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

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

Solution

  • 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.
