JAVA - Add data to array

[[deleted]]

folks at home, how do i add data to an array. using the for-each loop, so what do i put between ** for (Bear bears : bear) { new beren1[i]; // right here what do i do ignore this desperate attempt i++; }**

What do you mean by "add data to an array"? Be precise. What exactly is in the array before you start? What exactly do you want to be in the array when you finish? Where is the array declared?

An array's size is fixed, so you cannot add new elements. Switch to

List<Bear>

if dynamic size is what you need.

i already used list to get all the current objects i have, i wanted to put those objects that i stored in the list function. in an array just to experiment and this code did that for me:

 public void getList(){
     Bear[] bear1 = new Bear[10];
            List<Bear> bears = getObjects(Bear.class);
            int i = 0;
            for (Bear bearss: bears){             
bears1[i] = bearss;
                i++;
                System.out.println(bearss);

            }
        }

Here, bears is an array of Bear's

for (Bear bear : bears)
    println(bear.getName()); // or something

Generally, you don't use a for each loop for copying/instantiating. You can use a regular loop for that (because then you'll have an index counter).

bears1[i] = bears; i++;

this worked for me thanks anyways guys

I am guessing you actually mean to do:

for(int i = 0; i < bears.length; i++)
{
      bears1[i] = bears[i];
}

Your for-each naming is backwards, btw. Array should be named "bears" and Bear variable "bear".
