Question

Consider the following code: scanner inputstream = null; try {inputstream = new scanner(new FileInputstream ("data.txt"));} catch(FileNotFoundException e) {system out.println("Error opening files"); system.exit(e);} while (inputstream.hasNextline()) {string aline = null; aline = inputstream.nextLine();} system.out.println(aline +^-^- + aline); and the following contents of data.txt: double toil trouble What does the program output? double double toil toil trouble trouble trouble trouble double toil trouble trouble trouble An error occurs

Explanation / Answer

Answer:

As per the code, program will not compile first. Becuase System.out.println(aLine + " "+aLine);

this statemnt is trying to print "aLine" String object value after while loop. But this object aLine declared in while loop so this aLine object will not be visible to outside of the while loop.

So here i am assumming that this statement System.out.println(aLine + " "+aLine); is in while loop.

if it is in while loop, then it will print below output

double double

toil toil

trouble trouble
