Example:

When number of  rows : 5

0      0
0      0
00000
1      1
1      1
11111
2      2
2      2
22222
3      3
3      3
33333
4      4
4      4
44444
5      5
5      5

Now, let’s see the actual program printing it.

Are you wondering how to seek help from subject matter experts and learn the Java language? Go with these Basic Java Programming Examples and try to code all of them on your own then check with the exact code provided by expert programmers.

Approach:

Enter total row and store it in an integer variable row.
Take first for loop to print the row value and number for each row.
For each iteration print 2 side numbers.
And for each condition (r<row) print the stair bar.
Then go on printing the numbers according to loop.

Java Code to Print Ladder Number Pattern

import java.util.*;
public class Main 
{    
    public static void main(String args[])   
    {   
    // taking variable for loop iteration and row .
    int row,r;
    //creating object 
    Scanner s = new Scanner(System.in);
    // entering the number of row
    System.out.print("Enter rows : ");
    row = s.nextInt();
    //outer for loop 
    for ( r = 0; r <= row ; r++)
    {
          // Printing the sub-pattern 1 row+1 times
        System.out.println(r+"   "+r);
        System.out.println(r+"   "+r);
        // Printing the sub-pattern 2 row times
        if (r < row)
            System.out.println(r+""+r+""+r+""+r+r);
    }
  }
}

Output:

Enter rows : 5

0      0
0      0
00000
1      1
1      1
11111
2      2
2      2
22222
3      3
3      3
33333
4      4
4      4
44444
5      5
5      5

C++ Code to Print Ladder Number Pattern

#include <iostream>
using namespace std;
int main()
{
   int row, r , c ,d ;
   cout << "Enter  rows: ";
   cin >> row;
   for ( r = 0; r <= row ; r++)
    {
        cout << r<< "   " << r ;
        cout << "\n" ;
        cout << r<< "   " << r ;
        cout << "\n" ;
        if (r < row)
            cout << r<<r<<r<<r<<r ;
            cout << "\n" ;
    }
   return 0;
}

Output:

Enter rows : 5

0      0
0      0
00000
1      1
1      1
11111
2      2
2      2
22222
3      3
3      3
33333
4      4
4      4
44444
5      5
5      5
