There are many ways to compareHashMaps in Java. We can compare them using theequals()method. The default implementation compares each value. If we change the inner Map’s contents, the equality check fails. If the inner objects are all new instances every time in the case of user-defined...

HashMaphas two important properties:sizeandload factor. I went through theJavadocumentation and it says0.75fis the initial load factor. But I can't find the actual use of it. Can someone describe what are the different scenarios where we need to set load factor and what are some sample ide...
To understand how theWeakHashMapworks,we need to look at aWeakReferenceclass– which is the basic construct for keys in theWeakHashMapimplementation. In Java, we have three main types of references, which we’ll explain in the following sections. ...
