Explanation:
Star Patterns in Java
First, let us begin with the basic and the commonly asked pattern program in Java i.e Pyramid.

Let’s write the java code to understand this pattern better.

public class Edureka
{
public static void pyramidPattern(int n)
{
for (int i=0; i<n; i++) //outer loop for number of rows(n) { for (int j=n-i; j>1; j--) //inner loop for spaces
{
System.out.print(" "); //print space
}
for (int j=0; j<=i; j++ ) //inner loop for number of columns
{
System.out.print("* "); //print star
}
System.out.println(); //ending line after each row
}
}
public static void main(String args[]) //driver function
{
int n = 5;
pyramidPattern(n);
}
}
