Autoboxing and Unboxing

The Autoboxing and Unboxing was released with the Java 5.

Autoboxing

During assignment, the automatic transformation of primitive type(int, float, double etc.) into their object equivalents or wrapper type(Integer, Float, Double,etc) is known as Autoboxing.

Ex:

Integer intObject = 5; // autoboxing

auto-unboxing

During assignment or calling of constructor, the automatic transformation of wrapper types into their primitive equivalent is known as Unboxing.

Ex:
int inative = 0;
inative = new Integer(5); // auto-unboxing

Autoboxing also works with comparison
int a = 10;
Integer b = 10;
System.out.println(a==b); // true

How to create read only List, Map and Set in Java

// creating List in Java
List<String> names= new ArrayList<String>();

// initializing List in Java
names.add("Raja");
names.add("Ramesh");
names.add("Ramu");

Set<String> readOnlySet = new HashSet<String>(names);

//Set is not yet read-only you can still add elements into Set
readOnlySet.add("Ravi");
//making Set readonly in Java - no add remove or set operation permitted
readOnlySet = Collections.unmodifiableSet(readOnlySet);

//trying to add element in read only Set - java.lang.UnSupportedOperationException
readOnlySet.add("You can not add element in read Only Set");

//trying to remove element from read only set
readOnlySet.remove("Ramu");

//you can not remove elements from read only Set

Map<String, String> agesmap = new HashMap<String, String>();
agesmap.put("raja", "24");

//Map is not read only yet, you can still add entries into
agesmap.put("ramesh", "22");

System.out.println("Map in Java before making read only: " + contries);

//Making Map read only in Java
Map readOnlyMap = Collections.unmodifiableMap(agesmap);

//you can not put a new entry in read only Map in Java
readOnlyMap.put("ra", "33"); //java.lang.UnSupportedOperation

//you can not remove keys from read only Map in Java
readOnlyMap.remove("raja"); //java.lang.UnSupportedOperation
