public class Student()
{

private long id;
private StringBuilder name;
private int age;
public long getId() {
return id;
}
//set方法
public void setId(long id) {
this.id = id;
}

public StringBuilder getName() {
return name;
}

public void setName(StringBuilder name) {
this.name = name;
}
//get的方法
public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}
//无参构造
public Student(){

}
}

这种编程以秒为单位ko它
Student student = new Student（）；
student.setAge(18);
student.setId(1);
student.setName(new StringBuilder("zhangsan"));

完善代码
package myWorld;

public class Student {

private long id;
private StringBuilder name;
private int age;
public long getId() {
return id;
}
//set方法
public void setId(long id) {
this.id = id;
}

public StringBuilder getName() {
return name;
}

public void setName(StringBuilder name) {
this.name = name;
}
//get的方法
public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}
public static void main(String args[])
{
Student func = new Student();
func.setAge(18);
func.setId(1);
func.setName(new StringBuilder("zhangsan"));
System.out.println(func.getAge()+".."+func.getId()+".."+func.getName().toString());
}

}
