HackerRank : StairCase

Your teacher has given you the task of drawing a staircase structure. Being an expert programmer, you decided to make a program to draw it for you instead. Given the required height, can you print a staircase as shown in the example?
Input
You are given an integer N depicting the height of the staircase.
Output
Print a staircase of height N that consists of # symbols and spaces. For example for N=6, here's a staircase of that height:
     #
    ##
   ###
  ####
 #####
######
Note: The last line has 0 spaces before it.

public class Solution {



    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);

        int n = in.nextInt();

        for(int i=0;i<n;i++){

            for(int j=1;j<=n;j++){

                System.out.print(j<n-i?" ":"#");

            }

            System.out.println();

        }

    }

}


Sample Input:
6

Sample Output:
          #
        ##
      ###
    ####
  #####

Handling Performance Bottlenecks in Spring Applications

Problem: Many developers encounter performance bottlenecks in their Spring applications due to inefficient database queries, improper caching, and suboptimal resource management. These bottlenecks can lead to slow response times and a poor user experience. Solution: This blog post explores strategies for identifying and resolving performance bottlenecks in Spring applications. 1. Profiling and Monitoring We can use tools like Spring Boot Actuator, VisualVM, or JProfiler for profiling Spring applications. Sample : Example configuration to enable Spring Boot Actuator: @SpringBootApplication public class MyApplication { public static void main (String[] args) { SpringApplication.run(MyApplication.class, args); } } 2. Optimizing Database Queries W riting efficient SQL queries and using pagination to handle large datasets. Sample : Example of using pagination with Spring Data JPA: @Repository public interface UserRepository extends JpaRepository <User, Lon...

Retry in SprinBoot Application

In a Spring Boot application, you can use the @Retryable annotation to automatically retry a failed operation. The @Retryable annotation can be applied to a method and can be used to specify the conditions under which the method should be retried. For example: @Retryable (value = { MyException. class }, maxAttempts = 3 , backoff = @Backoff (delay = 1000 )) public void myMethod () throws MyException { // method body } In this example, the myMethod() method will be retried if it throws an exception of type MyException. The method will be retried up to a maximum of 3 times, with a delay of 1000 milliseconds between each retry. You can also specify the @Recover annotation on a method to provide a recovery action for a failed operation. The @Recover method should have the same signature as the retryable method, except that it should have an additional parameter of type Throwable to receive the exception that caused the failure. For example: @Recover public void recover (MyE...
