18 sie 2021 · In the print statement, while calling the Sum() and Ave() method, you need to use the class object to call it. Use exam.Sum() and exam.Ave() instead. For any Class, you cannot call a non-static method or access the non-static variables directly.
The Scanner class is used to get user input, and it is found in the java.util package. To use the Scanner class, create an object of the class and use any of the available methods found in the Scanner class documentation.
In this quick tutorial, we’ll illustrate how to use the Java Scanner class – to read input and find and skip patterns with different delimiters. 2. Scan a File. First – let’s see how to read a file using Scanner. In the following example – we read a file containing “ Hello world ” into tokens: @Test public void ...
