在此代码中,使用一个文件(new.txt)完成了一些操作 我想将下面代码的输出存储在另一个文件中....
public static void main(String a[]) throws Exception {
try {
Arrays.stream(Files.lines(Paths.get("new.txt")).collect(Collectors.joining())
.replaceAll("^.*?1002|1003(.(?!1002))*$", "\n") // trim leading/trailing non-data
.split("1003.*?1002")) // split on end-to-start-of-next
.forEach(System.out::println);
} catch (IOException e) {
e.printStackTrace();
}
}

由于您已将整个文件内容保留在内存中,因此非流解决方案更直接。
finale String EOL = "\n";
txt = txt.replaceAll("^.*?1002|1003(.(?!1002))*$", EOL ) // trim leading/trailing non-data
txt = txt.replaceAll("1003.*?1002", EOL ) // split on end-to-start-of-next
<强> 加了: 强> 虽然逻辑逃避了我,但替换可能应该是:
package controllers
import play.api.libs.mailer._
import java.io.File
import org.apache.commons.mail.EmailAttachment
import javax.inject.Inject
import play.api._
import play.api.mvc._
import scala.concurrent.Future
import play.api.libs.json._
class MailerApi @Inject() (mailerClient: MailerClient) extends Controller {
def sendEmail = Action.async(parse.json) { request =>
val subject: String = (request.body \ "subject").as[String]
val cid = "1234"
val email = Email(
subject,
"Me <email1@gmail.com>",
Seq("Miss TO email2@gmail.com"),
// adds attachment
attachments = Seq(),
// sends text, HTML or both...
bodyText = Some("A text message"),
bodyHtml = Some("content")).addBcc("<email1@gmail.com>")
mailerClient.send(email)
Future.successful(Ok("ok !!"))
}
}

你可以尝试:
public static void main(String a[]) throws Exception
{
try {
PrintWriter os = new PrintWriter("output.txt");
Arrays.stream(Files.lines(Paths.get("new.txt")).collect(Collectors.joining())
.replaceAll("^.*?1002|1003(.(?!1002))*$", "\n") // trim leading/trailing non-data
.split("1003.*?1002")) // split on end-to-start-of-next
.forEachOrdered(os::println);
}
catch (IOException e)
{
e.printStackTrace();
}
}

不确定你究竟想要什么。这是一种方法,我会做什么 您可以直接从终端
执行此操作javac myFile.java
java ClassName > myfile.txt
这会将您的输出保存到文件'myfile.txt'
