Help with output

[cdoan17]

Hi,

So I'm trying to figure out why I keep getting this output:

a-b c-d-

when I'm trying to get this output:

a-b c-d

It's driving me crazy. My print command is bounded within the loop function. In the end, x should equal zero before it hits the end of the loop. Please help!

class shuffle1 {
	public static void main (String[] args) {
		int x = 3;
		while (x > 0) {
			if (x > 2) {
				System.out.print ("a");
			}
			
			if (x == 2) {
				System.out.print ("b c");
			}
			
			if (x == 1) {
				System.out.print ("d");
					x = x - 1;
			}
			
			x = x - 1;
			
			System.out.print ("-");
			
		}
		
		System.out.println();
	}
}

Thanks!

Hi,

you will change your code like below.... I think that will be works...

class shuffle1 {
public static void main (String[] args) {
int x = 3;
while (x > 0) {
if (x > 2) {
System.out.print ("a");
}

if (x == 2) {
System.out.print ("b c");
}

if (x == 1) {
System.out.print ("d");
x = x - 1;
}

x = x - 1;
if(x!=0){

System.out.print ("-");
}

}

System.out.println();
}
}

thanks,

I changed it like you posted. I'm still getting the same output:

a-b c-d-

It's strange. That little dash at the back is really annoying.

Hi,

This is definitely works Already i was tested..
So use this....

public class shuffle1 {
public static void main (String[] args) {
int x = 3;
while (x > 0) {
if (x > 2) {
System.out.print ("a");
}

if (x == 2) {
System.out.print ("b c");
}

if (x == 1) {
System.out.print ("d");

}

x = x - 1;
if(x!=0){

System.out.print ("-");
}

}

System.out.println();
}
}
Thanks,

I find it a vey convoluted way of printing such a simple line; the simplest way to print it is:

System.out.println("a-b c-d");

but if you really, really want to use a loop here: three parts are printed: "a-" "b c" and "-d"; why not use it and do:

for (int i=0; i < 3; i++) {
   switch (i) {
      case 0: System.out.print("a-"); break;
      case 1: System.out.print("b c"); break;
      case 2: System.out.println("-d"); break;
   }
}

kind regards,

Jos
