Java - Wrapper Classes

Which of the following is the correct syntax to convert an int primitive to an Integer object?

AInteger obj = Integer.parseInt(intValue);

BInteger obj = Integer.valueOf(intValue);

CInteger obj = new Integer.parseInt(intValue);

DInteger obj = intValue.toInteger();

Step-by-Step Solution

Solution:

Step 1: Identify correct method to convert int to Integer object
Integer.valueOf(intValue) returns an Integer object from int primitive.
Step 2: Check syntax correctness of options
Integer.parseInt returns int primitive, not Integer object. new Integer.parseInt is invalid syntax. intValue.toInteger() is invalid because int is primitive.
Final Answer:
Integer obj = Integer.valueOf(intValue); -> Option B
Quick Check:
int to Integer object uses valueOf [OK]

Quick Trick: Use Integer.valueOf to box int to Integer object [OK]
