Add column of matrices

Hello friends, who can help me to add the columns 8 and 9 of the matrix of this code?

import java.util.Scanner;
public class Project {
static String matrix;
static int ccites=0;
static Scanner sc=new Scanner (System.in);
public static void main(String arg) {

int option=1;
matrix=new String[18][11];
do { System.out.println("Enter: \n1 To record the information of a soccer match played by the Colombia national team "

  • “\n2 To display the information of all the matches played by the Colombian national team” + "\n3 To display the information of all the matches played by the Colombian national team "
  • "\n3 To show the number of matches played by the Colombia national team " + "\n4 To modify the number of matches played by the Colombia national team "
    To modify or update the information of a match taking into account its date " + "\n4 To modify or update the information of a match taking into consideration its date "
  • "\n5 To show the information of the matches where there has been a red card for some of the teams. "
  • "\n6 To calculate the average number of goals per match (the goals scored by both teams are considered). "
  • "\n7 To display the name of the team that scored the most goals ");

option=sc.nextInt();

switch(option){
case 1: register_match();
break;
case 2: show_all_match_information();
break;
case 3: System.out.println("The number of matches played by the Colombian national team were "+ccites);
