java.lang.ArrayStoreException at java.lang.System.arraycopy(Native Method)

Question

int toSize=toMailIds.size();
InternetAddress[] address=new InternetAddress[toSize];
address=toMailIds.toArray(address);

Here toMailIds is arraylist.

I am getting the following exception.

java.lang.ArrayStoreException

it seems like your toMailIds list does not contain elements of type InternetAddress — Philipp Sander

toMailIds is nothing but list of strings .InternetAddress will accept Strings — Kranthi Sama

You are going to have to use a loop in this case:

int toSize=toMailIds.size();
InternetAddress[] address=new InternetAddress[toSize];

for (int i = 0; i < toSize; i++) {
    address[i] = new InternetAddress(toMailIds.get(i));
}

If a list stores Strings, the toArray method will not create InternetAddress objects from them automatically.

address=toMailIds.toArray(); is enough here. But type of address array should be Object[]

Example

List<String> list=new ArrayList<>();
Object[] atr=list.toArray();

toArray() returns Objects and address it of type InetAddress. this will not compile
