QUESTION 11

1. In util package,

   public class Example {

      public static void showMessage( String s ){        .......    }    
      public static int getInt( String prompt ){        .......  }
   }
   
   Using these method you see above to create a main method in your class called MyExam in the different package to get input and output.
   The output will tell the user what number is entered. If you entered a 5, the output will be: "The number you entered is 5.".

QUESTION 12

1. Create a method using loop and if-else to identify 5 numbers, print out which number is odd and which number is even. You will use the following method to gereratethose 5 numbers:    int randomNum = (int)(Math.random() * 101); // generate number between 0 to 100. The operator you will use is "%", this operator will return the division remainder, for example: 134%5 = 4. The output should be like: "3 is an odd number.", "24 is an even number." The name of the method will be isOdd.

public class MyProgram{
        public static void main(String[] args) {
                for(int i=0;i<5;i++) {
                        int randomNum = (int)(Math.random() * 101);
                        if(randomNum % 2 == 0)
                                System.out.println(randomNum+" is an even number");
                        else
                                System.out.println(randomNum+" is an odd  number");
                }
        }
}
