    Question '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.
    Andrew R.

    Default Re: 'ELSE' missing 'IF'

    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?

    That's not an "issue," it is an error. Inconsistent use of spaces and tabs makes the appearance (to us mere humans) to be different than what the compiler sees. (In Java, the compile ignores indentation and uses {} braces to delineate blocks.)


    When I reformatted your code so that the visual alignment is consistent with the control structures, here's what I see. (I added a comment to show the problem line:
    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 ) // This is line number 42
                    {
     
                        for ( int k=1; k <= l; k++)
                        {
                            System.out.println( Aster );
                        }
    .
    .
    .

    Now does the error message make sense?


    Cheers!

    @ 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.

    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.

    .
    .
    .
     
    			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 );
    				        }
    					}
    				else ;
     
     
    				Aster = "*";
     
            	}
     
    .
    .
    .

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