第一步:创建BufferedWriter实例 在Java 中,我们通常用FileWriter来创建一个通向文件的写入流,然后用BufferedWriter对其进行包装,以提供高效的写入功能。 代码示例: AI检测代码解析 importjava.io.BufferedWriter;importjava.io.FileWriter;importjava.io.IOException;publicclassExportExample{publicstaticvoidmain(String[]args)...
BufferedReader(Reader in):创建一个使用默认大小输入缓冲区的缓冲字符输入流。 BufferedReader(Reader in, int sz):创建一个使用指定大小输入缓冲区的缓冲字符输入流。 代码演示: public class BufferedReaderDemo2 { public static void main(String[] args) throws IOException { //BufferedReader(Reader in):创建...
