Collections.checkedSortedMap(SortedMap, Class, Class) in Java

Collections.checkedSortedMap(SortedMap, Class, Class): This method is available in java.util.Collections class of Java.

Syntax:

<E1, E2> SortedMap<E1, E2> java.util.Collections.checkedSortedMap(SortedMap<E1, E2> m, Class<E1> keyType, Class<E2> valueType)

This method takes three arguments. This method returns a dynamically typesafe view of the specified sorted map.

Note: Any attempt to insert a mapping whose key or value has the wrong type will result in an immediate ClassCastException.

Parameters: Three parameters are required for this method.

m: the map for which a dynamically typesafe view is to be returned.

keyType: the type of key that m is permitted to hold.

valueType: the type of value that m is permitted to hold.

Returns: a dynamically typesafe view of the specified map.

Exceptions: NA

Approach

Java

import java.util.Collections;
import java.util.SortedMap;
import java.util.TreeMap;

public class CollectionscheckedSortedMap {
    public static void main(String[] args) {

        SortedMap<String, Integer> sortedMap = new TreeMap<String, 
                                                       Integer>();

        sortedMap.put("Hello", 78);
        sortedMap.put("Java", 23);
        sortedMap.put("Abc", 24);
        System.out.println(Collections.checkedSortedMap(sortedMap,
                                   String.class, Integer.class));

    }
}

Output:

{Abc=24, Hello=78, Java=23}
