55. File Input/Output (continued) Java Programming: From Problem Analysis to Program Design, 5e The statement in Line 1 assumes that the file prog.dat is in the same directory (subdirectory) as your program. However, if this is in a different directory (subdirectory), then you must specify the path where the file is located, along with the name of the file. For example, suppose that the file prog.dat is on a flash memory in drive H . Then the statement in Line 1 should be modified as follows: Scanner inFile = new Scanner( new FileReader("h:prog.dat")); Note that there are two after h: . Recall that in Java is the escape character. Therefore, to produce a within a string you need . (Moreover, to be absolutely sure about specifying the source where the input file is stored, such as the flash memory in drive h: , check your system’s documentation.)
