public int age;

public int NO;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public int getNO() {
return NO;
}

public void setNO(int nO) {
NO = nO;
}

public void sayMyName(){
System.out.println("我会叫" + name);
}
public void study(){
System.out.println("我正在学习JAVA");
}
}
