Overview: A.= Can be used for basic types and reference types: when used for basic types, compare whether the values are the same; when used for reference types, compare whether the objects are the same. B.For string a = "A"; integer B = 1; this

2) = and equals in Java, equals in java = And equals in Java  1. If the Compare object is a value variable: only use = 2. If the Compare object is a reference variable: =: compare whether two references point to the same object instance.

The Equals method in the object class is used to detect whether an object is equal to another object. In the object class, this method determines whether two objects have the same reference, and if two objects have the same reference, they must be

Each Java object has a hashcode () and Equals () method. Many classes ignore (Override) default implementations of these methods to provide deeper semantic comparability between object instances. In the Java Philosophy and Practice section, Java

First look at the comparison between the basic value types in the CLR, first look at the code: intAge1 = -; intAge2 = -; Console.WriteLine ("int = = Int: {0}", Age1 = =age2); Console.WriteLine ("int = = Int: {0}", Age2 = =age1);
