This can be achieved by using nested loops and calculatingly adding spaces and stars as shown in the logic below:
public class InterviewBitPyramid{
public static void printPyramid(int n) {
for (int i=0; i<n; i++){ // for number of rows
for (int j=n-i; j>1; j--) {
System.out.print(" "); //print space
}
//for number of columns
for (int j=0; j<=i; j++ ) {
System.out.print("* "); // print star
}
//end-line after every row
System.out.println();
}
}
public static void main(String args[]){
printPyramid(5); //Print Pyramid stars of 5 rows
}
}
Output:
