How many numeric data types are there?
How many numeric data types are there?
There are two categories of numeric data types: exact and approximate. Exact data types include integer data types and decimal data types.
How many data types does Java handle real number data?
Real numbers in Java are represented with the float and double data types. As shown in Table 2-3, float is a 32-bit, single-precision floating-point value, and double is a 64-bit, double-precision floating-point value.
What are the 5 data types in Java?
Data types in Java
- Primitive Data Type: such as boolean, char, int, short, byte, long, float, and double.
- Non-Primitive Data Type or Object Data type: such as String, Array, etc.
What are the numeric types?
The exact numeric types are INTEGER , BIGINT , DECIMAL , NUMERIC , NUMBER , and MONEY . Approximate numeric types, values where the precision needs to be preserved and the scale can be floating. The approximate numeric types are DOUBLE PRECISION , FLOAT , and REAL .
Which is not numeric data types in Java?
Java offers two additional non-numeric primitive data types: char (to represent alphanumeric characters and special symbols) and boolean (to represent the truth values true and false).
What are the two types of numerical data?
Numerical data can take 2 different forms, namely; discrete data, which represents countable items and continuous data, which represents data measurement. The continuous type of numerical data is further sub-divided into interval and ratio data, which is known to be used for measuring items.
What is the largest numerical type in Java?
long
The largest integer number that a long type can represent is 9223372036854775807. If we deal with even larger numbers, we have to use the java….Integers.
| Type | Size | Range |
|---|---|---|
| long | 64 bits | -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |
What are the types of data types in Java?
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 are the four types of Java?
There are four platforms of the Java programming language:
- Java Platform, Standard Edition (Java SE)
- Java Platform, Enterprise Edition (Java EE)
- Java Platform, Micro Edition (Java ME)

Which is not numeric data type?
These are data that can’t be manipulated by arithmetic operators. They comprise of Text, String, Date, etc.
What are the four non numeric built in types in Java?
These are int, long, short, byte, float, and double, and they allow us to represent integer and real numbers. Java offers two additional non-numeric primitive data types: char (to represent alphanumeric characters and special symbols) and boolean (to represent the truth values true and false).
