DecimalFormat form1= new DecimalFormat ("0.####"); // create an instance of . //DecimalFormat
System.out.println (form1.format(res)); // display the value in proper format
Explanation:
Following are the description of the program

- Finally, we print the format by using the format method.In the format method, we pass the variable "res".The System.out.println() is used to display the value of the format.
Answer:
The code to this question can be given as:
Code:
public interface Test //define interface
{
public abstract Duration getDuration(); //define method
getDuration.
public abstract Result check(int a);
//define method
check .
public abstract double getScore();
//define method getScore.
}
Explanation:
In the above code, we define an interface that is "Test" inside an interface, we define three methods that can be defined as:
- First, we define a method that is "getDuration" that method returns Duration as an object.
- Second, we define a method that is "check" this method accepts an integer parameter that is a and return Result.
- The third method is "getScore" this method will return a double value.
