difference between = = and JavaScala's = = follows the comparison rules:First check whether the left side is null, if not, call the left manipulation data of the Equals method. Therefore, the exact comparison depends on the definition of the Equals method that makes the operation. Because of the automatic null check, there is no need to manually check it again.java = = can compare primitive types or reference types. For primitive types, the equality of the = = Comparison values for

Geotools is a Java class library that provides many standard classes and methods to process spatial data. At the same time, this class library is built on the OGC standard and is an implementation of the OGC idea. OGC is an international standard, so geotools will surely become the main tool for open-source space data processing in the future. Most open-source so
