LOOPS QUESTION PRACTICE | PRACTICE SERIES 002 | A JAVA JOURNEY BY DIVYANSHU KHARE

Question: Write a Java program to print numbers from 1 to 10 using a for loop.
Ans: 

package HelloWorld;

public class LearningJava {

public static void main(String[] args) {

for (int i = 1; i < 11; i = i+1){

System.out.println(i);

}

}

}

yaha hamne kya kiya hai for loop liya hai aur bracket me integer i liya hai , kyu ki question me 1 se print krne ko kaha gya hai to initialization me i = 1 hamne rkha hai, kyon ki 1 se start krna hai , next hamne i < 11, likha hai iska mtlb ye ho rha 11 tk jake hamara ye loop statement stop ho jayega lekin 11 < se kam 10 tk hi print hoga , iske bad hamne i = 1+1 likha hai jiska mtlb ho rha i ke value ke sath ham 1 add krte ja rhe jisse 1 se 1 add hoke 2 ho rha .


at the end hamne println krke statement print kr diya hai ..


Question02: Write a Java program to print the multiplication table of a given number using a for loop.

Ans:

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 <= 10; i++) {

int sum = n*i;

System.out.println(sum);

}

}

}

Yaha pe hamne <= lagaya hai jiska mtlb hota hai ye tab tk print krega jab tk ki 10 se niche na ho aur 10 ke barabar na ho
