將java輸出導出爲文本

首次使用java社區，但我不明白如何格式化代碼才能在此處正確顯示。將輸出導出爲記事本文本格式的教程讓我感到困惑。我將我的代碼上傳到了一個文本文件中，供大家看到。將java輸出導出爲文本

的代碼基本上是用於比較真或假的課堂提問陣列

請在這裏用IDE的基本格式發佈相關代碼。本網站中的其他人可以爲您設置格式，然後您將學習如何操作。 –

我做了它我認爲 –

我覺得你是想用java.io.BufferedWriter在打印線的位置。

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

哪一行我執行此操作。 Java真的讓我困惑？ –

@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（「學生通過」+通過+「問題\ n」）; bw.write（「學生失敗」+失敗+「問題\ n」）; bw.close（）;' – SparkleGoat

@StefanHex爲您做了這項工作？你可以選擇它作爲答案：D – SparkleGoat
