class GroovyTut {
static void main(String[] args) {

    println("Hello World"); 

    //comments can be added using "//" or "/* */" 

    def a = 1;
      // prints the value of "a" and then increments it
    println("a++ = " + (a++));
    
      // increments the value of "b" then prints it
    def b = 1;
    println("++b = " + (++b));

      // prints the value of "c" and then decrements it
    def c = 1;    
    println("c-- = " + (c--));
    
      // decrements the value of "d" then prints it
    def d = 1;
    println("--d = " + (--d));

    }
