推荐答案

Java 是一种强烈区分大小写的语言！任何拼写错误或打字错误都会导致错误.亲爱的，下次要小心, 作为 Java 的初学者，期待您 --- 在收到这些错误消息后，您将随着时间的推移而学习.

Java is a strongly case-sensitive language!Any mis-spellings or mis-typings will land you to erranous error.Take care from the next time DEAR,though,it's expected from you as a beginner in Java---you'll learn with time after getting these error messages.

在 Java 中打印语句的正确语法是

The correct syntax for printing out a statement in Java is

System.out.println("Print here whatever you wanna print!");

你得到的错误都是因为你输入了错误的 printIn 而不是 println----see I 而不是l(字母 el 应该在那里，而不是 ahy)！

The error which you are getting is all because you have mis-typed printIn instead of println----see I instead of l(alphabet el should have been there,not ahy)!
