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。

下面是代码实现：

// Shape.java
public abstract class Shape {
    private String color;

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

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public abstract double calcPerimeter();
}

// Triangle.java
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;
    }

    public double getA() {
        return a;
    }

    public void setA(double a) {
        this.a = a;
    }

    public double getB() {
        return b;
    }

    public void setB(double b) {
        this.b = b;
    }

    public double getC() {
        return c;
    }

    public void setC(double c) {
        this.c = c;
    }

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

// Circle.java
public class Circle extends Shape {
    private double radius;

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

    public double getRadius() {
        return radius;
    }

    public void setRadius(double radius) {
        this.radius = radius;
    }

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

使用示例：

Triangle triangle = new Triangle("Red", 3, 4, 5);
System.out.println(triangle.getColor() + "三角形的周长为：" + triangle.calcPerimeter());

Circle circle = new Circle("Blue", 2.0);
System.out.println(circle.getColor() + "圆形的周长为：" + circle.calcPerimeter());
