You need to work around for this :

Using with Arrays.copyOf

item =  Arrays.copyOf(itemtypes , itemtypes.length + 1);
item[item.length - 1] = "RFID";

Or direct split from Koradcnos

item = (Koradcnos + ";RFID").split(";");

itemtypes is String array,it can't be modified,if you want to get a new array adding another element,you can use System.arrayCopy

System.arraycopy(Object src,  
             int  srcPos,
             Object dest, 
             int destPos,
             int length)

Like this:

item = new String[itemtypes.length+1];
System.arraycopy(itemtypes,0,item,0,itemtypes.length);
item[itemtypes.length] = "RFID";

You cannot concatenate string with a list String.split() method returns a String array.

Instead of item=itemtypes+"RFID" iterate through the array as:

for (int i=0; i < itemtypes.length();  i++) {
    item[i] = itemtypes[i] + "RFID";
}

Also I think the variable name will be itemtypes instead of itemtype
