Java 8 ObjDoubleConsumer Interface

ObjDoubleConsumer Interface :-

ObjDoubleConsumer ( java.util.function.ObjDoubleConsumer ) is a functional interface that has one abstract method declared in it. This interface is a specialised form of BiConsumer interface.

Abstract method :-  

void  accept ( T t , double value ) :- The abstract method accept ( T t , double value ) is a functional method. It accepts two parameters as an argument ( one generic object and second double value ) and return no value, it performs the operation defined by the ObjDoubleConsumer interface ( usually a lambda expression passed as an argument ). 

Reference :-  ObjDoubleConsumer Interface JavaDocs 

Example :- 

In this example, we will declare a ObjDoubleConsumer interface that prints the value of a parameter passed as a argument.

  public static void main(String[] args){
 
    ObjDoubleConsumer<String> biConsumer = ( x , y ) -> { System.out.println(x + " " +y);};
 
    // Example of accept 
    biConsumer.accept("Interface",2.00); 
  }  

Result :- 

Interface 2.0
