Properties get(key) method in Java with Examples Last Updated : 30 Sep, 2019 Comments Improve Suggest changes Like Article Like Report The get(key) method of Properties class is used to get the value mapped to this key, passed as the parameter, in this Properties object. This method will fetch the corresponding value to this key, if present, and return it. If there is no such mapping, then it returns null. Syntax: public Object get(Object key) Parameters: This method accepts a parameter key whose mapping is to be checked in this Properties object. Returns: This method returns the value fetched corresponding to this key, if present. If there is no such mapping, then it returns null. Below programs illustrate the get(key) method: Program 1: Java // Java program to demonstrate // get(key) 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("Properties: " + properties.toString()); // Getting the value of Pen System.out.println("Value of Pen: " + properties.get("Pen")); // Getting the value of Phone System.out.println("Value of Phone: " + properties.get("Phone")); } } Output: Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400} Value of Pen: 10 Value of Phone: null Program 2: Java // Java program to demonstrate // get(key) 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()); // Getting the value of 1 System.out.println("Value of 1: " + properties.get(1)); // Getting the value of 5 System.out.println("Value of 5: " + properties.get(5)); } } Output: Current Properties: {3=1000RS, 2=500RS, 1=100RS} Value of 1: 100RS Value of 5: null References: https://docs.oracle.com/javase/9/docs/api/java/util/Properties.html#get-java.lang.Object- Comment More infoAdvertise with us Next Article Properties get(key) method in Java with Examples K Kirti_Mangal Follow Improve Article Tags : Java Java - util package Java-Functions Java-Properties Practice Tags : Java Similar Reads Properties keys() method in Java with Examples The keys() method of Properties class is used to get the enumeration of the keys in this Properties object.
