[英]Loading break line sign “\n” from file
I need to load from text file text which I will be replacing in other string. 我需要从文本文件中加载要替换为其他字符串的文本。 For example I have text file:
例如我有文本文件:
\n;(br)
After loading this file I need to change all break lines to (br)
so I will receive one line string. 加载此文件后,我需要将所有换行更改为
(br)
这样我将收到一个行字符串。 Problems is when I'm loading text from file - I don't get string \\n;(br)
but \\\\n;(br)
问题是当我从文件加载文本时-我没有得到字符串
\\n;(br)
但是\\\\n;(br)
Anyone know how to do that? 有人知道该怎么做吗?
My code - I know that I'm adding '\\n' in method applyFilters but it is because that there can be situation when I don't whant to change that. 我的代码-我知道我在方法applyFilters中添加了'\\ n',但这是因为在某些情况下我不想更改它。
void loadSource(){
File file = new File(sourcePath);
BufferedReader reader=null;
String text;
try{
reader = new BufferedReader( new FileReader(file));
}catch(FileNotFoundException e){
e.printStackTrace();
}
try{
while((text = reader.readLine()) != null){
sourceText.add(text);
}
}catch(Exception e){
e.printStackTrace();
}
}
void loadFilters(){
File file = new File(filterPath);
BufferedReader reader=null;
String text;
try{
reader = new BufferedReader( new FileReader(file));
}catch(FileNotFoundException e){
System.out.println("Błąd, brak pliku źródłowego");
e.printStackTrace();
}
try{
while((text = reader.readLine()) != null){
filterText.add(text);
}
}catch(Exception e){
e.printStackTrace();
}
}
void applyFilters(){
for (String s : sourceText){
finalText = finalText+ s + "\n";
}
for(String filter : filterText)
{
finalText = finalText.replace(filter.split(";")[0],filter.split(";")[1]);
}
System.out.println(finalText);
}
It sounds like you want the "\\n" in your text file to represent a newline character rather than a backslash followed by an n. 听起来您想让文本文件中的“ \\ n”代表换行符,而不是后跟n的反斜杠。 Have a look at this question:
