java如何实现写入并保存txt文件?
(推荐学习:java视频教程)
实例代码如下:
package TEST;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
public class BufferedWriterDemo {
public static void main(String[] args) throws IOException {
write("E:1.txt"); //运行主方法
}
public static void write(String path)
throws IOException {
//将写入转化为流的形式
BufferedWriter bw = new BufferedWriter(new FileWriter(path));
//一次写一行
String ss = "测试数据";
bw.write(ss);
bw.newLine(); //换行用
//关闭流
bw.close();
System.out.println("写入成功");
}
}
