Question

我需要代码将Aidan Dowling这样的单行写入文本文件。到目前为止我的代码是：

package battleships.startmenu;
import java.util.Scanner;
public class Startmenu {

    public static void main(String[] args) {
        System.out.print("Hello! Please enter your first name: ");
        Scanner reader = new Scanner(System.in);
        String a;
        String b;
        a=reader.next();
        System.out.print("Enter your second name: ");
        b=reader.next();

        System.out.println("Hello " + a+ " " + b + "!");
        System.out.println("\tHello");
        String name;
        name = a + b;
    }
}

我希望变量名称打印到名为name.txt的文档

Answer 1

创建作家

PrintWriter writer = new PrintWriter("name.txt", "UTF-8");

写一行

writer.println(name);

关闭作家

writer.close();

Answer 2

将name写入name.txt：

Files.write(Paths.get("name.txt"), Arrays.asList(name), StandardCharsets.UTF_8);

用于将变量保存到文本文件的Java代码
