Java Program to convert Properties list into a Map
To convert Properties list into a map, let us first create an object of Properties class −
=Properties p = new Properties();
Now, use setProperty() to set key-value pair −
p.setProperty("P", "1");
p.setProperty("Q", "2");
p.setProperty("R", "3");
p.setProperty("S", "4");
p.setProperty("T", "5");
p.setProperty("U", "6");With that, the following is how the Properties list is converted into a Map −
HashMap<String, String>map = new HashMap<String, String>((Map) p);
Example
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
public class Demo {
public static void main(String args[]) {
Properties p = new Properties();
p.setProperty("P", "1");
p.setProperty("Q", "2");
p.setProperty("R", "3");
p.setProperty("S", "4");
p.setProperty("T", "5");
p.setProperty("U", "6");
p.setProperty("V", "7");
HashMap<String, String>map = new HashMap<String, String>((Map) p);
Set<Map.Entry<String, String>>set = map.entrySet();
System.out.println("Key and Value of the Map... ");
for (Map.Entry<String, String>m: set) {
System.out.print(m.getKey() + ": ");
System.out.println(m.getValue());
}
}
}Output
Key and Value of the Map... P: 1 Q: 2 R: 3 S: 4 T: 5 U: 6 V: 7
