将java输出导出为文本

首次使用java社区，但我不明白如何格式化代码才能在此处正确显示。将输出导出为记事本文本格式的教程让我感到困惑。我将我的代码上传到了一个文本文件中，供大家看到。将java输出导出为文本

的代码基本上是用于比较真或假的课堂提问阵列

请在这里用IDE的基本格式发布相关代码。本网站中的其他人可以为您设置格式，然后您将学习如何操作。 –

我做了它我认为 –

我觉得你是想用java.io.BufferedWriter在打印线的位置。

FileWriter fw = new FileWriter(file.getAbsoluteFile());   
BufferedWriter bw = new BufferedWriter(fw);  
bw.write(content); 
bw.close();

哪一行我执行此操作。 Java真的让我困惑？ –

@StefanHex'File file = new File（studentIDArr [i] .toString（）+“。txt”）;' 'FileWriter fw = new FileWriter（file.getAbsoluteFile（））;' 'BufferedWriter bw = new BufferedWriter FW）; ' 'bw.write（“Student ID：”+ studentIDArr [i] +“\ n”）;' 'bw.write（“Student Score：”+ score +“\ n”）; 'bw.write（“学生通过”+通过+“问题\ n”）; bw.write（“学生失败”+失败+“问题\ n”）; bw.close（）;' – SparkleGoat

@StefanHex为您做了这项工作？你可以选择它作为答案：D – SparkleGoat
