英文:
Convert multiple lines of string into one string
问题
当我打印s时，它会输出：
what is coding
sky is green
ocean is gold
我该怎么做才能使其输出为：
what is coding sky is green ocean is gold
我已经尝试过 s.replace("\n\r", "") 和使用 System.lineSeparator()，但都没有成功。
我做错了什么？
英文:
Let's say I have a code that reads each line of text from a text file and store it into a variable String s.
while (file.hasNext()){
String s = file.nextLine();
}
When I print s, it prints out
what is coding
sky is green
ocean is gold
What can I do to so that it prints out
what is coding sky is green ocean is gold
I've tried to do s.replace("\n\r", "") and using System.lineSeparator() but to no avail.
What am I doing wrong?

我希望你一切安好。
Scanner scanner = null;
String line = "";
try {
scanner = new Scanner(new File("D:\\ExampleFile.txt"));
} catch (FileNotFoundException ex) {
System.out.println(ex.getMessage());
}
while (scanner.hasNextLine()) {
// 这是你问题的关键。
line += scanner.nextLine();
}
System.out.println(line);

尝试
String fileWithoutNewLine = FileUtils.readFileToString(new File(<PATH_TO_FILE>)).replaceAll("\n", "");
英文:
Try
String fileWithoutNewLine = FileUtils.readFileToString(new File(<PATH_TO_FILE>)).replaceAll("\n", "")
