How to define a boolean variable in Java?

In Java, you can define boolean variables using the keyword “boolean”. Boolean variables can only have two values: true and false. Below is an example code for defining a boolean variable:

boolean isTrue = true;
boolean isFalse = false;

In this case, the variable isTrue is assigned the value true, while the variable isFalse is assigned the value false. Boolean variables can be assigned different values as needed.
