什么是程序设计

一般情况下，考研有择校应该注重所报考的院校的知名度，比如说是不是985，211等，但是并不是所有的学校 计算机专业都非常强，这时你可以考虑一下综合排名不是特别靠前，但是个别专业在业内很有知名度的专业性院校。比如说北邮，或者其他邮电类学校。具体选择需要结合自己的实力，和兴趣，个人观点，为了长远发展，建议还是报考综合性院校要好一点，

public class Rectangle{ private int width; private int height; public Rectangle(){ thiswidth = 10; thisheight = 10; } public Rectangle(int width, int height){ thiswidth = width; thisheight = height; } public int area(){ return width height; } //省略getter/setter }

太多了，不想写注释，看不懂联系我！

，但是毕竟很相似了，因为解决问题的方法是一致的
