Examples of java.util.ArrayList.trimToSize()

java.util.ArrayList.trimToSize()
Trims the capacity of this ArrayList instance to be the list's current size. An application can use this operation to minimize the storage of an ArrayList instance.

        while ((tempElement = decodeInputStream(dbis, nesting+1, internKeys)) != null) {
            //add the element
          tempList.add(tempElement);
        }


        tempList.trimToSize();
        dbis.mark(Integer.MAX_VALUE);
        tempByte = dbis.read();
        dbis.reset();
        if ( nesting > 0 && tempByte == -1 ){
