Understanding the concepts clearly please keep uploading videos

Multidimensional Array concepts please

[mohammedasif]

the concept is very helpful Do programs on second largest number in array

wrong method you have taken fixed values which give a and b become same what if a is 42 b is 16

import java.util.Scanner;

public class GCD {

public static void main(String[] args) {
Scanner scan =new Scanner(System.in);
System.out.println("enter first number");
int n1 =scan.nextInt();
System.out.println("enter second number :");
int n2=scan.nextInt();

if(n1==0) {
System.out.println("GCD is: "+n2);

}
else if(n2==0) {
System.out.println("GCD is :"+n1);
}

while(n1!=n2) {
if(n1>n2)
{
n1=n1-n2;
}
if(n1<n2) {
n2=n2-n1;
}
}
if(n1==n2) {
System.out.println("GCD of n1 and n2 is : " +n1);
}
}
}
here is the correct format of the code

Bro you declared String but you stored integer . please first learn then teach ..
