As you run code the output will be:


You can see, a variable a is declared without a value while variable ‘b‘ is assigned a value at the time of declaration. You may define a java float variable by using the keyword: float followed by the variable name.

To assign a value to a float variable, you can use different ways. At the time of declaration use float in brackets followed by the value. Similarly, if you have not assigned a value at the time of declaration, you can assign it later, during the program. Finally, the value of variable ‘a’ is printed by using the java statement.
