6.11 Enhanced for Loop with 2D Array

The enhanced for loop was introduced in Java 5 as a simpler way to iterate through all the elements of a Collection (Collections are not covered in these pages). Enhanced for loops are simple but inflexible. They can be used when you wish to step through the elements of the array in first-to-last order, and you do not need to know the index of the current element. In all other cases, the "standard" for loop should be preferred.

Thank you so much! This helped me understand how to traverse a 2d array with enhanced for loops, now I will be more prepared for the AP test that I have to take tomorrow! 😅 thank you

[MichaelMooregrownman]

OMG I was reading a book on using the enhanced for on multi-arrays and you explained BETTER!! You broke it down very well. Thank you very much. Please keep making videos!

[prajwalgaikwad]

Perfect this channel has all answers for my "How" And "why".👍😃

[ShivamKumar-sczx]

You are a good finisher of problem solving !!

[meghashetty]

wow yu r so intellingent...yu knw hw to get into somebody's mind...all yur vedios r good :)

[shayondebroy]

very useful! I recommend this video for this particular case! will give you a better understanding!

[ramyach]

Sir yours teaching is very good. Try to upload more videos on java every topic

[archanahosamani]

Please make a video to calculate absolute difference of diagonal matrix using advanced for loop

[ahora]

A lot helped! Thanks more than a thanks!!

[hamzabohra]

Sir when in enhanced for loop i is element we declare right as "int i ", but when declaring i as arrary why we declare it normally as "int i[ ]" it should be declared as "int i[ ] = new int[]" first and then transfer array in for

[vanshikamittal]

Can we use enhanced for loop in c c++ programs??

[shaileshsingh]

sir why do u change to mac and Windows alternately?

[kunwartaneja]

How did you applied single line comment all together by selecting the reqiuired code?

[sairajdas]

Sir how are commenting the code so quickly?

[vinayvenkatesh]

Sir is it possible to use for each loop for taking input elements

[vidheesavani]

Sir can I use Random number for 2D array..?

[micky]

Heard about Vowels? Have a look. Will make your speech better and ease your listeners! Great explanation though.

[samantkumar]

can anybody please tell me why i am getting hashed values for the below code.

package pr1;

public class Arr2d {

public static void main(String[] args) {

int x[]= {5, 6, 7, 8};
int y[]= {3, 4, 1, 2};
int z[]= {0, 9, 8, 7};

int a[][]= {{5, 6, 7, 8}, {3, 4, 1, 2}, {0, 9, 8, 7}};

for(int n[] : a)
{

for(int m : n)

{ System.out.println(n);}


}
System.out.println(a[2][3]);
}

}

package javaapplication127;
import java.util.Random;
public class random_class {
public static void main(String[] args) {
Random r= new Random();
int array[][] = new int[5][8];
for (int i=0;i<5;i++)
{
for (int j=0;j<8;j++)
{
array[i][j]=r.nextInt(100);
}
}
for(int x[]:array)
{
for(int y: x)
{
System.out.print(y+" ");
}
System.out.println();
}
}
}
