Java SE 7 新功能與改進:try-with-resources 述句

介紹 try-with-resources 述句可以讓我們在 try 述句中宣告一到數項資源。當我們說某個物件是一項資源時,意味著該物件實作了 java.lang.AutoCloseable 或是它的子介面 java.lang.Closeable,並且當程式不再使用它們時,我們需要將其關閉。try 新增的述句確保每項資源在區段結束時都會被關閉。 早期我們都必須要自行處理資源的關閉,但現在我們可以藉助此一述句來簡化程式。下例會從檔案中讀取第一行,它使用 BufferedReader 物件來讀檔。B …

Java SE 7 新功能與改進:switch 指令支援字串

在 Java SE 7 中,可以在 switch 述句中使用 String 物件: switch 述句會使用 String.equals 方法來比較每一個 case 標籤的字串物件,因此在 switch 述句中的字串比對是有大小寫分別的。 和一連串的 if-then-else 相比,在 switch 述句中使用字串會更有效率,並且容易閱讀。 …
