    Default IF statement accumulataion not working properly - random numbers

    I am having trouble figuring out how to write program code that will add up the number of doubles rolled, as well as the number of 7's rolled;the program already notifies the user which dice are 7's and which are doubles.

    I know for the accumulation to work, it has to be an IF statement. I placed my IF statement within my MAIN method, but it does not seem to be working properly. For program running purposes only, I /* */ out the IF statement in case you wanted to copy and paste the program to see how it runs without the IF statement.

    I am getting the hang of Java, but it's always tricky and confusing a bit.

     
    import java.util.Random;
    public class DiceGame
    {
    	public static void main(String [] args)
    	{
    		Random newnum = new Random();
     
    		int roll_1 = 0;
    		int roll_2 = 0;
    		int counter;
     
    		boolean Doubles;
    		int Doublecounter;
     
    		System.out.println("Dice #1" + "\t" + "\tDice #2");	
     
     
    		for(counter=1;counter<=10;counter++)
    		{
    			roll_1=1 + newnum.nextInt(6);
    			roll_2=1 + newnum.nextInt(6);
     
     
    			System.out.println(" ");
    			System.out.print(roll_1);
     
    			System.out.print("\t" + "\t" + " ");
    			System.out.print(roll_2);
     
    			Doubles(roll_1, roll_2);
    			Seven(roll_2, roll_1);
     
    		}
     
    		/*
    		int Doublescounter;
    		if(Doublecounter > 1)
    		{
    		System.out.print("Number of doubles include: ");
    		Doublescounter++;
    		}*/
     
     
    	}
     
    	public static boolean Doubles(int roll_1, int roll_2)
    	{
    		if(roll_1==roll_2)
    			{
     
    				System.out.print("     - Doubles were rolled.");
    				return true; 
    			}
    		else
    				return false;
     
    	}
     
    	public static boolean Seven(int roll_1, int roll_2)
    	{
    		if((roll_1 + roll_2)==7)
    			{
    				System.out.print("     - The roll totaled 7.");
     
    				int total1 = 0;
    				return true;
    			}
    		else
    				return false;
     
    	}
     
    }

    Default Re: IF statement accumulataion not working properly - random numbers

    The variable that holds the count MUST be defined and initialized outside of the processing loop.
    If you don't understand my answer, don't ignore it, ask a question.
