Saving values into array in java

Question

for(int i=0;i<10;i++)
{
    if((i%2)==0)
    {
         System.out.println(i);
    }
}

In the above coding instead of printing "i" values I need to save the values of "i" in array. How can I save the values in an array??

Answer 1

int[] arr=new int[10];
int j=0;    

for(int i=0;i<10;i++)
{
  if((i%2)==0)
  {
     arr[j]=i;
     j++;
  }
}

Answer 2

You can declare an array like int a[10]; and then simply add the i value to the array by doing

a[1] = i;

Answer 3

Declare array and assign value to it.

int a[] = new int[10];

for(int i=0;i<10;i++){
   if((i%2)==0){
       a[i] = i;
   }
}

Answer 4

You have to declare an Array with the length of your for loop divided by 2 , as you getting the Reminder of the value of i/2 which will give you half of the values of i :

int length = 10;
int arr_i[] = new int[(int)(length/2)];
int index = 0;
for(int i=0;i<length;i++)
{
  if((i%2) == 0){
    arr[index] = i;
    index ++;
  }
}
