Java Variables

Variables are containers for storing data values.

In Java, there are different types of variables, for example:

• String – stores text, such as “Hello”. String values are surrounded by double quotes
• int – stores integers (whole numbers), without decimals, such as 123 or -123
• float – stores floating point numbers, with decimals, such as 19.99 or -19.99
• char – stores single characters, such as ‘a’ or ‘B’. Char values are surrounded by single quotes
• boolean – stores values with two states: true or false
  

Declaring (Creating) Variables

To create a variable, you must specify the type and assign it a value:

SyntaxGet your own Java Server

type variableName = value;

Where type is one of Java’s types (such as int or String), and variableName is the name of the variable (such as x or name). The equal sign is used to assign values to the variable.

To create a variable that should store text, look at the following example:

String name = "John";
System.out.println(name);
