Autoboxing and Unboxing in Java

Before comprehension autoboxing and unboxing in java, we should recognize what is wrapper class. So let’s investigate it.

Wrapper Class

A wrapper class folds over a crude information type and gives it an article appearance.

This wrapper class article can be utilized at whatever point the crude information type is required as an item.

Autoboxing in Java

The way toward changing over crude information type into wrapper

class object naturally is known as autoboxing. This element was included in JDK 1.5.

The model for autoboxing is given beneath. Till JDK 1.4 we

need to physically do the transformation of crude information type into a wrapper class

also, the other way around utilizing wrapper class technique yet from JDK 1.5 it is finished naturally.

Till JDK 1.4

int x=10;
Integer i=new Integer(x);  //boxing

From JDK 1.5

int x=10;
Integer i=x;         //autoboxing

Unboxing in Java

The way toward changing over wrapper class object into

crude information type naturally is called unboxing.

Till JDK 1.4

int x=10;
Integer i=new Integer(x);   //boxing
int z=i.intValue();         //unboxing

From JDK 1.5

int x=10;
Integer i=x;         //autoboxing
int z=i;             //unboxing

A rundown of crude information type with their comparing
