在 Java 中创建一个填充随机整数的文本文件

也许是个愚蠢的问题。但我尝试用 512 个整数填充一个空文本文件，每个整数在每个新行上。我能够将它们随机化并写入文件中，但它们创建了一大堆我想要的数字。谁能帮我纠正我的代码吗？

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.*;

public class Randomizer {

      public static void main() {
        // The target file
        File out = new File("random.txt");
        FileWriter fw = null;
        int n = 512;
        // Try block: Most stream operations may throw IO exception
        try {
            // Create file writer object
            fw = new FileWriter(out);
            // Wrap the writer with buffered streams
            BufferedWriter writer = new BufferedWriter(fw);
            int line;
            Random random = new Random();
            while (n > 0) {
                // Randomize an integer and write it to the output file
                line = random.nextInt(1000);
                writer.write(line + "\n");
                n--;
            }
            // Close the stream
            writer.close();
        } catch (IOException e) {
            e.printStackTrace();
            System.exit(0);
        }
    }
}

运行结束时random.txt的内容： 9463765593113665333437829621346187993554694651813319223268147794541131427390等

            writer.write(line + "\n");

不要用那个。

你用一个BufferedWriter and a BufferedWriter has .newLine().

因此替换为：

writer.write(line);
writer.newLine();
