    Default What is end of input character?

    Hi there!
    What is end of input character? I wanted to read in input from standard input and find a max but i don't know it does not work. Here is my code:
    Java Code:
    import java.util.ArrayList;
    import java.util.Scanner;
    public class maxNum {
    	public static void main(String[] args) throws IOException{
    		BufferedReader buff=new BufferedReader(new InputStreamReader(;
    		ArrayList<Integer> arr= new ArrayList<Integer>();
    	//	String s;
    		//Integer i=0;
    		Integer max=0;
    		for(int j=0; j<arr.size(); j++){
    			max=Math.max(max, arr.get(j));
    Any help? thanks in advance!

    Java Code:
    while(!=-1) {
    You read twice. That means you are only actually reading half the bytes into your array.
    You need to assign that first read to a variable and then add that variable to your array.
    Please do not ask for code as refusal often offends.
