(1)掌握InputStream、OutputStream、Reader、Writer的继承体系。 (2)掌握字节流(FileInputStream、DataInputStream、BufferedInputStream、FileOutputSteam、DataOutputStream、BufferedOutputStream)和字符流(BufferedReader、InputStreamReader、FileReader、BufferedWriter、OutputStreamWriter、PrintWriter、FileWriter),并熟练运用。
Map<String, String> map =newHashMap() {{ put("map1","value1"); put("map2","value2"); put("map3","value3"); }}; 这段代码其实是创建了匿名内部类,然后再进行初始化代码块。 这一点我们可以使用命令javac将代码编译成字节码之后发现,我们发现之前的一个类被编译成两个字节码(.class)文件...
