109.1.. Učitati dvodimenzionalni niz i formirati drugi čiji je opšti član: y_i,j = x_i,j za i+j parno, inače je y_i,j = 2.

Listing programa:

package zad1;
import java.util.Scanner;
public class P10912024 {

	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);

		System.out.print("unesi broj redova i kolona");

		int n = input.nextInt();
		int m = input.nextInt();
		int x[][] = new int[n][m];
		System.out.print("unesi clanove niza x");

		for (int i = 0; i < n; i++) {
			for (int j = 0; j < n; j++) {
				x[i][j] = input.nextInt();
			}
		}

		int y[][] = new int[n][m];
		for (int i = 0; i < n; i++) {
			for (int j = 0; j < n; j++) {
				if ((i + j) % 2 == 0)
					y[i][j] = x[i][j];
				else
					y[i][j] = 2;
			}
		}

		System.out.println();

		for (int i = 0; i < n; i++) {
			for (int j = 0; j < m; j++) {
				System.out.print(x[i][j] + " ");

			}
			System.out.println();
		}
		System.out.println();
		for (int i = 0; i < n; i++) {
			for (int j = 0; j < m; j++) {
				System.out.print(y[i][j] + " ");

			}
			System.out.println();
		}
	}
}
