Ans: 

// Java me Inverted Right Triangle Pattern Print Karna

// Import karne ka statement, jisse Scanner ka use ho sake

import java.util.Scanner;

// Class ka declaration "LearningJava"

public class LearningJava {

// Main method, yahaan program ki execution shuru hoti hai

public static void main(String[] args) {

// Scanner ka object banaya gaya, jisse hum input le sakte hain

Scanner scan = new Scanner(System.in);

// User se ek integer input liya gaya

int n = scan.nextInt();

// Yeh loop n se 1 tak chalega

for(int i = 1; i <= n; i++) {

// Yeh loop n se i tak chalega

for(int j = n; j >= i; j--) {

// Har baar '*' print kiya jayega

System.out.print("*");

}

// Har baar ek new line print kiya jayega, taaki pattern sahi dikhaye

System.out.println();

}

}

}

Code: package HelloWorld;

import java.util.Scanner;

public class LearningJava {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

int n = scan.nextInt();

for(int i =1;i<=n;i++) {

for(int j=n;j>=i;j--) {

System.out.print("*");

}

System.out.println();

}

}

}

1. import java.util.Scanner;:

Yeh line Scanner class ko java.util package se import karti hai. Scanner class ka upayog user se input lene ke liye hota hai.

2. public class LearningJava {:

Yeh line LearningJava naam ki class ka declaration karti hai, jisme program ke code likhe jayenge.

3. public static void main(String[] args) {:

Yeh main method ko define karta hai, jo program ki execution ka entry point hota hai. Ismein program ka code likha jata hai.

4. Scanner scan = new Scanner(System.in);:

Yeh line ek Scanner object scan banata hai, jiska upayog console se user input lene ke liye kiya jata hai.

5. int n = scan.nextInt();:

Is line mein program user se ek integer input leta hai, jo n variable mein store hota hai. Yeh input inverted triangle pattern ka size nirdharit karta hai.

6. for(int i = 1; i <= n; i++) {:

Yeh for loop i ko 1 se lekar n tak iterate karne ke liye hota hai. Yeh panktiyon ki sankhya ko control karta hai.

7. for(int j = n; j >= i; j--) {:

Yeh doosra for loop j ko n se lekar i tak iterate karne ke liye hota hai. Isse yeh pattern ke andar stars ki sankhya ka control hota hai.

8. System.out.print("*");:

Yeh statement ek star (*) ko print karta hai, jisse pattern mein star print ho sake.

9. System.out.println();:

Yeh statement ek nayi line par jata hai, jisse har ek pankti ke baad pattern sahi dikh sake.

10. }:

Yeh curly brace for loop ko samapt karta hai, aur i ke liye agle iteration ke liye loop ko phir se shuru karta hai.

11. }:

Yeh curly brace main method ko samapt karta hai, jisse program ki execution samapt ho jati hai.

Is prakar, yeh code user ke diye gaye input ke adhar par ek ulata sahi tricorn pattern stars se print karta hai. Har ek code ki vyakhya se samajhne mein madad milegi aur aapko code samajhne mein aasani hogi.
