java - 如何将2个键盘输入带到java中的二维数组？

Question

I want to create a 2D String array which stores name and address which are given as keyboard inputs. eg: name 1 address 1; name 2 address 2;

import java.util.Scanner;
class Main {

  public static void main(String[] args) {    

    Scanner sc = new Scanner(System.in);    
    String[][] array = new String[3][2];
    for (int i = 0; i < 3; i++)
  {
    for(int j = 0; j < 2; j++)
    {     
        array[i][j] = sc.nextLine();
    }

    System.out.println(array[0][0]);
  }
}

in here I want to print a statement asking to enter the name eg. System.out.println("Enter name:"); after that I want to write another statement asking to enter the address eg.System.out.println("Enter the address"); but i cant figure out how do that in a 2d array

Answer 1

How about something like this?

public static void main(String[] args) {
    int rows = 3;
    int cols = 2;

    Scanner sc = new Scanner(System.in);
    String[][] array = new String[rows][cols];

    for (int row = 0; row < rows; row++) {
        System.out.println("Enter name:");
        array[row][0] = sc.nextLine();

        System.out.println("Enter the address:");
        array[row][1] = sc.nextLine();
    }

    // Print out array
    for (int row = 0; row < rows; row++) {
        for (int col = 0; col < cols; col++) {
            System.out.print(array[row][col] + ", ");
        }
        System.out.print(";");
    }
}

Output:

Person 1, Address 1, ; Person 2, Address 2, ; Person 3, Address 3, ;
