java Access File through multiple threads - Stack Overflow
I tried to use synchronization but i couldn't get a way ensure that the first thread is reading the first file and writing it to File F4 and second reading the second file and writing the contents to F4 once file one is completely written, and there was one more condition that i cannot use join.... 2) I am trying to use threads to improve performance as one thread could read the file and another could write the file. Also I am using a queue in between the two threads, plus using the thread wait(), notify() mechanism for synchonization and to assure that the queue size does not increase too much. But somehow I am getting the same performance as the once without threads would give.

Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient....
Write a java program or function to sort a text file containing some records in single or multiple columns. Your program should take one text file containing some records as input, should sort the records on a particular column and write the sorted records in another text file. See the below image.

How To Read A File Using Multiple Threads In Java

10/11/2005 · One thread must read this and there must be multiple threads to write every 10 lines read and write to 10 different destination files. I have developed a code where inn there are 3 different classes one for read,one for write and another main class which calls these two classes.

  • 12/10/2010 · Alternatively if the file is really big and you don't want to read it entirely into memory FileChannels are thread safe. According to the JavaDoc if you use the read methods that take an absolute position the operations will be performed concurrently (provided that the underlying implementation supports this).
  • Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient.
  • I tried to use synchronization but i couldn't get a way ensure that the first thread is reading the first file and writing it to File F4 and second reading the second file and writing the contents to F4 once file one is completely written, and there was one more condition that i cannot use join.
  • 19/08/2004 · If you want to safely access a file from more than one thread you would be wise to wrap the file access with synchronized methods. Stefan's suggestion makes sense as well since using a queue frees your thread from waiting around for other threads and for the actual write overhead.
