Issue
I have a question about Java. I have an Object[]
(Java default, not the user-defined) and I want to convert it to a String[]
. Can anyone help me? thank you.
Solution
this is conversion
for(int i = 0 ; i < objectArr.length ; i ++){
try {
strArr[i] = objectArr[i].toString();
} catch (NullPointerException ex) {
// do some default initialization
}
}
This is casting
String [] strArr = (String[]) objectArr; //this will give you class cast exception
Update:
Tweak 1
String[] stringArray = Arrays.copyOf(objectArray, objectArray.length, String[].class);
Tweak2
Arrays.asList(Object_Array).toArray(new String[Object_Array.length]);
Note:That only works if the objects are all Strings; his current code works even if they are not
forTweak1 :only on Java 1.6 and above
