Variables and operators in Groovy

Variables and operators are the basic building blocks of any programming language, and Groovy is no exception. Here is an overview of variables and operators in Groovy:

1. Variables: Variables in Groovy are declared using the def keyword, followed by the variable name. For example:

   python
   Copy code
   def name = "John Doe"
   Copy
   

   Groovy is a dynamically typed language, so the type of a variable is determined at runtime, not compile-time. This means that you don't need to specify the type of a variable when you declare it, and the type can change dynamically as the program runs.

2. Operators: Groovy supports the standard set of arithmetic, comparison, and logical operators. Here are some examples:

   • Arithmetic operators:

     java
     Copy code
     def x = 42
     def y = 10
     
     def sum = x + y    // 52
     def diff = x - y   // 32
     def prod = x * y   // 420
     def quot = x / y   // 4.2
     def mod = x % y   // 2
     Copy
     

   • Comparison operators:

     java
     Copy code
     def x = 42
     def y = 10
     
     def isEqual = x == y    // false
     def isNotEqual = x != y   // true
     def isGreater = x > y   // true
     def isLess = x < y   // false
     def isGreaterEqual = x >= y   // true
     def isLessEqual = x <= y   // false
     Copy
     

   • Logical operators:

     java
     Copy code
     def x = true
     def y = false
     
     def and = x && y   // false
     def or = x || y   // true
     def not = !x   // false
     Copy
     

These are the basic operators that are used in Groovy. Groovy also supports other types of operators such as ternary operators, bitwise operators, and more. The syntax for these operators is similar to other programming languages, making it easy to learn for developers with prior programming experience.
