8.5java first lesson record post

Novice java entry.
Now that you are learning java, the first warm-up is the nine-nine multiplication table, as follows:

The second warm-up is to judge whether Xiaohua is an animal.

public class test1 {
    public static void main(String[] args){
        an xiaohua=new an();
        xiaohua.legs=2;
        xiaohua.say=false;
        if(xiaohua.legs ==4 && !xiaohua.say ){
            System.out.println("xiaohua是小狗"); }
        else {
            System.out.println("不是小狗");
        }
    }
}
