Java – you need to read in the ArrayList and separate positive and negative numbers
•
Java
I need to read 10 integers into ArrayList and program them into two groups: "positive integers" and "negative integers"
I have two ArrayLists and an IF statement to determine where each integer should go, but I don't know what variables to use to make this work This is what I have done so far:
import java.util.*;
public class Sort {
public static void main (String [] args) {
ArrayList<Integer> pos = new ArrayList<Integer>();
ArrayList<Integer> neg = new ArrayList<Integer>();
Scanner sc = new Scanner(system.in);
int i=0 ;
while(i <= 10) {
System.out.println("enter an integer");
if(??? < 0) { //here is where my question is
neg.add(sc.nextInt());
} else {
pos.add(sc.nextInt());
}
i++;
}
System.out.println("positive numbers" + pos);
System.out.println("negative numbers" + neg);
}
}
Solution
while(i<=10){
while(i<=10){
System.out.println("enter an integer");
int next_int = sc.nextInt();
if(next_int < 0) { //here is where my question is
neg.add(next_int);
} else {
pos.add(next_int);
}
i++;
}
