Need to run program multiple times

Question

I need to be able to run my compiled java file five times all in the same cmd while only using one .java file... I got it to fully work when i only do it once, but how do i make it repeat everything five times?

Answer 1

while (x=5)
x=x+1
allmycode
}You are right: it's not a good idea to throw "allmycode" into a loop.
so like in a while loop how it kind of "forgets" -or however you phrase it- all
the ints/strings and just starts over with the same ones.This is a good description of what a method is (from a non OO point of view).
It "forgets" its local variables.
I agree with flounder, you should probably make a class for your data and a
collection to store them in. But if this not where you are at the moment, you
can still follow your intuition and make a method that processes the
data line by line - effectively forgetting the work it did on the previous line.
Such a method can be called weithin a simple for-loop.
You example would look like this:import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Adder {
    private static BufferedReader in = new BufferedReader(
            new InputStreamReader(System.in));
    private static String[] inputArr;
    public static void main(String[] args) {
        inputArr = new String[5];
            // First read the iput
        for(int i = 0; i < 5; ++i) {
            getInput(i);
            // Then process it
        for(int i = 0; i < 5; ++i) {
            processInput(i);
    private static void getInput(int line) {
        try {
            inputArr[line] = in.readLine();
        } catch(IOException ioe) {
            ioe.printStackTrace();
            System.exit(1);
    private static void processInput(int line) {
        String[] arr = inputArr[line].split(",");
        int first = Integer.parseInt(arr[0]);
        int second = Integer.parseInt(arr[1]);
        String unit = arr[2].equals("I") ? "Inches" : "CM";
        System.out.printf("%d %s%n", first + second, unit);
}
