What is Java Language?
Java is concurrent,
class-based, object-oriented, and specifically designed to have as few
implementation dependencies as possible. Java technology is used to develop applications
for a variety of environments, from consumer devices to heterogeneous
enterprise systems. This section provides an overview of the Java platform and
its components.
Data types in Java programming are as
below:-
Integer
Integer data types are used only for storing numeric data. That is, a number that has no fractions of its own.
Float
Floating-point types include all types that can have fractions in their numbers, such as 3.14 and pi.
Character
Most modern computer programming languages store alphabets and letters by representing each with a small numeric code.
String
Most modern computer programming languages provide a means of representing strings, which are collections of characters such as words and phrases, to perform manipulation operations on data for various purposes.
Array
An array is a collection of data items all of the same data type. It's easier to do by performing some operations on the index values.
Example:-
public class
Main
{
public static void main(String[] args)
{
int
int_value = 108;
float
float_value = 33.55f;
char
char_value = 'T';
String
str_value = "TCCI";
System.out.println("Integer
value is..."+int_value);
System.out.println("Float
value is..."+float_value);
System.out.println("Character
value is..."+char_value);
System.out.println("String
value is..."+str_value);
}
}
Output:-
Integer value is...108
Float value is...33.55
Character value is...T
String value is...TCCI
TCCI computer classes are located in Bopal
Ahmedabad and ISCON Ambli Road in Ahmedabad.
