public class test1 {
    public static void main(String[] args) {
        javabean1.teachername="jianjun";//直接在类调用，方便一点点
        javabean1 s1 = new javabean1();
        s1.setName("liujiawei");
        s1.setAge(18);
        s1.setGender("男");
        s1.study();
        s1.show();
        System.out.println();
        javabean1 s2=new javabean1();
        s2.setName("fanwenshuo");
        s2.setAge(18);
        s2.setGender("女");
        s2.study();
        s2.show();
