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...

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....
A primitive data type specifies the type of a variable and the kind of values it can hold. There are eight primitive data types in Java: Data TypeDescription byteStores whole numbers from -128 to 127 shortStores whole numbers from -32,768 to 32,767 ...
and every expression has a type that is known at compile time. Java language is also a strongly typed language because types limit the values that a variable can hold or that an expression can produce, limit the operations supported on those values, and determine the meaning of the operations...
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...
