java 文件的操作

1、创建文件并写入字符串
package util;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.text.SimpleDateFormat;
import java.util.Date;

public class UtilStorageFile {

public static void stroageInfo(String fileDir,String resouceStr){

String dd =  UtilStorageFile.class.getResource("").getPath();

File file  = new File(fileDir,new SimpleDateFormat("yyyy-MM-dd HH-mm-ss").format(new Date())+".txt");

BufferedWriter output=null;

try {


output = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(file,true)));

output.newLine();

output.write(resouceStr);


} catch (Exception e) {

System.out.println("存储字符串时信息发生异常...");

e.printStackTrace();

}finally{

try {

output.flush();

output.close();

} catch (Exception e) {

System.err.println("关闭输出流发生异常...");


}
}
}
}
