File sourceFile1 = new File(ls_tempImage1);
File destFile1 = new File(destFileUrl1);
fileLength1 = sourceFile1.length();
FileInputStream fis1 =null;
FileOutputStream fos1 =null ;
try {
fis1 = new FileInputStream(sourceFile1);
fos1 = new FileOutputStream(destFile1.getAbsolutePath(),false);
catch(FileNotFoundException fnfe) {}
finally {
try {

for (i=1;i<=fileLength1;i++){
} catch(IOException ioe) {
System.err.println("File Closing error: " + ioe);

The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at "JavaRanch Naming Policy" . We require names to have at least two words (not just letters), separated by a space, and strongly recommend that you use your full real name. We want to get to know you as a Professional. Please choose a new name which meets the requirements and re-register.
Also this question is more appropriate to the I/O forum, so I will move it there.
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
