Above is the code and output for the Hello World program. This program is executed very similarly in java. The print command is the one that is used in Java. One difference between Groovy and Java is the lack of parentheses. In Java, this line of code would have been println("Hello World!"). However, in Groovy it is simply println "Hello World. For this line of code,  a semi colon was not necessary. Semi colons are not used in Groovy to end a line of code.

 The overall syntax for this program was similar to Java with a few exceptions. To define and assign a variable, the word def is used. An example would be: def name. Groovy also has assert statements which are similar to if statements  and booleans in Java. The assert statements are executed if the statement is true. If the statement is not true, then the code is not executed.

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...
