java实现读取txt文件并以在每行以空格取数据

package test4; import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException; public class ExplaceSql {	public static void main(String[] args) {		 String filePath = ExplaceSql.class.getResource("").getPath()+"aaa.txt"; // 文件路径		 read(filePath);	}		/**	 * 读取内容	 */	public static String read(String filePath){		BufferedReader br = null;		String line =null;		//StringBuffer buf = new StringBuffer();		try {			//根据文件路径创建缓冲输入流			br = new BufferedReader(new FileReader(filePath));//filePath中是aaa.txt文件			String str = "";						//循环读取文件的每一行，对需要修改的行进行修改，放入缓冲对象中			 while ((line = br.readLine()) != null) {				 //设置正则将多余空格都转为一个空格				 str=line+"/r/n";				 String[] dictionary = str.split("//s{2,}|/t");				 for(int i=0;i<dictionary.length;i++){					str = "insert into tablename values("+ dictionary[0]+",'"+dictionary[1]+"',"+dictionary[2]+"')";				 }				 System.out.println(str);				 			 }		} catch (Exception e) {			e.printStackTrace();		}finally {	   if (br != null) {// 关闭流	    try {	     br.close();	    } catch (IOException e) {	      br = null;		  }		  }		}		return null;	}	}
