No, in Java, only signed numbers are defined.
No..Java Supports Signed positive and negative integers
No. Java uses no unsigned numbers.
Normally, signed and unsigned data types just refer to whether or not a value can be negative or not. An unsigned 4-bit value can be the values 0 to 15 A signed 4-bit value can be the values -8 to 7 However, there is no such thing as an unsigned value in Java*. All primitive types are signed by default and cannot change. *Note that technically a char value can be considered an unsigned type. The only way to see this is to declare a char with value '\uffff' (or 65535) and try to print it out as both a short and an int. If you try this with any other data types, the larger values will display the same as the smaller values. Not so with the char example.
All built-in data types are not abstract data types.
If an object oriented language supports the concept of primitive data types then the language is not a pure. C++ is not pure because it supports raw data pointers and fundamental types like int and float, none of which have member methods associated with them. Java, on the other hand, is pure object oriented because it has no primitive data types; all types are implemented as objects. Java is therefore easier to use than C++, but is less efficient because it provides no low-level interaction with the machine.
define the data types
Java Supports International programming so java supports Unicode
There are two main categories of variables in Java. They are primitive and non primitive. Primitive data types are the basic data types like int, float, char etc. These are not objects. The other non primitive data types are all types of Java Objects. Example: String, ArrayList etc.
That means that Java is fairly strict about data types.
Java is a powerful language that gives us options to have data in different forms. We have several data types that we can use for our needs. The basic data types that java offers us are termed as Primitive Data Types. Though all programming languages have varied data types java offers us with a variety of data types that are much powerful and simplified to use when compared to other languages.The Java programming language is strongly-typed, which means that all variables must first be declared before they can be used. This involves stating the variable's type and name.int age = 10;The above statement tells the java compiler that a field named "age" which holds numeric data and having an initial value of 10 is declared. A variable's data type determines the values it may contain, plus the operations that may be performed on it. In addition to int, the Java programming language supports seven other primitive data types. A primitive type is predefined by the language and is named by a reserved keyword. Primitive values do not share state with other primitive values. The eight primitive data types supported by the Java programming language are:byte, short, int, long, float, double, char and boolean
There are a total of 8 simple or primitive data types in Java. They are:byteshortintfloatdoublebooleanlong andString
