Java program question

how do you solve this question, shown below The entry code for a room is 2 3 4. The user enters one digit at a time and may type in any number of wrong values, but as soon as the correct sequence is entered a â??door openâ?? message should be displayed. E.g. 2 5 2 3 4 and this what i done so far Scanner input = new Scanner (; int code1 = 2; int code2 = 3; int code3 = 4; int code = 0; for(int index = 0; code != code1 && code != code2 && code != code3; index++) { System.out.println("Enter code"); code = input.nextInt(); if ((code == code1) && (code == code2) && (code == code3)) { System.out.println("door open"); } else if ((code != code1) && (code != code2) && (code != code3)) { System.out.println("wrong code"); } }

readAndPrint Method

Create a class called LineReader within your examination directory. Add a public void method called readAndPrint() that attempts to open and read a text file called input.txt located within the same directory as the class (so do not hard code a path into your solution). You will find input.txt in your examination directory to use for testing. The readAndPrint() method must open the file and read the contents line by line. Each line containing text should be printed to the standard output (e.g. terminal window). If a line in the file is empty (i.e. has no text) then it should not be printed; instead the method should create and throw a new Exception and no further lines should be read or displayed ( do not catch the exception within your method, it must be thrown to whatever method called readAndPrint() originally).
