How are constants and variables important in devoloping java programs?
Without variables, you won't be able to do much programming. Variables is where you store data; such data may change over time. And computer programming is all about manipulating data.
Attributes and methods of uppercase in java?
In Java toUppercase() is a method of the class String: https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#toUpperCase()
Enum in java?
Enum in java is a keyword which is introduced in JDK 1.5 and its a type like Interface and Class.Enum constants are implicitly static and final and you can not change there value once created. Enum in Java provides type-safety and can be used inside switch statment like int variables. Since enum is a keyword you can not use as variable name and since its only introduced in JDK 1.5 all your previous code which has enum as variable name will not work and needs to be refactored.

What are constants and variables in a lab experiment?
In a lab experiment, constants are the conditions that are kept the same throughout the experiment to ensure that the results are valid and reliable. Variables, on the other hand, are factors that can change; they are typically categorized into independent variables (which are manipulated) and dependent variables (which are measured). Managing constants and variables is crucial for establishing a clear cause-and-effect relationship in the experiment.
How are constant variables different from independent variables?
Constants stays the same independent variables is the variable that is being manipulated
