0 votes
import java.util.*; 
import java.util.stream.*;

public class MyClass {
    public static void main(String args[]) {
        Map<Integer, String> map = new HashMap<>(); 
  
        map.put(1, "Java"); 
        map.put(2, "C"); 
        map.put(3, "PHP"); 
        map.put(4, "Python"); 
  
        System.out.println("Map: " + map); 
  
        Stream<Map.Entry<Integer, String> > stream = map.entrySet().stream(); 
  
        System.out.println("Stream: " + Arrays.toString(stream.toArray())); 
    }
}


/*
run:

Map: {1=Java, 2=C, 3=PHP, 4=Python}
Stream: [1=Java, 2=C, 3=PHP, 4=Python]

*/
