my final is around the corner, thanks for making these videos, its awesome, HELPS ALOT!! THANK YOU

[sutriptimnath]

for(int i=0; i<size; i++) {
System.out.print(grade[i] + ", " )
}

[LimeWitness]

Instead of int x = input.nextInt();
grades[i] = x;


You could just do grades[i] = scanner.nextInt();

[zahraxhamzah]

for (int i = 0; i < size; i++) {

}

[mauriceallenliddy]

for(int i = 0; i < size; i++) {
System.out.print(input[i] + " ");

}


hooray! And thanks so much Caleb. I've watched all videos so far. You're really helping me get a head start before I start a software development course next month.

Hey, thanks for making these vids, helps ALOT!

[muhammadsyamsul]

thanks! very helpful, my assignment is finished :)

Firstly, this is great content. Thank you for these videos!!!

I added some statements to aks for input. Also, I used grades.length to print out the array using a for loop.
Not sure if it's the best option.

import java.util.Arrays;
import java.util.Scanner;



public class MySweetProgram {

public static void main(String[] args) {
System.out.println("Choose the size of the Array.");
Scanner input = new Scanner(System.in);
int size = input.nextInt();
int[] grades = new int[size];

for(int i = 0; i < size; i++) {
System.out.println("Insert a digit.");
int x = input.nextInt();
grades[i] = x;
}

for(int k = 0; k < grades.length; k++) {
System.out.print(grades[k] + " ");
}

}
}

For the solution to the last part, I put the last statement within the for loop and it's printing each element as it's added to the array.
Not sure if this was what you wanted us to do, if not could you please explain.

Finally A video with 0 dislike. He deserves it too.

[Lutscherstange]

Had to actually look it up... forgot to put corner brackets around i

-> will give you that value of the arraynumber based in the run-variable from the For-loop

[elmua]

what about if you create a array directly from user input. Like read number to array until user input negative number (positive numbers should be the size of array). How this works?

[TechJoltd]

for outputting array without using the toString I did:

public static void arrayToString(int[] Array) {

for(int i = 0; i < Array.length; i++) {
if(i == (Array.length - 1)){

System.out.println(Array[i]);

} else {

System.out.printf(Array[i] + ", ");

}
} 
} //End of arrayToString


And in my main method:
arrayToString(grades);
I guess I'm a bit late to this.

I was wondering is it possible to use it in string arrays?

[ShawnJeezie]

on windows it lets me input integers but doesn't show anything, and it only has a yellow underline under our name for the scanner. when hovering over it, it says scanner cannot close.

[nanaarhin]

Hi, I know its been years since you did this video and I am now learning java. Can you explain why line 13 is there and what is does. Please

[tatimore]

how do you do loop for names like usernames?

[a_nurulasyiqin]

Caleb! I want to ask you questions can i email to you?

[herevancelightena]

What about ArrayList with a for loop user input!!!!

[BaconAndMinecraft]

Why don't you use sout instead fo sysout?
