In JDK 1.5, analyze the following code.

Line 1: Integer[] intArray = {1, 2, 3};
Line 2: int i = intArray[0] + intArray[1];
Line 3: int j = i + intArray[2];
Line 4: double d = intArray[0];

◦ Line 4 is OK. An int value from intArray[0] object is assigned to a double variable d.
◦ It is OK to automatically convert an Integer object to an int value in Line 2.
◦ It is OK to assign 1, 2, 3 to an array of Integer objects in JDK 1.5.
◦ It is OK to mix an int value with an Integer object in an expression in Line 3.
