BufferedReader in = new BufferedReader(new FileReader("foo.in")); この例は指定されたファイルからの入力をバッファします。 バッファリングせずにread()、readLine()を使うと、呼び出しごとにファイルからバイトを読み込み、文字型に変換し、そのたびに復帰するので、非常 Returns a stream consisting of the elements of this stream, sorted according to natural order. If the elements of this stream are not Comparable, a java.lang.ClassCastException may be thrown when the terminal operation is executed. For ordered streams, the sort is stable. For unordered streams, no stability guarantees are made. Mar 05, 2015 · Many times we need to deal with UTF-8 encoded data in our application. This may be due to localization needs or simply processing user input out of some requirements. Even data sources may provide data in this format only.
