[@Ceyhus]

Great! Thank you!!!

[@manognamanu24]

Sir ur explanation is very useful..
When u will upload pythan clases sir

[@milanvirendra8881]

Scanner milan = new Scanner(System.in);
System.out.println("Select the size of the array");
int n = milan.nextInt();
System.out.println("Select a number between 1 & 20");
int nr = milan.nextInt();
if(n

[@wesjales5578]

The first example is great for a beginner to understand.
The second example is too complicated.

[@kevinbanan]

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Write how many numbers you wanna fill the array with:");
int n = sc.nextInt();
if (n 0) {
int[] arr = new int[n];
fill(arr);
System.out.println("These are the contents");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i]);
}
}
}
static int[] fill (int[] arr) {
Scanner sc = new Scanner(System.in);
for(int i = 0; i < arr.length; i++) {
System.out.println("Write a number:");
int n = sc.nextInt();
arr[i] = n;
}
return arr;
}

[@acunit5627]

Scanner s = new Scanner(System.in);
System.out.println("Enter how large you want this array from 1 - 20");
int a = s.nextInt();
while (a < 1 || a > 20) {
System.out.println("Please enter an integer between 1-20");
a = s.nextInt();
}
int[] array = new int[a];
System.out.println("Enter what integer you want to fill in this array");
Arrays.fill(array, s.nextInt());
System.out.println(Arrays.toString(array));

Instead of OR operator can we use AND operator. If so, what happens?

[@sahayaarulanandageethans5443]

Im using eclipse for java programming. In eclipse the (toString) not working. Can you help me with this ?

Enn thalivan da nee..

[@t.lakshmiprasanna8355]

It is showing an error as (point cannot be resolved as a type)...if we try with point[] in eclipse..can u pls help with it

[@racecarguy21]

how to create the method class in VS code as shown above by using alt and enter?

[@kalyansandeep878]

why should we print the array using 'Arrays' class? How do I print without using the arrays class?

[@cosmiccreativity7731]

you have to use the loop method then...Otherwise it will not print the elements of the array instead will print the address of the array

[@cherryblossom4889]

Is it possible to solve this without using methods??

[@SomnathPattnaik]

Definitely it's possible

[@manikandana9368]

Sir, I have one doubt. I cannot able to use Point in Online GDB compiler sir. Can you explain me how to resolve that error. It shows that "cannot able to find the symbol point" while compiling the program. What is the Error?

[@X_y_zaid]

You need to import class Point from Package awt

[@fethiocalan_1]

import java.util.Arrays;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
//enter number from 1 to 20// fill the array.
Scanner input = new Scanner(System.in);
System.out.print("how many value do you want to add : ");
int add = input.nextInt();
if (add >= 1 && add

[@ferhatf9385]
