    Default searching a string

    so for some reason it doesn't run even though i typed it as the book said to do

    import javax.swing.*;
     
    public class JProject3
    {
        public static void main(String[] args)
        {
    	    int k,m,x;
    	    String Bean;
    /*
            for (k=0; k<20; k++)
            {
                System.out.println("The values are\t" + ((k*2)-11));
    	    }
     
            System.out.println();
            System.out.println();
     
    	    for (k=0; k<20; k++)
    	    {
    			System.out.println("The values are\t\t" + ((k+1)*101));
    	    }
     
            System.out.println();
            System.out.println();
     
    	    m = 1;
    	    for (k=0; k<20; k++)
    	    {
    			if (m==1)
    			{
    				System.out.println("The Values are\t\t\t" + (Math.pow(10,(k+2))));
    		    }
    		    else
    		    {
     
    		        System.out.println("The Values are\t\t\t" + (Math.pow(10,k)));
    		        k=k-1;
    		    }
    		    m=m*(-1);
    		}
     
            System.out.println();
            System.out.println();
     
    		for (k=0; k<20; k++)
    		{
    			System.out.println("The Values are \t\t\t\t" + ((k+1)*(k+1)*(k+1)));
    		}
            System.out.println();
     
            x = 10;
            for (k=0; k<20; k++)
            {
            System.out.println("This works " + Math.round((1/Math.sqrt(5))*((Math.pow(((1+Math.sqrt(5))/2),k))-(Math.pow(((1-Math.sqrt(5))/2),k)))));
    	    }
    	    */
     
    	    Bean = JOptionPane.showInputDialog("Give me an input");
    	    if ( (searchStr(Bean,f)) == f)
    	    {
    			System.out.println("AWESOME");
    		}
    		else
    		{
    			System.out.println("Not Awesome");
    		}
     
        }
    }

    its at the very end of the code where im trying to search an input for f that im running into a problem with.

    Default Re: searching a string

    i'm betting theirs another function that u missed some where
    some times they leave pieces out so u have to read through and find
    the part that needs added

    also u did a LOT of useless typing
    the first part has no use at all , everything from "/*" to "* /" XD

    from the looks of the method call u need something like this
    public static string searchStr(String input,String search){
       if (input.contains(search)){
          return search;
       } else {
          return null;
       }
    }
