换行符(Newline character)是一种特殊字符,用于在文本中表示换行的位置。在不同的操作系统和编程语言中,换行符可能有所不同。在Java中,换行符被表示为\n。 Java中String类型的换行问题 String类型是不可变的,一旦创建就不能被修改。在Java中,我们常常需要通过String类型来处理文本,包括换行符。然而,由于String的不...

2.解答 java 代码 1. String userInputString = userInput; 2. userInputString = userInputString.replaceAll ( "\r", "" ); 3. userInputString = userInputString.replaceAll ( "\n", "\\\"+System.getPropert("line.separator"));
String newLine=System.getProperty("line.separator"); 如果你的 JDK 版本是在 7 以上的版本的话,你可以直接使用系统提供的: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 System.out.println(System.lineSeparator()); 方法。 我们将会使用newLine变量在后续的代码中插入一个新行。
