My simple solution java

public class Main {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        int rounds=scanner.nextInt();
        int max=0;
        int current=1;
        int player1cum=0;
        int player2cum=0;
        while (rounds>0) {
            int player1=scanner.nextInt();
            int player2=scanner.nextInt();
            player1cum+=player1;
            player2cum+=player2;
            int lead=player1cum-player2cum;
            if (lead>0&&max<=lead)
            {
                current=1;
                max=lead;
            }
            else if(lead<0&&max<=Math.abs(lead)) {
                current=2;
                max=Math.abs(lead);
