Strong static typing helps detect errors at compile time. Variables in dynamically typed languages like Ruby or Python can receive different data types over the time. In Java, once a variable is declared to be of a certain data type, it cannot hold values of other data types. There are two...

A non-primitive or reference data type holds the reference to an object in memory. Using the reference stored in the variable, you can access the fields and methods of the referenced object. For example,java.lang.Stringis a class defined in the Java library and you can use it to manipulat...
As explained in the previous chapter, a variable in Java must be a specified data type:ExampleGet your own Java Server int myNum = 5; // Integer (whole number) float myFloatNum = 5.99f; // Floating point number char myLetter = 'D'; // Character boolean myBool = true; // Boolean...
2) Non-Primitive (Reference) Data Type: A reference data type is used to refer to an object. A reference variable is declare to be of specific and that type can never be change. We will talk a lot more about reference data type later in Classes and Object lesson....
What is the character data type in Java? How do I declare and initialize a char variable in Java? Can I store more than one character in a char variable? What is the Unicode representation of a char in Java? How can I convert a char to an integer in Java?

Each of the geometry engine methods are static, which means they can be called directly on the class (without instantiating an object variable). Project geometries to a new spatial reference There may be times when you have geometries in a map or service with a particular spatial reference and...

ColdFusion built-in complex data types include arrays, structures, queries, and XML document objects. You cannot use a complex variable, such as an array, directly in a ColdFusion expression, but you can use simple data type elements of a complex variable in an expression. For example, with...
