Question

33) What library must be imported to use the Java random number generator class and its methods? Give the correct import statement needed to ensure that this class is available for use in the program using it.

34) Write a valid method in Java that performs a simulated coin-toss – meaning it returns boolean value of either true or false based upon use of the Java random number generator. You may assume the instance of the generator was created elsewhere, and is named coin.

35) Write examples of an integer constant, a floating-point constant and a string constant in Java, where each of these is a static member of the class it is declared

Answer 1

Answer 33: we should use util library
import java.util.*;
Answer 34:
// it will return true or false
// if the generated number is even than it is true else it false
   coin.nextInt()%2==0;
  
Answer 35:
static final int MAX_VALUE=100;
static final double RATE=10.4;
static final String header="RATE";

All these will be declared at class level
