Java reducing odd triangle pattern.

 import java.util.Scanner;

class ReducingOddTriangle

{

static void reducingOddTriangle()

{

System.out.print("Enter the height of the triangle :");

Scanner sc = new Scanner(System.in);

int height = sc.nextInt();

int height_inner = height;

for(int i = 0; i<= height/2; i++)

{

for(int j = 1; j<= height_inner; j++)

{

if(j%2 != 0)

{

System.out.print(j);

}

}

height_inner = height_inner - 2;

System.out.println();

}

}

public static void main(String[] args)

{

reducingOddTriangle();

}

}
