Basic of Nested Loop and Patterns In java Using While Loop

 Question 1: Write a java programming to print basic SOLID NESTED LOOP .
Ans: About NESTED LOOP Java (aur bhi programming languages mein) mein, "nested loop" ek aise programming concept hai jahan ek loop doosre loop mein sthit hota hai. Yani ki, ek loop ke andar doosra loop hota hai. Isse, aap multiple levels ki iteration (repeatition) accomplish kar sakte hain.

Here I'm going to use for while loop to create SOLID NESTED LOOP.

First While Loop=======

package HelloWorld;

import java.util.Scanner;

public class LearningJava {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

yaha Hamne Scanner class bna liya hai 

Step2: int n = scan.nextInt();

yaha ham sabse phle user se input le rhe int n ka use krek.

step 3: int i =1;

 Iska mtlb hai ham int i naam ka row le rhe jo ki initialize/start hoga 1 se 

step 4: while (i<=n){

}

yaha ham ek while loop le rhe aur ise termination operator bna rhe jo ki i<=n hai, mtlb row hamara i hai jo ki "n" [user ke number input] se kam tk ya barabar tk chlega

step 5: int j=1;  

yaha ham column ke liye / ith row ka integer le rhe jiska name hamne j rkha hai ise ham first wale loop ke curly bracket ke andar hi rkhenge.

step 6:row wale loop ke andar rh kar hi ek aur loop lenge 

while (j<=n){

System.out.print("*");

 isme while loop ke saath j<=n rkha hai jiska mtlb hai , user ke diye gye input ke barabar hi column v print hoga aur usi ke anusar increment hoga yaani agr user ne 5 number input diya hai to row 5 aur column 5 ek sath print hoga .

end me system.out.print("*") aseterisk rkha hai jisse start print hoga ek line me row me

step 6: j wale loop ka bracket khtm hone ke bad ek aur println ka statement likhenge jisse next line milega aur nextline me print hoga 

bracket end ke bad println isliye lga rhe taaki ye clear ho ske ki ham first wale row wale loop ke liye print ka statement lga rhe 

System.out.println(); 

step 7 : ab ham sabhi ko update operator de rhe jaise first wale row i wale while loop me j loop ka statement /integer start hone se phle hi i++ lga denge aur star print statement ke phle j loop ka j++ update lga denge 

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();

int i =1;

while (i<=n){

int j=1;

while (j<=n){

System.out.print("*");

j++;

}

System.out.println();

i++;

}

}

}

kuch is trh ka programming language hota hai while loop se solid nested loop print krne ke liye
