利用Scanner和ArrayList完成的一个学生管理系统

package guiJia;
/*
 * 学生类
 */
public class Student {
	
	private String id;
	private String name;
	private String age;
	private String address;
	
	
	public Student() {
		
	}

	public Student(String id, String name, String age, String address) {
		this.id = id;
		this.name = name;
		this.age = age;
		this.address = address;
	}

	public String getId() {
		return id;
	}


	public void setId(String id) {
		this.id = id;
	}


	public String getName() {
		return name;
	}


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


	public String getAge() {
		return age;
	}


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


	public String getAddress() {
		return address;
	}


	public void setAddress(String address) {
		this.address = address;
	}	
}
