Question

I have a fairly simple question regarding Java. I am currently learning Java and one of the homework questions has me stumped. The goal is to create a triangle with the little figure. I believe I have the idea down however, I cannot get the whole figure of the guy to move to the right.

The code I have so far is:

public class LittleGuy {
    public static final int NUMBER_OF_GUYS = 5; // determines the number of guys.
        public static void main(String[] args) {
            for (int line = 1; line <= NUMBER_OF_GUYS; line++){
                for (int j = 1; j <= (-5 * line + 25); j++){// uses the algorithm.
                    System.out.print(" ");
       }
        guy();

    }
}
public static void guy(){
    System.out.print("  o  ******\n /|\\ *\n / \\ *");
    System.out.println();
    }
}

Basically, the body and the head aren't supposed to be separated. I'm having trouble keeping them together. I am assuming that it is a fairly simple fix I am either unaware of or completely over looking. Any information or thought would be greatly appreciated. Thanks again.

Answer 1

You are only printing out the spaces before the first line of your little guy, inside the guy() method, you are still printing the rest of the guy on the first line.

I'd suggest making a printSpaces(int numSpaces) method which prints numSpaces spaces, and changing the guy method to take the number of spaces to print at the beginning of each line.

Answer 2

public class LittleGuy {

public static final int NUMBER_OF_GUYS = 5; // determines the number of guys.
    public static void main(String[] args) {

        for (int line = 1; line <= NUMBER_OF_GUYS; line++){
            int counter=0;
            for (int j = 1; j <= (-5 * line + 25); j++){// uses the algorithm.
               System.out.print(" ");
               counter++;
   }
    guy(counter);

}
}
public static void guy(int count){

System.out.print("  o  ******");
System.out.print("\n");

for(int i=0;i<count;i++)
System.out.print(" ");    

System.out.print("/|\\ *");
System.out.print("\n");

for(int i=0;i<count;i++)
System.out.print(" ");

System.out.print("/ \\ *");

System.out.println();
}

}

The problem was : In the guy() method you use \\n to print the guy. But it will not take care of the white-spaces you printed in-order to achieve your algorithm (inside the for loop).

How it was solved : place a counter in the for loop to count how many white-spaces were printed and use that counter in the guy() method to print required white-spaces.
