Constant refers to the value of the variable being constant across the application. So when one object references the variable, it has the same value when references within other objects. Java doesn't have constant's exactly like C sharp or anything.. declaring a variable with "public static" is effectively the same thing.

String variable refers to the data type of the variable. Meaning the variable value will be of the type String.

Does this answer your question?

What do you mean by value? Can you give an example please.

public String foo = "bar"

String is the data type, foo is the variable name, "bar" is the value

The "value" is what's stored in the variable
