System.out.print() vs cout in Java and C++

A question I get asked often in my Java classes is “What is System.out.print() and is it similar to cout in C++?”

First, let’s look at the first half of this question. What is System.out.print()?

System.out.print() is a Java statement that prints the argument passed, into the System.out which is generally stdout (standard output – e.g. the console in simple programs).

  1. System is a Class
  2. out is a Variable
  3. print() is a method, there are several

The answer is to the second half is yes, it is similar to cout in C++. System.out and cout are the objects representing the stdout stream in Java and C++ respectively. System.out.print is a method so it would be more similar to printf (the function in stdio.h in C++).

Similarly, System.in and cin are the objects representing the stdin stream in Java and C++ respectively.
