Question

Write a class named acc2 containing: an instance variable named sum of type integer initialized to 0

Answer 1

The TupleClassObject's value can be obtained from the index passed as a parameter by calling the getValue() method in the org. javatuples library.

What is JavaTuples getValue() method?

• The value of the TupleClassObject is retrieved from the index supplied as a parameter using the getValue() function in the org.javatuples package.
• Any tuple class object from the javatuples library can be used using this function.
• It returns an Object value that is the TupleClassObject element present at the index that was supplied as an argument.
• Use of getValue() forfeits type safety because the returned Value is of the Object type.
• Create the class Acc2 and include the instance variable sum of type integer with an initial value of 0.

• A getSum method that returns the sum's value.

public class Acc2 {

private int sum=0;

public int getSum() {

return sum;

}

}
