Hello please help me ?? When i run this code in solo learn app the input option is coming but how to take array input ..

Question

import java.util.Scanner;
class Dcoder
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int arr[]=new int[n];
for(int i=0;i<=n;i++)
arr[i]=sc.nextInt();
for(int k=0;k<=n;k++)
System.out.println(arr[k]);
}
}

Answer 1

I don't have WA, besides, sharing personal information is not allowed here, it is against privacy policy. I ran that code in Code Playground, and with the for loops condition fixed, it runs OK, you can post the error message here btw ...

Answer 2

import java.util.Scanner;

class Dcoder
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int arr[]=new int[n];

// previously: for(int i=0;i<=n;i++)
for(int i=0;i<n;i++)
arr[i]=sc.nextInt();

// previously: for(int k=0;k<=n;k++)
for(int k=0;k<n;k++)
System.out.println(arr[k]);
}
}

Please read the comments over the for loops, you only needed to change the <= into < as I had shown you in my first response.

Answer 3

Enter the numbers in different lines, separated by new line (Enter), example:

100
200
300
400
500

P.S. Your loops need corrections, an array of <n> elements are indexed from 0 ~ <n> -1. If you do "i <= n" you will get array subscription error, because it tries to reference arr[<n>] which is not allocated/accessible.

for(int i = 0; i < n ; i++)

for(int k = 0; k < n ; k++)

Answer 4

some error is coming after separating in new line

Answer 5

please run in solo learn app

Answer 6

Yes, the error is triggered by the fault in the loops, as I had shown you above, change the for loops as I suggested and you'll have your code running just fine : )

Answer 7

please send me the complete code you have run successfully

Answer 8

send me your whatsapp number ... what type of error is coming I will send you
