HELP! with Java Programming

[tenzuu]

I cannot seem to figure out methods, i have to write this program but i am lost in the methods. Here is the question on the program.

/*Create a simple Java program to generate a random number that is smaller than 100 and divide the number by 2.
If the number is an odd number, display a message that this number is an odd number.
Otherwise, display this number is an even number. Use the above different types of method to develop this program.

public void displayResult(String)
public boolean isEvenNumber(int)
public int getNextNumber()
public void execute()
public static void main()
*/
This is what i have so far............
************************************************** *************************
import java.util.*;

public class Assignment6{

public static void main(String args[]){

Assignment6 myAssignment6 = new Assignment6();
Assignment6.execute();
}

public void execute(){
Random randomNumbers = new Random(100);
int generateNum = randomNumbers.nextInt();

System.out.println("\n\n\nThe number generated is "
+ generateNum);

if (generateNum % 2 == 0){
System.out.println("The number generated is an even number");
}
else{
System.out.println("The number generated is an odd number");
}
}
