我有一個文件*.txt檔裡面內容是這樣 In this below-sea-level basin, steady drought and record summer heat make Death Valley a land of extremes. Yet, each extreme has a striking contrast. Towering peaks are frosted with winter snow. Rare rainstorms bring vast fields of wildflowers. Lush oases harbor tiny fish and refuge for wildlife and humans. Despite its morbid name, a great diversity of life survives in Death Valley. 在程式碼裡面用 while(bufferedReader.readLine() != null) { System.out.println(bufferedReader.readLine()); } 結果只會顯示第二行和第四行 land of extremes. Yet, each extreme has a striking contrast. Towering peaks are frosted with and refuge for wildlife and humans. Despite its morbid name, a great diversity of life survives 但是如果用 String str = null; while((str=bufferedReader.readLine()) != null) { System.out.println(str); } 就可以顯示文件全部的內容,但是請問這兩種方式在邏輯上好像沒甚麼不一樣????請問為什麼會有這樣的狀況? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 61.228.249.225 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/java/M.1579806122.A.288.html
