Java local variable

You can set the value of the field by calling the set() method on the Field object , where the first parameter is the object that has the field value that you’d like to set, and the second parameter is the value of that field. There are other ‘set’ methods for primitive (non-object) field types.

To declare (create) a variable, you will specify the type, leave at least one space, then the name for the variable and end the line with a semicolon ( ; ) . Java uses the keyword int for integer, double for a floating point number (a double precision number), and boolean for a Boolean value (true or false).
