This is blank not showing output why ?

Question

package arr;

public class Alar {
public static void main(String[] args)
{
int arr[]= {10,20,30,40,50};

int n=5;
other.find(arr,n);

}
}

class other {
static void find(int arr[],int n) {

int temp=arr[n-1];

for(int i=0;i<=n-2;) {
arr[i]=arr[i+1];
}

arr[n-1]=temp;

for(int i=0;i<n;i++) {
System.out.print(arr[i]);
}

}

}

This is not showing any output

input 10,20,30,40,50
output will be 20,30,40,50,10

Answer 1

what is the purpose of the first line? it makes java not recognizing your classes: you must remove it ^^

the 'find' method of 'other' class lacks of i incrementation in first loop...

you are assigning the same value to 'temp' than the one you assign from temp after second loop: 'temp' should be initialized with arr[0]...

your second loop lacks of comma separator outputed after each values except the last...

working code:

public class Alar {
public static void main(String[] args)
{
int arr[]= {10,20,30,40,50};

int n=5;
other.find(arr,n);

}
}

class other {
static void find(int arr[],int n) {

int temp=arr[0];

for(int i=0;i<=n-2;i++) {
arr[i]=arr[i+1];
}

arr[n-1]=temp;

for(int i=0;i<n;i++) {
System.out.print(arr[i]);
if (i<n-1) System.out.print(",");
}

}

}

however, you doesn't take input from user but hardcode the array used ;P

Answer 2

couldn't explain more briefly than what I do previously ^^

Answer 3

I didn't understand explain briefly

Answer 4

You have 2 error

1 bad temp initialization
2 do not increment i in the for cicle (infinite loop)
