Java Program to Print
Double Triangle Number Pattern - 1

Last Updated: 19 July, 2022

On this tutorial page, we are going to learn how to write a Java program to print the double triangle number pattern.

A pattern program is composed of two or more loop statements and print statements.

Let's see the Java Program Implementation.

Program: Double Triangle Number Pattern Program in Java

  public class Pattern18 {
    public static void main(String[] args) {
      int row, column, numberOfRows = 5;
  
      // outer loop for number of rows
      for (row = 1; row <= numberOfRows; row++) {
        // inner loop for number of columns
        for (column = 1; column <= numberOfRows; column++) {
          if (column <= row)
            System.out.print(column);
          else
            System.out.print(" ");
        }
        // inner loop for number of columns
        for (column = numberOfRows; column >= 1; column--) {
          if (column > row)
            System.out.print(" ");
          else
            System.out.print(column);
        }
        // line break
        System.out.println();
      }
    }
  }

Output

That's all guys, hope this Java Program is helpful for you.
