Reading integer from file This program explains how we can read numerical data from a file and process it.  Remember we need following steps to read from a file: step-1: create File object and connect the file containing data by passing fileName in object as: File file = new File("outputFile.txt"); Step-2: Test whether the file exists, if it exists  step-3: Create object to Scanner class and connect it to the file containing data pointed by File object "file" as shown below: Scanner inputFile = new Scanner(file); Step-4:  Check if the line being pointed by nextLine() has the data, this is done asL: while(inputFile.hasNext()) Step-5 read from thefile sum += inputFile.nextInt(); Now see the complete program, of reading integer values from the file and count the number values in file and
