ArrayList<Int> Collections.Sort and LineNumberReader Help How to
- by user1819551
I have a issue i can't get it to work now let going to the point a explain in the code thanks.
This is my class: what I want to do is insert the Integers sort the list and buffer writer in a column with out coma. Now I getting this:
[1110018, 1110032, 1110056, 1110059, 1110063, 1110085, 1110096, 1110123, 1110125, 1110185, 1110456, 1110459]
I want like this:
111xxxxx
111xxxx
xxxx.......
I can't do it in single array, have to be in ArrayList.
This is my collecting:
list.addNumbers(numbers);
list.display();
This is my writer: Is buffered
coma.write("\n"+list.display());
coma.flush();<br/>
Here is my class:
public class IdCount {<br/>
private ArrayList<Integer> properNumber = new ArrayList<>();
public void addNumbers(Integer numbers) {
properNumber.add(numbers);
Collections.sort(properNumber);
}
public String display() {
//(I try .toString() Not work)
return properNumber.toString();
}
My second issue is LineNumberReader: This is my collecting and my writing:
try {
Reader input = new BufferedReader( new FileReader(inputFile));
try (Scanner in = new Scanner(input)) {
while (in.hasNext()) {
//(More Code)
asp = new LineNumberReader(input);
int rom = 0;
while (asp.readLine()!=null){
rom++;
}
System.out.println(rom);
coma.write(rom);
This one will not write anything an my System Print give me only 12 0 in column.
