Explain Booleans in java?

Booleans are named after George Boole, a nineteenth century logician. Every boolean variable has one of two values, true or false. These are not the similar as the Strings "true" and "false". They are not the similar as any numeric value like 1 or 0. They are simply true and false. Booleans are not numbers; they are not Strings. They are simply booleans.

Boolean variables are established just like any other variable.

boolean test1 = true;
boolean test2 = false;

Remember that true and false are reserved words in Java. These are known as the Boolean literals. They are case sensitive. True along with a capital T is not the similar as true with a little t. The similar is true of False and false.
