Why is there a need to override hashcode if I override the 'equals' method in Java?

I wish did fix the issue.
I don't understand what the two PhoneNumber instance he talks about.
m.put(new PhoneNumber(707, 867, 5309), "Jenny"));
m.get(new PhoneNumber(707, 867, 5309)); // Notice the use of "new"
PhoneNumber phoneNum = new PhoneNumber(707, 867, 5309);
m.put(phoneNum, "Jenny"));
m.get(phoneNum); // Not NULL

Why does Java's Area#equals method not override Object#equals?

like below fixes the issue RealSkeptic linked to JDK-4391558 in a comment above. The comment in that bug explains the reasoning:

@Override public boolean equals(Object o) "Method does not override and superclass method"

This might help you My project had a class within the same package as the class exhibiting the compilations issue... this obscured the Java's base Object class (and its equals() method).
Here's the corrected code:
@Override
public boolean equals(java.lang.Object obj)
{
    return true;
}

can not invoke Equals method on the primitives->Override Equals method not working -beginner 's mistake in Java

wish helps you I obtained compiling errors when overriding the Equals method more specifically at Float and Double parentheses, weight and price attributes, the HashCode method seems to work, so I don't know where the problem is in my code. The code also contains an interface Vehicle, but I don't expect the error to be from the interface. I am not sure if I understood entirely the Equals method . Can someone help me? , Simple syntax errors.
equals(Float)other.weight)
equals((Float) other.weight)
if((Double)(this.price))
if(((Double)(this.price))

Why doesn't this equals method properly override the object.equals method?
