#29 Multi Dimensional Array in Java

[@Abbydups]

You’re such an angel! You helped me so much in understanding my homework.

[@ravinduwellalage]

ayoo ayoo

[@ayodhyarode]

Sir you teach every concept in an Amazing way. It is helping me to understand everything. Thanks a lot sir 🙏😊

[@MdKamrulIslam-lo9xn]

creating an object of the Random class could also be done here to do the job: Random random = new Random(); nums[ i ] [ j ] = random.nesxtInt(); // put the upper limit inside the nextInt bracket if you want an upper limit.

[@sarathchandar5047]

Big fan of u Navin sir … fantastic series of java … like u had for python

[@yashaswinihm4288]

Normal for loop is better and clear than enhancled for loop

[@samantsrivastava8170]

Yes

[@SanataniRishu02]

Nah enhanced for loop is much better you just have to understand that in enhanced for loop : iterates over a element in group

[@cramyboba1013]

You helped me a lot with my homeworks sir, thank you from Myanmar

[@shenbagamr421]

Nice teaching nallave puriyuthu bro❣️

[@sindhisajadali610]

Sir that's best Collection of lectures Plz share Assimignment or H. W It's easy way to students understand and do H. W

[@egor_andryushchenko]

Thank you for this lesson, I have enjoyed it a lot, reminds me of my time in university with C++.

[@GargeyasaikrishnaChava]

I think this topic is less used in daliy life purposes

[@DarkyBoy-n1i]

Yes, I do as you said after watching.

[@elikmtl]

The best explanation ever! Thank you very much.

[@aids9918]

Awesome tutorial!

broo navin bro thandani thane thane thandane thane thane noo brooo super explanation

[@mrgold8267]

Why don't we do this: Random rand = new Random(); import java.util.Random; class Main { public static void main(String[] args) { Random rand = new Random(); int[][] arr = new int[5][]; for(int i = 0; i < arr.length; ++i) { arr[i] = new int[rand.nextInt(5,10)]; for (int j = 0; j < arr[i].length; ++j) { arr[i][j] = rand.nextInt(0,10); } } for(int i = 0; i < arr.length; ++i) { for (int j = 0; j < arr[i].length; ++j) { System.out.print(arr[i][j] + " "); } System.out.println(); } } }

[@CHALLENGESTORY]

😂

[@emerald8743]

@Telusko, The main array is 3 rows and one column right? I see there is only one column for main array which has 3 arrays. The four columns are of internal arrays right?

[@sentfromheaven00]

What program do you use to draw the diagrams for us? I really like it

[@sindhunayak9354]

Who don't have laptop or desktop And practice with mobile

[@rohitpal73]

Lol 😂😂😂😂

[@kuchbhi7118]

Well my father will buy me one this diwali.. what about you did you finish java ?

[@kvelez]

import java.util.Arrays; public class Main{ public static void main(String[] args) { int[][] nums = new int[3][4]; for (int i = 0; i < 3; i++) { for (int j = 0; j < 4; j++) { int random = (int)(Math.random() * 10);//type casting nums[i][j] = random; System.out.print(random + " ");//row limit } System.out.println();//line break } System.out.println();//For each format for (int[] num : nums) { System.out.println(Arrays.toString(num)); } System.out.println();//For each format for (int[] is : nums) { for (int is2 : is) { System.out.print(is2 + " "); } System.out.println(); } } }

[@shaikbasha3882]

if you are here then i would have kissed on your head man, you just clarified all the doubts which was there from ages ..

[@manavkaneria]

What's about if we want to take input from the user?

[@praveenr7957]

I run array in vs code it gives something main error. But I run in Eclipse it gives output.

[@YoutubeCom-de9ye]

Sir pls give free coupon code for your Udemy course. It's an amazing course and your explanation it just excellent

[@nikilkandula8562]

Sir can we scanner class to intialise variables

[@The_Motobikers_World]

Yes, scanner class should be in a nested loop where outer loop represent the row no(no of array )and inner loop represent the column (no of elements in the array) . The syntax will be:- Arr[row][column]=sc.nextInt();//before that you should include the scanner class in your code and create an object of that .

[@LAVAN-2424]

sir why to take random Values teach and insert user given values.

[@adityakaushik2845]

Math.random not working in my compiler.why??

[@nikilkandula8562]

First u have to import it's library

[@AravStark]

You have to import it bro

[@lohithareddy15]

@@nikilkandula8562 how can i import math library in vs codde.....can u please help me

[@ArjunU931]

​​@@lohithareddy15 type this code in the first line ok. " import java.lang.Math; ". 😊

[@cosmesumagaysay7126]

​@@lohithareddy15import java.util.Random;

[@FahadAli-i9x]

How can we ourself initialize the multidimensional array as we do in 1d array

[@The_Motobikers_World]

Just simply assigned the value in row and column format where row represent the no of array and column represent the no of elements in the array . Just for example first array 0th element we have to write Array[0][0]=some value; Like wise that second array third element supposed the array size is of 3 Then the syntax will be Array[1][3]=some value;

[@The_Motobikers_World]

Another way scanner class should be in a nested loop where outer loop represent the row no(no of array )and inner loop represent the column (no of elements in the array) . The syntax will be:- Arr[row][column]=sc.nextInt();//before that you should include the scanner class in your code and create an object of that .

после активации бота, подскажите, как можно включить текущую сетку? не могу что то найти кнопку
