JAVA设计一个立方体类Cube，只有边长属性，具有设置边长，获取边长，计算表面积，计算体积的方法。创建Cube对象，为其设置新边长，显示其边长，计算并显示其表面积和体积。；

public class Cube {
    private double edgeLength;

    public void setEdgeLength(double edgeLength) {
        this.edgeLength = edgeLength;
    }

    public double getEdgeLength() {
        return edgeLength;
    }

    public double getSurfaceArea() {
        return 6 * edgeLength * edgeLength;
    }

    public double getVolume() {
        return edgeLength * edgeLength * edgeLength;
    }
}

public class Main {
    public static void main(String[] args) {
        Cube cube = new Cube();
        cube.setEdgeLength(5.0);
        System.out.println("Edge Length: " + cube.getEdgeLength());
        System.out.println("Surface Area: " + cube.getSurfaceArea());
        System.out.println("Volume: " + cube.getVolume());
    }
}
