If you are in the coders world you must have a knowledge of printing patterns. In coding interview interviewer may ask you print any number pattern , alphabet pattern or an character patterns. We recommend you to follow our patterns series so you will feel comfortable with printing patterns. In this blog post you will find set 4 of star patterns.
We recommend you to solve other types patterns as well –
Click on the pattern and you will get redirected to the code.

public class MainClass {
public static void main(String[] args) {
for (int i = 0; i < 9; i++) {
for (int j = 0; j < 9; j++) {

System.out.print("*");
else
System.out.print(" ");
}
System.out.println();
}
}
}
