How to write multiple lines in a file when this multiple lines take as a input from a JTextarea?
提问by Animesh Kumar Paul
I take multiple lines as a input from a JTextarea, If I write it in a file, then I get that the multiple lines are write in a one line in file
我将多行作为 JTextarea 的输入，如果我把它写在一个文件中，那么我得到多行写在文件的一行中
Examples:
例子：
In JTextArea:
在 JTextArea 中：
I
am
a
student
Means: variable.text="I'\n'am'\n'a'\n'student"; When I write the string s in file I get:
意思是：variable.text="I'\n'am'\n'a'\n'student"; 当我在文件中写入字符串 s 时，我得到：
I am a student
But I want that the file will contain the same things as I give as a input means--->
但我希望该文件将包含与我作为输入方式提供的相同内容--->
I
am
a
student
This is the code of writing a file :
这是写文件的代码：
BufferedWriter out = new BufferedWriter(
new OutputStreamWriter(
new FileOutputStream(file), "UTF16"));
int size=1;
for(Tableclass variable:tablevector)
{
out.write(variable.Text);
out.newLine();
size++;
}
out.close();

Slighty better version would be :
稍微好一点的版本是：
try {
PrintWriter fstream = new PrintWriter(new FileWriter("log.txt"));
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
for(String word : jTextAreaName.getText().split("\n")) {
fstream.println(word);
}
fstream.flush();

Use out.newLine();
使用 out.newLine();
BufferedWriter out = new BufferedWriter(
new OutputStreamWriter(
new FileOutputStream(file), "UTF16"));
int size=1;
for(Tableclass variable:tablevector)
{
out.write(variable.Text);
out.newLine();
size++;
}
out.close();

find this char in your string char(10) or char(13)
在你的字符串 char(10) 或 char(13) 中找到这个字符
int index = textarea.firstIndexOf(CHAR(10));
