用java编写一个简单例子，题目如下

package test;

public class Student {

private String name;

private String id;

private String clazz;

private int age;

private String address;

/**

* sayHello方法

*/

public void sayHello() {

System.out.println("学号为" + this.id + "的同学的具体信息如下：");

System.out.println("姓名：" + this.name);

System.out.println("班级：" + this.clazz);

System.out.println("年龄：" + this.age);

System.out.println("家庭住址：" + this.address);

}

/**

* 测试方法

*

* @param args

*/

public static void main(String[] args) {

// 第一问

Student student = new Student();

student.setAddress("百度知道");

student.setAge(1);

student.setClazz("一班");

student.setId("071251000");

student.setName("lsy605604013");

student.sayHello();

// 第二问

Student studentNew = new Student();

studentNew.setAddress("搜搜知道");

studentNew.setAge(2);

studentNew.setClazz("二班");

studentNew.setId("071251001");

studentNew.setName("lady");

if (student.getAge() studentNew.getAge())

studentNew.sayHello();

else if (student.getAge() studentNew.getAge())

student.sayHello();

else

System.out.println("两人一样大");

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public String getClazz() {

return clazz;

}

public void setClazz(String clazz) {

this.clazz = clazz;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

}
