java换行符的使用方法:1、换一行【System.out.print("\n")】;2、换两行【System.out.println("\n\n")】;3、换三行【System.out.println("\n\n"\n)】。
java换行符的使用方法:
可以使用Java中\n和\r的换行,不过也是有区别的,如下:
\r 叫回车 Carriage Return
\n 叫新行 New Line
但是都会造成换行,使用System.getProperty("line.separator")来获取当前OS的换行符
常用:
第一种:使用System.out.println()//这是换一行。
第二种:使用System.out.print("\n");//这也是换一行.
第一种和第二种差不多。只是,如果你要换两行,三行,多行的话。
就用:System.out.println("\n\n");换两行
换三行:System.out.println("\n\n"\n);
1、问题
windows平台的换行符为/r/n;
linux平台的换行符为/n;
java程序中如何将不同平台用户输入的换行符转换成特定系统的换行符.
2、解答
java 代码
1. String userInputString = userInput; 2. userInputString = userInputString.replaceAll ( "\r", "" ); 3. userInputString = userInputString.replaceAll ( "\n","\\\\"+System.getPropert("line.separator"));
