• Data

The type of data inside our variable.

• Data

• Variables

• Identifiers

• Data Type

It is the name of the variables that the programmer indicated and it is used to read and write to the variable.

• Identifiers

• Datatype

• Variables

• Concatenation

The process of joining strings together with the plus operator.

• Identifiers

• Concatenation

• Datatypes

• Variables

Syntax in declaring variables

• identifier datatype;

  identifier datatype = value;

• datatype identifier

  value = identifier datatype;

• datatype identifier

  value identifier = datatype;

• datatype identifier;

  datatype identifier = value;

Syntax in reassigning variables

• identifier = value

• identifier = value;

• value = identifier

• value = identifier;

Which of the ff. is an example of Concatenation

• "Hello" + "World"

• 2 + 3

• 'a' + 3

• Hello + World

We can display a variable's value by indicating its identifier inside the parenthesis.

• System.outprintIn();

• System.out.printIn;

• System.out.printIn()

• System.out.printIn();

You can use numbers but with letters.

• Rule of Identifier

• Rule of Concatenation

• Rule of Declaring Variables

• Rule of Reassigning Datatypes
