What are some common data types in programming? Common data types include integers (int), floating-point numbers (float), characters (char), booleans (bool), and strings (str). How do data types affect memory u
1) Primitive data types In Java, we have eight primitive data types: boolean, char, byte, short, int, long, float and double. Java developers included these data types to maintain the portability of java as the size of these primitive data types do not change from one operating system to...
There are three non-primitive data types: strings, arrays and classes, and they all refer to objects. For this reason, they are also known asreference types. Arrays and classes are created by users; strings are predefined in the language. Unlike primitive data types, programmers can use non-...

1. Byte:A byte, for those of you who skipped CS 101, is one of the most basic units of memory made up of 8 individual bits. Byte data types in Java have the following characteristics: Minimum Value:-128 (2^7) Maximum Value:127 (2^7-1) ...
When Java was developed it was anticipated that any Unicode Character would require 16 bits or 2 bytes of memory for storage, these Unicode are used to represent special symbols. Hence, char has size 2 bytes in Java. Now, Let’s see some practical examples of Primitive data types: Adding ...
2.2. Non-primitive Data Types 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 an...
Strings can be any length, limited by the amount of available memory on the ColdFusion server. However, the default size limit for long text retrieval (CLOB) is 64K. The ColdFusion Administrator lets you increase the limit for database string transfers, but doing so can reduce server perform...

Java supports eight basic primitive data types. This tutorial explains basic primitive data types (int, long, short, byte, char, boolean, float, double) with their size, range and default value. Java basic data types are predefined and implicit to the la
