Write a function that will accept a series of integer values in a list. Terminate sequence by typing -999. Then display the content of list.?

Answer 1

public static final void readIntList() {

// set up our input buffer

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

String currentLine;

// I'll use a linked list for this;

// replace it with whatever best suits your purpose

List<Integer> intList = new LinkedList<Integer>();

// loop until we read -999

while (!(currentLine = in.readLine()).equals("-999")) {

try {

// convert from string to int

int currentNumber = Integer.parseInt(currentLine);

// add to the list

intList.add(currentNumber);

} catch (final NumberFormatException ex) {

// we go here if the user didn't type in an integer

}

}

// display our lovely list

System.out.println(intList);

}
