本文通过《编写可读代码的艺术》一书中的建议，介绍了如何使用列对齐来提高代码的可读性和组织性。以一个学生类为例，展示了通过列对齐变量声明和初始化可以使得代码更加整洁有序。

本文参考自《编写可读代码的艺术》，这本书写的非常好！

有时候，我们可以通过“列对齐"的方式，让代码更易读。实例代码如下：

package com.jue.test;

public class Student {

	// 一种有意义的排列顺序
	public final static int INDEX_ID			 = 0;
	public final static int INDEX_NAME			 = 1;
	public final static int INDEX_PHONENUMBER	 = 2;
	public final static int INDEX_ADDRESS		 = 3;

	// 一种有意义的排列顺序
	int		 id;
	String	 name;
	String	 phoneNumber;
	String	 address;

	public Student() {
	}

	public Student(int id, String name, String phoneNumber, String address) {
		// 一种有意义的排列顺序
		this.id				 = id;
		this.name			 = name;
		this.phoneNumber	 = phoneNumber;
		this.address		 = address;

	}

	public Student(Student student) {
		// 一种有意义的排列顺序
		this.id			 = student.id;
		this.name		 = student.name;
		this.phoneNumber = student.phoneNumber;
		this.address	 = student.address;
	}

	private int copyFromCursor(Cursor c) {
		// 一种有意义的排列顺序
		this.id 		 = c.getColumnIndexOrThrow(INDEX_ID);
		this.name 		 = c.getColumnIndexOrThrow(INDEX_NAME);
		this.phoneNumber = c.getColumnIndexOrThrow(INDEX_PHONENUMBER);
		this.address	 = c.getColumnIndexOrThrow(INDEX_ADDRESS);
	}
	
	public static void main(String args[]){
		Student xiaoming	 = new Student(0, "张小明",	 "15010112299",		"新疆维吾尔自治区");
		Student wanggang	 = new Student(1, "王刚",	 "13900000099",		"北京市");
		Student liyue		 = new Student(2, "李越",	 "18510112299",		"西藏藏族自治区");
		Student wangli		 = new Student(3, "王丽",	 "13588112299",		"云南省");
	}

}
