Thread: 'ELSE' missing 'IF'

Hi there,

This is my first post in the forums. Honestly I need your help.
I'm a beginner at programming java. Currently studying systems engineering of course.
I'll be happy to help you out when I become a little more knowledgable.

Problem:
I am having this issue displayed in the cmd:

Asterisco.java:42: error: 'else' without 'if'
else if ( c <= 1 )
^
Asterisco.java:64: error: while expected
}
^
Asterisco.java:68: error: reached end of file while parsing
3 errors

Brief Overview of Program:

The program prints a given number of * within a line, and then continues printing this line a given number of times.
The number of * printed together in a line are the colums or columnas in spanish.
The number of lines of * printed are the rows or lineas in spanish.

An example should look like this in the cmd;

Columns (Columnas): 4
Rows (Lineas): 7

Code of program:

import java.util.Scanner;
public class Asterisco{
    public static void main(String[] args ){
 
    Scanner sc = new Scanner(System.in);
    int c;
    int l;
    char r;
    int contern;
 
    String Aster = "*";
    contern = 2;
 
 
        do{
//Openning message
 	        System.out.println( " \n\n    Fecha de Creacion: 30 de Enero del 2013\n    Autor: Andrew J. Redican " );	
	        System.out.println( " \n\n    Bienvenido al Asterisco. \n    Por favor, ingrese los datos requeridos. \n \n " );
// Requesting values	
	        System.out.println( "Numero de columnas: ");
            c = sc.nextInt();
	        System.out.println( "Numero de lineas: ");
	        l = sc.nextInt();
// If any values are 0 then do nothing.  
			if ( c > 0 && l > 0 )
			{
 
				if ( c > 1 )
				{  
 
					while ( contern <= c )
					{
			            Aster = Aster + Aster;
						contern++;
					}
 
					for ( int k=1; k <= l; k++)
					{
			            System.out.println( Aster );	        	    
			        }
 
				else if ( c <= 1 )
				{
 
				    for ( int k=1; k <= l; k++)
					{
			            System.out.println( Aster );
				    }
 
				}
 
				Aster = "*";
 
        	}
 
            System.out.println( "\n Desea ejectuar el programa otra vez? S para Si, N para No: \n " );
 
		    r = sc.next().charAt(0);
 
        } while (r == 'S' || r == 's' );
//Closing message		
		System.out.println( " \n\n    Gracias por usar Asterisco.java :)\n\n\n\n\n\n" );	
 
	}
}

Another Doubt:

Am I able to add Strings?

For example:

String word;
word = "wa";

word = word + word;

If I can't do that I'll have to think another way of add a given number of times "*" next to each other and then print it in my program.


I hope you can give me a hand.

Go through, and for each opening curly brace, find its closing curly brace. Then do the opposite. You have a mismatch in there.

As for adding Strings, what happened when you tried?

@ KevinWorkman

Don't know since I haven't sorted out the first problem.

By the way, I looked into it closely, 3 times, earch curly brace has its opposite pair.

I think problem is because I am placing more than two instructions within the else if?

Sounds like I missed something REALLY basic in my java course.

I removed the { thats extra on the code. Still displaying an error;

Asterisco.java:42: error: 'else' without 'if'
else if ( c <= 1 )
^
1 error

Count again. You have 9 opening curly brackets, and only 8 closing brackets. One of them is missing its pair.

@ KevinWorkman

You were right about an extra { yes.


@ Zaphod_b

Thanks man!

I had to go over my book again.

Great help. I'll be placing the code for any bypassers that might have the same error/issue.

			            Aster = Aster + Aster;
						contern++;

			            System.out.println( Aster );

				else 
				    if ( c == 1 )
				    {
				        for ( int k=1; k <= l; k++)
					    {
			                System.out.println( Aster );
				        }
					}
				else ;
 
 
				Aster = "*";
 
        	}

I guess it was a sintax error. Programs works perfectly.
