如何使用java在txt中添加新行，并且不留空格

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

String newLine = "这是新的一行内容";

try {
    BufferedWriter writer = new BufferedWriter(new FileWriter("文件路径", true));
    writer.write(newLine);
    writer.newLine();
    writer.close();
} catch (IOException e) {
    e.printStackTrace();
}

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;

public class AddNewLineToTxt {
    public static void main(String[] args) {
        String newLine = "这是新的一行内容";

        try {
            BufferedWriter writer = new BufferedWriter(new FileWriter("文件路径", true));
            writer.write(newLine);
            writer.newLine();
            writer.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
