Answer:
Java Variable :
A Java variable is a piece of memory that can contain a data value. A variable thus has a data type. Data types are covered in more detail in the text on Java data types. Variables are typically used to store information which your Java program needs to do its job.
Data types :
- String (or str or text).
- Character (or char).
- Integer (or int).
- Float (or Real).
- Boolean (or bool).
String :
In Java, string is basically an object that represents sequence of char values.
