These three steps succinctly illustrate the conversion of anintto anIntegerusing auto-boxing in Java. Output: Primitive int: 42Converted Integer: 42 The output confirms that the auto-boxing process successfully converted theintprimitive to itsIntegerequivalent, highlighting the effectiveness of this appr...
