Java Declaration Statement Definition

Java Declaration Statement Definition One kind of Java statement is a declaration statement, which is  used to declare a variable by specifying its data type and name. Below are some examples of declaration statements. A variable, in relation to Java programming, is a container that holds values used in a Java program.

The two boolean variables isFinished and isAlmostFinished are declared with initial values of false and true respectively. Finally, the String variable welcomeMessage is assigned the String value of Hello!, while the variable farewellMessage is simply declared as a String. There are also control flow statements in Java as well as expression statements.
