Nested For Loop In Java Tutorial #24

The nested for loop in java is just a for loop inside of a for loop. A common way to use a nested for loop in java is to get elements from a 2d array. To do that, your outer for loops takes care of the rows and your inner for loop takes care of the columns.

Java loops can be VERY tricky, but don't worry too much about it right now! Use the code I provided and after time you'll get the hang of java loops :) If you followed along, congrats! You learned-by-doing!

I hope you enjoyed this nested for loop in java tutorial! I like to have a nice mix of tutorials and actual projects for you all :)

How are you using nested for loops in java? -

I didn't pay attention in my java class and now this guy saved my life

[PeanutButter]

This guy the GOAT, best tutorials I've seen

If you have an array with different dimmensions try:
for(int i =0; i< array.lenght; i++) {
for(int j =0; j< array[0].length; j++) {
}
}
This will go through all values in array that is or isnt square

Alex, people like me need your videos! Whenever I am confused about anything or need an explanation I can understand I can always count on you. Please never stop making videos!

I had no idea what we were doing in class today, thanks for the help!

Thanks for explaining clearly, this nested is so hard for me at starting 2 months at coding. Nested and array are so difficult.

Man, I really was blown away by this amazing tutorial on nested loops! It's sooo damn good! Also I love how easy you explained how to use it to print 2D arrays.
Thank you so so much! 🥰

Good thing i ran to your videos while learning java, the old concept i learned in cpllege are now cleaner, good job Alex.

[dokadoki]

Ah im telling you im gonna fall in love with this guy HAHA
What a life saver hahaahsha thanks man!

Great vid! Super helpful! You are awesome!

Since you asked, I'm learning about nested for loops because they're one of the key concepts to get your head around if you want to reach a higher level of programming (in my opinion).

Furthermore, I would say that nested for loops and nested while loops open up a lot more possibilities - so thanks a lot for this very explanatory video!

Myself in APCSA class, first time student come from India to US of A, my first teacher Sridhar Kandukari very smart man, he help me now u teach me, very nice sir, vineeth kandukuri also likes ur teachigg always watches video with fav lemon pickle recipe from vah chef

[rittenbrake]

hey I think u teach better than others, esp in explaining the nested loops topic, listing all i and j

I'm using it for an assingment, this really gave me the basis of Nested For Loops. I'm using to create the infamous create words out of phone numbers ie: 2 = ABC, so there is about 2143 different combinations for a 7 digit phone number, and I'm going to use for loops to help with this, I hope. Almost forgot the 2D arrays video also helped in using [ ][ ]{"A", "B", "C"}, {"D ", "E ", "F "}, etc. Thank you again!

This videos are incredible! I cannot understand what my Java teacher says for the life of me but this makes so much sense! Thank you!

I'm using nested for loops for a class assignment. We are given a number of rows and columns. Rows are integers and columns are alphabetical. so the output should list something like this //row1 1A 1B 1C //row2 2A 2B 2C and so on. Pretty difficult for an online class but your videos help a lot. Thanks!

[mingchen]

It's good, easy to understand. Thanks!

[sayed.ahmadmosavi]

i recently start learning java online to get a job, i do have teacher to teach me but i never understand what he is saying till, but the good things i found your videos on youTube and your way to teach is amazing, you are amazing.

Making for loops to find perfect numbers from 1-10000 First intro programming class this shit helped a lot

[lake]

This guy is literally teaching me Java more the paid courses very good explaining and makes everything simple a lot of people owe this guy honestly !!

[serdargayibov]

Thank you so much! It breaks down simple concepts for easier understanding
