string 分割

String分割-初体验

public void upload(Photo photo,String filepath) throws IOException, BOException{
File files=new File(filepath);
FileOutputStream fos = null;
FileInputStream fis = null;
String[] testString = filepath.split("[\\\\]");(回车=="\n”)
String lastString=testString[testString.length-1];
String[] testString2 = filepath.split("[.]");
String lastString2=testString2[testString2.length-1];此程序用没用到
try {
fos = new FileOutputStream("d://root//"+lastString);
fis = new FileInputStream(files);
byte[] buffer = new byte[1024];
int len = 0;
while ((len = fis.read(buffer)) > 0) {
fos.write(buffer, 0, len);
}
} catch (FileNotFoundException e) {
throw e;
} finally {
try {
if (fos != null) {
fos.close();
}
if (fis != null) {
fis.close();
}
} catch (IOException e) {
throw e;
}
}
try{
String setString="d://root//"+lastString;
photo.setId(sequenceService.getSynUid());
photo.setFilePath(setString);
photoDao.create(photo);
}catch(DAOException e){
log.error("Error occurred when create methods of PhotoBOImpl",e);
throw new BOException("存储数据失败",e);
}
}



package test;

import java.util.Scanner;

public class Stringtest {

public static void main(String[] args) {
String [] temp;
String sss="a.rar";
String[] array=sss.split("[.]");
System.err.println(array[1]);//=rar
Scanner scanner=new Scanner(sss);
scanner.useDelimiter("[.]");
while(scanner.hasNext()){
System.out.println(scanner.next());
}
}

}结果是
a
rar
