java创建txt⽂件并存⼊内容本⽂实例为⼤家分享了java创建txt⽂件并存⼊内容的具体代码，供⼤家参考，具体内容如下import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
public class txtExport {
private static String path = "D:/";
private static String filenameTemp;
public static void main(String[] args) throws IOException {
txtExport.writeTxtFile("你好");
}
/**

}
return flag;
}
/**

*/

// 先读取原有⽂件内容，然后进⾏写⼊操作

// 保存该⽂件原有的内容
