Triangle pattern program in java:
In this tutorial we will discuss how to print a Triangle pattern in java by using Scanner class in java.
import java.util.Scanner;
class Top
{
int i,j,k,n,c=100;
public void getData()
{
System.out.println("enter a number");
Scanner sc=new Scanner(System.in);
n=sc.nextInt();
}
public void logic()
{
for(i=1;i<=n;i++)
{
for(j=1;j<c/2-i;j++)
{
System.out.print(" ");
}
for(k=1;k<=i*2-1;k++)
{
System.out.print("*");
}
System.out.print("\n");
}
}
}
class Sample
{
public static void main(String[] args)
{
Top a=new Top();
a.getData();
a.logic();
}
}
output:
