String may also denote more general arrays or other sequence (or list) data types and structures..
What are the 5 data types?
Common data types include:Integer.Floating-point number.Character.String.Boolean.
How many data types are there?
Data types are divided into two groups: Primitive data types – includes byte , short , int , long , float , double , boolean and char. Non-primitive data types – such as String, Arrays and Classes (you will learn more about these in a later chapter)
What is string variable?
String variables, simply speaking, are variables that contain not just numbers, but also other characters (possibly mixed with numbers). But actually a string variable may contain characters such as “\” or “-” or “:” and so on — anything a keyboard may produce. …
What is a string of words called?
sentence – a string of words satisfying the grammatical rules of a language; “he always spoke in grammatical sentences”
What is string and its function?
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). … The most basic example of a string function is the length(string) function. This function returns the length of a string literal.
What is string example?
A string is a data type used in programming, such as an integer and floating point unit, but is used to represent text rather than numbers. … For example, the word “hamburger” and the phrase “I ate 3 hamburgers” are both strings. Even “12345” could be considered a string, if specified correctly.
Why is it called a string?

These four data measurement scales (nominal, ordinal, interval, and ratio) are best understood with example, as you’ll see below.
What is the data type of 1?
1 is an integer, 1.0 is a floating-point number. Complex numbers are written in the form, x + yj , where x is the real part and y is the imaginary part. Here are some examples. Notice that the float variable b got truncated.
What is String  Java?
Strings, which are widely used in Java programming, are a sequence of characters. In Java programming language, strings are treated as objects. The Java platform provides the String class to create and manipulate strings.
How large is a string?
So a string size is 18 + (2 * number of characters) bytes. (In reality, another 2 bytes is sometimes used for packing to ensure 32-bit alignment, but I’ll ignore that). 2 bytes is needed for each character, since . NET strings are UTF-16.
