这个Room类用JAVA怎么解呀

定义一个 Room 类，包含成员变量面积和高度，以及内部类 Table 和 Chair , Table 和 Chair 皆包含成员变量长、宽、高以及颜色。现将一张长宽高分别为100cm,100cm,80cm的白色桌子以及一把长宽高分别为40cm,30cm,50cm的黑色椅子放进个面积为60平米，高度为4米的房间。编程打印房间、桌子、椅子的信息。

如有帮助望采纳

public class Room {
   static Double mianji=60d;
    static Double gaodu=4D;
    
    public static void main(String[] args) {
        Table table=new Table();
        Chair chair=new Chair();
        System.out.println(mianji);
        System.out.println(gaodu);
        System.out.println(table);
        System.out.println(chair);
    }
    
    private static class Table {
        String color="白色";
        Double height=100D;
        Double weight=100D;
        Double length=80D;
    
        @Override
        public String toString() {
            return "Table{" +
