//通過剛才的鍵盤錄入一行數(shù)據(jù)并打印其大寫，發(fā)現(xiàn)其實就是讀一行數(shù)據(jù)的原理
//也就是readLine方法
//能不能直接使用readLine方法來完成鍵盤錄入一行數(shù)據(jù)的讀取呢
//readLine方法是字符流BufferedReader類中的方法
//而鍵盤錄入的Read方法是字節(jié)流InputStream的方法
//那么能不能將字節(jié)流轉(zhuǎn)成字符流 在使用字符流緩沖區(qū)的readLine方法呢？
//獲取鍵盤錄入對象
InputStream in = System.in;
//將字節(jié)流轉(zhuǎn)成字符流對象， 使用轉(zhuǎn)換流InputSreamReader
InputStreamReader isr = new InputStreamReader(in);
//為了提高效率，將字符串進行緩沖技術(shù)高校操作，使用BufferedReader
BufferedReader bur = new BufferedReader(sir);
//獲取鍵盤錄入常見寫法
//BufferedReader bur = new BufferedReader(new InputStreamReader(System.in));
//輸出設(shè)備
