Here is a simplest Java Program to read a file line by line in reverse order using Java8 APIs. Try it out and let me know if you see any issue with this.
Java 8 Stream is another way (albeit cleaner) of reading a file line by line. We can use Files.lines() static method to initialize a lines stream like below: try { // initialize lines stream Stream<String> stream = Files.lines(Paths.get("examplefile.txt")); // read lines stream.for...
