Printing Two Dimensional Array in Special Format
- by user554313
Hello everybody,
I am working in a small task that allow the user to enter the regions of any country and store them in one array. Also, each time he enters a region, the system will ask him to enter the neighbours of that entered region and store these neighbours.
I did the whole task but I have a small problem:
I could not be able to print each region and its neighbours like the following format:
Region A: neighbour1 neighbour2
Region B: neighbour1 neighbour2
For example, let us take USA map. I want to print the result as following:
Washington D.C: Texas, Florida, Oregon
and so on.
My code is:
import java.io.*;
import java.util.Arrays;
import java.util.Scanner;
public class Test7{public static void main(String[] args) {
Scanner kb = new Scanner(System.in);
System.out.print("Please enter the number of regions: ");
int REGION_COUNT = kb.nextInt();
String[] regionNames = new String[REGION_COUNT];
String[][] regions = new String[REGION_COUNT][2];
for (int r = 0; r < regions.length; r++) {
System.out.print("Please enter the name of region #" + (r + 1)
+ ": ");
regionNames[r] = kb.next();
System.out
.print("How many neighbors for region #" + (r + 1) + ": ");
if (kb.hasNextInt()) {
int size = kb.nextInt();
regions[r] = new String[size];
for (int n = 0; n < size; n++) {
System.out.print("Please enter the neighbour #" + (n)
+ ": ");
regions[r][n] = kb.next();
}
} else
System.exit(0);
}
for (int i = 0; i < REGION_COUNT; i++) {
System.out.print(regionNames[i] +": ");
for (int k = 0; k < 2; k++) {
System.out.print(regions[i][k]+", ");
}
System.out.println();
}
}
}
