        Above is a screenshot of  the basic arithmetic functions executed in Groovy. The arithmetic symbols used in Java is very similar to Groovy. A new symbol used in Groovy that is not used in Java is the dollar sign symbol. This is used in print statements. In java, when a person is coding a print line and they are concatenating words with a variable, quotations and a plus symbol is used. However, in Groovy, the whole print statement is inside quotation marks and a dollar sign is used to separate the variable with the words. This can be seen below.



The types of variables in Groovy are ints, floats, long, short, bytes, char, booleans, strings and doubles. These are similar to Java. When creating a variable in Groovy, the word def is used in front of the new variable. For example, def a = 2. However, if a person is checking to see if a is equal to 2, they would write the line, assert a==2. Lists can be made in Groovy, simply by writing, def list = [0,1,2,3,4] or any desired values inside the given list.

    Does a variable that is being concatenated with a string need to be surrounded by curly brackets {} like shown in the first screenshot?

    Can Groovy variables be only declared and not initialized with some value in one line of code? If so, how does Groovy know what type of variable is being declared without being initialized with some value?

Description of interesting language facet # 2

Description of interesting language facet #2         In Groovy, objects are used for almost everything. Due to the fact that Groovy uses objects, Groovy automatically will wrap the types of variables in the code. Something that is worth mentioning is boxing and unboxing. When the coder is converting a primitive data type to an object it is called unboxing. Likewise, when the coder is converting an object to a primitive data type. For clarification purposes, there are eight primitive types which are  boolean , byte , char , short , int , long , float and double. In Java, widening is done before boxing is done. Widening is defined as taking a small primitive type value and is automatically accommodated in a bigger primitive data type.  The first method is the method that Java prioritizes because it does widening rather than boxing. However, for Groovy, the second method would be the method that would be called because no matter what c...

Implementation of binary search in the language

Implementation of binary search in the language                         Searing through data can be a very tedious task for the coder, so binary search was invented to search through data in an efficient manner. A key detail is that for the coder to use binary search to search through a set of data, that given data must already have been sorted in order for it to work.                         Binary search allows the coder to search through a sorted array or list of data in an efficient manner. In groovy, binary search is implemented by allowing the coder to divide the data in half and then check for the desired value. Then if the value is not in that given data set, the other half of the data set is checked. The data set is then divided into a new interval for the code This cycle is then repeated until the value is determined or the interva...

Methods, procedures or encapsulation

Methods, procedures or encapsulation When creating a method, the word def is used in front of the method or the method gives a return type to clarify that is a method. There are three modifiers that can be used for a method: public, private, or protected.  The default modifier in Groovy is public, so if no modifier is given, then it will automatically be public. Parameters for methods in Groovy are handled the same way as they are in Java, the parameter names mus differ from each other. In Groovy, if no parameters are given inside the method, Groovy has default parameters that are passed in.  An example is def method(parameterA = 0, parameterB =0, parameterC=0) { } A main method in Groovy is as seen below. static void main(String[] args) { }  Groovy also has instance methods. These methods can be accessed by instantiating an object to call upon the object. There are optional modifiers that can be used on methods. These include static, final, or s...
