如何从java中的文件中删除breakline [英] How to remove breakline from a file in java

问题描述

public class Compress

{

public static void main（String [] args）抛出FileNotFoundException

{

文件文件=新文件（E：\\input.txt）;

扫描仪扫描仪=新扫描仪（文件）;

PrintWriter writer = new PrintWriter（E：\\sample.txt）;



while（scanner.hasNextLine（））{

String line = scanner.nextLine（）;



String newLine =;



for（int i = 0; i< line.length（）;> if（line.charAt（i）！='\ n'）{

newLine + = line.charAt（i）;

}

}

}

}

}



我尝试了什么：



purus ante non libero。

Nullaacaugue ut odioeleifend

interdueuveurnpulvinaarcpretium



我想将这一段改成一段这句话如下。



purus ante non libero.Nullaacaugue ut odioeleifend interdueuveurnpulvinaarcpretium

public class Compress
{
public static void main( String[] args ) throws FileNotFoundException
{
File file = new File("E:\\input.txt");
Scanner scanner = new Scanner(file);
PrintWriter writer = new PrintWriter("E:\\sample.txt");

while(scanner.hasNextLine()){
String line = scanner.nextLine();

String newLine = "";

for(int i=0; i<line.length();> if(line.charAt(i) != '\n'){
newLine += line.charAt(i);
}
}
}
}
}

What I have tried:

"purus ante non libero.
Nullaacaugue ut odioeleifend
interdueuveurnpulvinaarcpretium"

I want to this paragraph into one line sentence like this following.

"purus ante non libero.Nullaacaugue ut odioeleifend interdueuveurnpulvinaarcpretium"
