public abstract class Shape {
    private String color;

    public Shape(String color) {
        this.color = color;
    }

    public abstract double calcPerimeter();
}

// Triangle子类
public class Triangle extends Shape {
    private double a;
    private double b;
    private double c;

    public Triangle(String color, double a, double b, double c) {
        super(color);
        this.a = a;
        this.b = b;
        this.c = c;
    }

    @Override
    public double calcPerimeter() {
        return a + b + c;
    }
}

// Circle子类
public class Circle extends Shape {
    private double radius;

    public Circle(String color, double radius) {
        super(color);
        this.radius = radius;
    }

    @Override
    public double calcPerimeter() {
        return 2 * Math.PI * radius;
    }
}

public class Test {
    public static void main(String[] args) {
        Triangle t = new Triangle("红色", 3, 4, 5);
        System.out.println("三角形的周长为：" + t.calcPerimeter());

        Circle c = new Circle("蓝色", 5);
        System.out.println("圆形的周长为：" + c.calcPerimeter());
    }
}

运行结果：

三角形的周长为：12.0
圆形的周长为：31.41592653589793
