Java – predicate method equals()

I'm using the interface predict < T > from com google. common. base(Google Guava)

But I don't know how to make the equals () method effective

Why do I make an error when I enter the following?

Predicate<Object> PredicateD = new Predicate<Object>(){
          @Override public boolean apply(Object number) {
                return ((number instanceof Double) && (Math.floor((Double)number) == (Double)number));
            }    
    };

    Predicate<Object> PredicateM = new Predicate<Object>(){
          @Override public boolean apply(Object number) {
                return ((number instanceof Double) && (Math.floor((Double)number) == (Double)number));
            }    
    };

    System.out.println(PredicateD.equals(PredicateM));

Thank you for your help,

Solution

You are creating two different anonymous inner classes, but neither of them will override equals, so you will get the default implementation, so any two unequal references are treated as unequal

Equals returns false because the values of predicted and predicted are different references
