What is boolean?

boolean is a basic data type in Java that represents a Boolean value, either true or false.

Features:

• can only take two values: true or false
• Usually used in conditional judgments and loop statements

Usage:

The syntax for declaring Boolean variables is:

For example:

boolean isTrue = true; boolean isFalse = false;

Comparison operators:

The boolean data type supports the following comparison operators:

• == (equals)
• ! = (not equal to)

• && (With)
• || (or)
• ! (Negative)

Notes:

• Boolean values cannot be automatically converted to other data types and vice versa.
• You can use theBoolean.valueOf(string)method to convert a string into a Boolean value.
• You can use theBoolean.toString(boolean)method to convert a Boolean value to a string.
