Answer 1

import java.util.Random;
import java.util.Scanner;

public class Array2d {

   public static void display(int a[][]) {
       for (int i = 0; i < a.length; ++i) {
           System.out.println();
           for (int j = 0; j < a[0].length; ++j) {
               System.out.print(a[i][j] + " ");
           }
       }
   }

  
   public static void tConverted(int t[][]) {
       for (int i = 0; i < t.length; ++i) {
           for (int j = 0; j < t[0].length; ++j) {
               if(t[i][j] < 0)
                   t[i][j] = -1;
               else if(t[i][j] > 0)
                   t[i][j] = 1;
                     
           }
       }
   }
   public static void main(String[] args) {
       // TODO Auto-generated method stub

       int row, cols, row1, col1;
       Scanner sc = new Scanner(System.in);
       System.out.println("Enter number of rows: ");
       row = sc.nextInt();
       System.out.println("Enter number of cols: ");
       cols = sc.nextInt();

       Random r = new Random();

       for (int i = 0; i < row; ++i) {
           for (int j = 0; j < cols; ++j) {
               a[i][j] = r.nextInt(100) - 50;
           }
       }
       System.out.println("Original Matrix ");
       display(a);
      
       tConverted(a);

      
       System.out.println("\nAfter T converted ");
