Properties entrySet() method in Java with Examples
The entrySet() method of Properties class is used to get the Set view of this Properties mappings.
Syntax:
public Set<Map.Entry> entrySet()
Parameters: This method do not accepts any parameters.
Returns: This method returns a Set view of the mappings of this Properties object.
Below programs illustrate the entrySet() method:
Program 1:
// Java program to demonstrate// entrySet() method. import java.util.*; public class GFG { // Main method public static void main(String[] args) { // Create a properties and add some values Properties properties = new Properties(); properties.put("Pen", 10); properties.put("Book", 500); properties.put("Clothes", 400); properties.put("Mobile", 5000); // Print Properties details System.out.println("Current Properties: " + properties.toString()); // Using entrySet() to get the set view System.out.println("The set is: " + properties.entrySet()); }} |
Output:
Current Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400}
The set is: [Book=500, Mobile=5000, Pen=10, Clothes=400]
Program 2:
// Java program to demonstrate// entrySet() method. import java.util.*; public class GFG { // Main method public static void main(String[] args) { // Create a properties and add some values Properties properties = new Properties(); properties.put(1, "100RS"); properties.put(2, "500RS"); properties.put(3, "1000RS"); // print Properties details System.out.println("Current Properties: " + properties.toString()); // Using entrySet() to get the set view System.out.println("The set is: " + properties.entrySet()); }} |
Output:
Current Properties: {3=1000RS, 2=500RS, 1=100RS}
The set is: [3=1000RS, 2=500RS, 1=100RS]
