第一步:创建一个Java项目 首先,你需要在你的开发环境中创建一个Java项目。例如,如果你使用IDEA或Eclipse,可以选择新建Java项目。 第二步:编写一个Java类 接下来,在你创建的项目中新建一个Java类。例如,我们可以命名这个类为NewlineExample。 publicclassNewlineExample{// 这是一个Java类,负责展示如何在字符串中使...
Adding a new line in Java is as simple as including “\n”, “\r”,or “\r\n”at the end of our string. 2.1. Using CRLF Line-Breaks For this example, we want to create a paragraph using two lines of text. Specifically, we wantline2to appear in a new line afterline1. For a...

newLine()是换行 readLine()是读取一行数据 newLine()是换行后，就可以使用readLine()来一行行读取数据 参考资料：还有其他问题的话，给我发百度消息 2L

The method for inserting a newline varies depending on the programming language. In many programming languages, you can use the escape sequence "\n" to represent a newline. For example, in C, C++, Java, and Python, you can use "\n" within a string to insert a newline. In languages...
