    Default IF statement/Array

    /* *****************************************

    import java.util.Arrays;
    import javax.swing.*; // import the swing library for I/O
     
    class painting
    {
     
     
     
     
    	public static void main (String[] args)
    	{
     
    		vote();
    		System.exit(0);
     
    	} 
     
     
    	public static void vote()
    	{
    		String[] paintings = {"Mona Lisa","Water Lilies","The Scream","A Young Rembrandt"}; 
    		int[] scores = {0,0,0,0}; 
    		String painting;
     
    		for (int y=0; y<paintings.length; y++)
    		{
    			System.out.println("Vote "+ y + " for " + paintings[y]);
    		}
     
     
    		for (int i=0; i<paintings.length; i++)
     
    		{
     
    			painting = JOptionPane.showInputDialog("Which painting would you like to vote for?");
    			System.out.println(Arrays.toString(paintings));
     
    			if (paintings[i].equalsIgnoreCase(painting))
    			{
    				JOptionPane.showMessageDialog(null, "You voted for " + painting);
    				scores[i] = scores[i] + 1;
    			}	
    			else if(painting.equals("-33"))
    			{
    				for(int z=0; z<paintings.length; z++)
    					System.out.println((scores[z] + " " + paintings[z]));
    			}
    			else 
    			{
    				JOptionPane.showMessageDialog(null, "Invalid Entry");
     
    			}
     
    		}
     
    	}	
     
    }

    Why does my program skip the IF statement and just goes to the else part and prints "Invalid Entry" even when i enter a correct painting :S

    Default Re: IF statement/Array

    goes to the else part
    That means the condition in the if() was false.
    Print out the values of the variables used in the if condition to see why the if is never true.
    Be sure to add delimiters any Strings printed so you know if there are leading or ending spaces:
    println("theString="+theString+"<")
    If you don't understand my answer, don't ignore it, ask a question.
