Answer:
The code to this question can be given as:
Code:
public interface Test
{
public abstract Duration getDuration();
public abstract Result check(int ar);
public abstract double getScore();
}
Explanation:
An interface is similar to Java Class, and it has only static variables and abstract methods. Java uses a multi-inheritance interface. Many Java interfaces can be implemented by a Java class. All methodologies were implicitly public and abstract within an interface.
In the given question we a function that is "Test" and inside the interface, we define three functions that are defined as:
- First, we declare a "getDuration" method that returns the Duration object.
- Second, we declare a "check" method that accepts an integer variable that is "a".
- Third, we declare a "getScore" method that returns a double value.

Three visual data analysis tools. are :
-
Charts
- Dashboards
- Graphs
Explanation:
- Visual Analytics is the science of analytical reasoning supported by interactive visual interfaces. Today, data is produced at an incredible rate and the ability to collect and store the data is increasing at a faster rate than the ability to analyze it.
- Tableau is a great option for those who need to create maps in addition to other types of charts. Tableau Public is also a great option for anyone who wants to create public-facing visualizations
- Dashboards are where the majority of data visualization takes place. They create charts and graphs for specific data, constantly updating with the latest real-time information to keep you informed. Dashboards are great for at-a-glance or ad-hoc analysis when you just need to quickly check your data.
- Data visualization is another form of visual art that grabs our interest and keeps our eyes on the message. When we see a chart, we quickly see trends and outliers.
