帮我看下这个代码 编译提示需要'{' 本人菜鸟 望高手解答
public abstract class Student {
private String name;
private String no;
public abstract void printlnfo() {

}
public Student() {
no="20100701020xx";
name="lx";
}
public static void print() {
System.out.println("name:" +name);
System.out.println("no:" +no);
}
}

public class MaleStudent extents Student {
private String gender;
public MaleStudent(String gender) {
this.gender=gender;
}
public static void printlnfo() {
System.out.println("name:"+name);
System.out.println("no:+no");
System.out.println("gender:+gender");
}
public static void main(String[] args) {
MaleStudent m=new MaleStudent();
printlnfo();
}
}

[解决办法]
有很多地方需要改动，代码贴到下面你自己找一下问题吧，看你语法还是很生疏，找本教材学习下

Java code

abstract class Student {    private String name;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getNo() {        return no;    }    public void setNo(String no) {        this.no = no;    }    private String no;    public abstract void printlnfo();    public Student() {        no="20100701020xx";        name="lx";    }    public void print() {        System.out.println("name:" +this.getName());        System.out.println("no:" +no);    }}public class MaleStudent extends Student {    private String gender;    public MaleStudent(String gender) {        super();        this.gender=gender;    }    @Override    public void printlnfo() {        System.out.println("name:"+this.getName());        System.out.println("no:+no");        System.out.println("gender:+gender");    }    public static void main(String[] args) {        MaleStudent m=new MaleStudent("man");        m.printlnfo();    }}
