类型不匹配：无法从String转换为int-java

Question

import java.util.*;

public class matchScore{

  public static void main(String[] args){

    String opt;
    String home_team_name;
    String away_team_name;
    int home_team_score;
    int away_team_score;

    String[] name = new String[10];
    int[] score = new int[10];

    System.out.println("Retype an option:\n");
    System.out.println("Home teams");
    System.out.println("Away teams");
    System.out.println("Outputs");

    Scanner scan = new Scanner(System.in);

    opt = scan.nextLine();

    if(opt == "Home teams"){
      System.out.println("Entre first home team name: ");
      name[0] = scan.nextLine();
      System.out.println("Entre first home team score: ");
      score[0] = scan.nextLine();

      System.out.println("Entre second home team name: ");
      name[1] = scan.nextLine();
      System.out.println("Entre second home team score: ");
      score[1] = scan.nextLine();

      System.out.println("Entre third home team name: ");
      name[2] = scan.nextLine();
      System.out.println("Entre third home team score: ");
      score[2] = scan.nextLine();

      System.out.println("Entre forth home team name: ");
      name[3] = scan.nextLine();
      System.out.println("Entre forth home team score: ");
      score[3] = scan.nextLine();

      System.out.println("Entre fifth home team name: ");
      name[4] = scan.nextLine();
      System.out.println("Entre fifth home team score: ");
      score[4] = scan.nextLine();

      System.out.println("Entre sixth home team name: ");
      name[5] = scan.nextLine();
      System.out.println("Entre sixth home team score: ");
      score[5] = scan.nextLine();

      System.out.println("Entre seventh home team name: ");
  name[6] = scan.nextLine();

      System.out.println("Entre seventh home team score: ");
      score[6] = scan.nextLine();
    }
  }
}

Answer 1

使用

score[0] = scan.nextInt();

而不是

score[0] = scan.nextLine();

因为Score[]是int[]的数组。
