can plss anybody help me how to write a simplesorting vector in this example . i am very confused
i want to use a simplesorting Vector in place of a vector .i need to sort all the names in the vector so that i can read each and every name
so wat i am doing initially i am giving fc.list and adding all the names of the files in a vector fileNames .
BUt i have read that to apply simpleSortingVector we need to apply the comparator in the begining .
i have written a comparator class but that class from which it is getting data for compare is set after the reading of the vector with the vector data itself.
i mean i have to compare the files names which will be in the vector after it is read then that vecctor i am changing to an array and then that data i initializing to the bean class
i know i have hotch pochted the whole code .I am attaching a sippet of the code plsss correct where i am wrong or suggest me something else where i can compare the file names in the vector , sort them in proper order and retrieve them .
public void readDataFrmZip()
{
Enumeration fileEnum;
String _currentFile;
DataOutputStream dout = null;
FileConnection fileConn=null,fConn=null;
FileConnection file = null;
SimpleSortingVector filesVector= new SimpleSortingVector();
filesVector.setSortComparator(new FileNameComparator());
filesVector.setSort(true);
String path = "file:///SDCard/Databases/glide/Flights/" ;
String extensions = "*.zip.part";
try
{
fConn = (FileConnection)Connector.open("file:///SDCard/Databases/glide/FlightsZip"+"/Flights.zip" , Connector.READ_WRITE);
fileConn = (FileConnection)Connector.open("file:///SDCard/Databases/glide/FlightsZip/" , Connector.READ);
if (!fConn.exists())
{
fConn.create(); // create the file if it doesn't exist
}
OutputStream out = fConn.openDataOutputStream();
if (path == null)
{
//Read the file system roots.
fileEnum = FileSystemRegistry.listRoots();
while (fileEnum.hasMoreElements())
{
filesVector.addElement((Object)fileEnum.nextElement());
}
}else{
fileEnum = fileConn.list("*.part*", true); // list of all files in folder flights
while(fileEnum.hasMoreElements())
{
if (extensions == null)
{
filesVector.addElement((Object)fileEnum.nextElement());
}else
{
_currentFile = ((String)fileEnum.nextElement());
filesVector.addElement((Object)_currentFile); //this is where i am adding all the file names to the vector
}
}
}
filesVector.reSort();
int size= filesVector.size();
String temp;
flightsVector = filesVector;
FileName filecomp[] = new FileName[size];
String fileNames[] = new String[size];
filesVector.copyInto(fileNames);
for(int i=0;i<=size;i++)
{
temp = fileNames[i];
filecomp[i] = new FileName();
filecomp[i].setName(temp);
}
for(int i =0;i<=size;i++)
{
System.out.println("***********************"+fileNames[i]);
}
for(int i=0;i<=size;i++)
{
i++;
System.out.println("/////////////"+fileNames[i]);
String flight = "Flights_20111202.zip.part";
String path1 ="Flights_20111202.zip.part" +i ;
System.out.println("+++++++++++++"+path1);
file = (FileConnection)Connector.open("file:///SDCard/Databases/glide/FlightsZip/"+path1,Connector.READ);
InputStream in = file.openDataInputStream();
int count=0;
byte [] data =new byte[1048576];//IOUtilities.streamToBytes(in);
while ((count = in.read(data)) != -1)
{
out.write(data,0,count);
System.out.println("########## " + i + " = " + count);
}
in.close();
file.close();
}
out.flush();
out.close();
}catch (IOException e) {
System.out.println("Exc in readDataFrmZip: "+e);
e.printStackTrace();
}finally{
try {
fConn.close();
fileConn.close();
} catch (IOException e) {
// TODO Auto-generated catch blockF
e.printStackTrace();
}
}
}
The above given was the method.
Now the comparator class
public class FileNameComparator implements Comparator {
public int compare(Object o1, Object o2) {
FileName emp1 =new FileName();
FileName emp2= new FileName();
String file1Name = ((FileName)emp1).getName();
String file2Name = ((FileName)emp2).getName();
//uses compareTo method of String class to compare names of the employee
return file1Name.compareTo(file2Name);
// return 0;
}
}
the classfrom which this comparator cass gets the data to compare that class is as follows:
public class FileName {
private String name;
public void setName(String name){
this.name=name;
}
public String getName(){
return this.name;
}
}
plss help me how should i sove my this problem .plssss help meee plsss
