The containsValue(value) method of Properties class is used to check if this Properties object contains any mapping of this Value. It takes this value to be compared as parameter and returns a boolean value as result.
Syntax:
public Object containsValue(Object value)
Parameters: This method accepts a parameter value which is the value to be searched in this Properties.
Returns: This method returns a boolean value stating the result whether this value is present in this Properties object or not.
Below programs illustrate the containsValue(value) method:
Program 1:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
Properties properties = new Properties();
properties.put( "Pen" , 10 );
properties.put( "Book" , 500 );
properties.put( "Clothes" , 400 );
properties.put( "Mobile" , 5000 );
System.out.println( "Current Properties: "
+ properties.toString());
System.out.println( "Is 10 present: "
+ properties.containsValue( 10 ));
}
}
|
Output:
Current Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400}
Is 10 present: true
Program 2:
import java.util.*;
public class GFG {
public static void main(String[] args)
{
Properties properties = new Properties();
properties.put( 1 , "100RS" );
properties.put( 2 , "500RS" );
properties.put( 3 , "1000RS" );
System.out.println( "Current Properties: "
+ properties.toString());
System.out.println( "Is 200RS present: "
+ properties.containsValue( "200RS" ));
}
}
|
Output:
Current Properties: {3=1000RS, 2=500RS, 1=100RS}
Is 200RS present: false
