These are really 2 questions, so I have given the answers in 2 sections below.
Parentheses (): These are used to group expressions together, define function parameters, and call functions.
Angle brackets <>: In Java, angle brackets are used for generics.
It’s important to note that these are standard uses of these brackets, and the specific context of the code will determine the actual use of the different types of brackets.
What is the purpose or role of each type?
Parentheses (): They are used to group expressions together, define function parameters, and call functions. For example, in the statement “System.out.println(“Hello World!”);”, the parentheses are used to call the “println” method of the “out” object of the “System” class.
Angle brackets <>: In Java, angle brackets are used for generics. Generics allow you to write a class or method that can work with multiple types. For example, in the statement “List<String> myList = new ArrayList<String>();” angle brackets are used to specify that the list should only contain strings.
