问题描述

在我的servlet中，我给了 out.print 和 out.write 。但两者都在浏览器中打印。

In my servlet I gave both out.print and out.write. but both prints in the browser.

这两者之间的确切差异以及何时使用 out.print 和 out.write ？

What is the exact difference between these two and when to use out.print and out.write ?

推荐答案

基本区别在于 out.write（）如果你把它传给null就会爆炸：

The basic difference is that out.write() explodes if you pass it a null:

String s = null;
out.print(s); // outputs the text "null"
out.write(s); // NullPointerException
