Operations associated with such data types are those of simple. Operators: given the integer encoding, arithmetic operators. After the numbers are manipulated, the result must be converted from the int format to char format for display on the screen. These primitive data types hold only numeric data. The type of operations that can be performed with the data.

The text string must be converted to int format. If a user entered “\(123\)” from the keyboard, the operating system would read the individual characters, each in char format, and store them as a text string. The int format is easier to use in arithmetic and logical expressions, but the interface with the outside world through the screen and the keyboard uses the char format. (Recall that a C-style string is terminated with a NUL character.)

Logical operators are use to determine the logic between variables or values. ("x is less than or equal to y: " + (x <= y)) ("New value of y and z: " + y + " and " + z) Ĭomparison operators are use to compare two values. ("Value of y and z: " + y + " and " + z) ("New value of x as division reminder: " + x) This will use new value of x which is 16 to perform the operation This will use new value of x which is 80 to perform the operation ("New value of x after multiplication: " + x) This will use new value of x which is 40 to perform the operation They determine what operations can be performed on the data, like addition, subtraction, and multiplication.

They tell the computer how to interpret the bits of data either as a character, a number, a date, or something else.

("New value of x after substraction: " + x) A data type is an attribute of data that tells the computer what a group of binary data represents. This will use new value of x which is 50 to perform the operation ("Decrement of y: " + y) Īssignment operators are use to assign values to variables. ("Division of 1 number by another: " + z) Īrithmetic operators are used to perform common mathematical operations, such as:-īelow is an example which show how these operators can be used. Java divides the operators into the following groups: Information can be of any data type such as int, string, boolean or float. Variable is a reserved space or a memory location to store some sort of information. Variables are containers for storing data values. Stores fractional numbers from 1.7e−308 to 1.7e+038. Sufficient for storing 6 to 7 decimal digits Stores fractional numbers from 3.4e−038 to 3.4e+038. Stores whole numbers from -32,768 to 32,767

Non-primitive data types – such as String, Arrays and Classes.

Datetime and Interval Data Types which include the datetime data types of DATETIME, TIMESTAMP, TIMESTAMPTZ, and TIMESTAMP-LTZ and the interval data types of DSINTERVAL and YMINTERVAL.

Primitive data types – includes byte, short, int, long, float, double, boolean and char Numeric Data Types which are INTEGER, SHORTINTEGER, LONGINTEGER, DECIMAL, SHORTDECIMAL, and NUMBER Text Data Types which are TEXT, NTEXT and ID.

The basic step towards understanding any programming language is to know the data type.Ī Data Type means what type of data the variable can represent.

Java follows the concept of “write once and run anywhere (WORA) which means that compiled java code can be run on all different platforms that support java without the need of recompilation. Java is a general-purpose programming language, which is concurrent class based and object oriented language. I will explain the basics of Java to get you started with Selenium. Java is most commonly used language used with Selenium.
