smallest individual unit in a program.

C - Constants and Literals. Constants refer to fixed values that the program may not alter during its execution. These fixed values are also called literals. Constants can be of any of the basic data types like an integer constant, a floating constant, a character constant, or a string literal.

shameemsingh — 2020-07-10 18:11:34 UTC

Example : character constant - 'a'
or '@' or '5'
integer constant - 56, 897
String literal - "jayesh"
Floating literal - 3.24 f, 4.0d

List of in built word commands already known to JAVA compiler. Cannot be used as identifiers.

Name given by the programmer to different parts of a program.

It cannot contain spaces, period
(.) or any other special symbol except for _ and $ and they cannot be keywords.

Symbols used to differentiate between different parts of a program.

It is an integrated development environment of JAVA where a program is created, compiled, executed and checked for errors.

Datatype is a keyword that defines the type of data that is being stored in a variable.

shameemsingh — 2020-07-13 10:51:51 UTC

Example : int , byte or long (for numbers without decimals)
float or double(numbers with decimals)
char( single characters written within single quotes - 'A', '#', '9'

Variable is a named memory location that stores a value that can change during the execution of a program.

shameemsingh — 2020-07-13 10:57:46 UTC

Example : sum, name, age, salary, gender, x,y,z etc
Declaration means defining the name and datatype of a variable before its use in a program.
Example : int sum;
float average;
char gender;

It means storing a value in a variable at the time of declaring it or before its use in a program. Example int age=25; char grade='A' double pie=3.14;

int a,b,c;
float x,y;
We can even initialize them together
int a=3,b=4;
float x=2,y=4,z=0;
Use comma instead of semicolons between the variables while initializing multiple variables in the same line.

Simple BlueJ has a deliberately smaller and simpler interface than professional environments like NetBeans or Eclipse. ...
Designed for teaching BlueJ is deliberately designed with good pedagogy in mind.

BlueJ is an integrated development environment (IDE) for the Java programming language, developed mainly for educational purposes, but also suitable for small-scale software development.

Java keywords are also known as reserved words. Keywords are particular words which acts as a key to a code. These are predefined words by Java so it cannot be used as a variable or object name.
