using an if statement to populate an array

[MrJinx]

I have an assigment to read through a text file and count the occurrence of a string. I thought I could populate an array with the matches and then show the size of the array, so I tried this:

ArrayList<Integer> numbers = new ArrayList<Integer>();
			  	String sourceFile = JOptionPane.showInputDialog("Enter the source file name: ");
			
			    
			  	if(sourceFile!=null){
			  	
			    FileInputStream data= new FileInputStream(sourceFile);
				BufferedReader data_in = new BufferedReader(new InputStreamReader(data));
				
				String str;

				while( (str = data_in.readLine() ) != null){
					if (str == "147628") {
						numbers.add(Integer.parseInt(str));
					    }

					
				}
	    	
		    JOptionPane.showMessageDialog(null, numbers.size());
			  	}

Could someone offer up a clue as to what I'm not getting?

You're using == to compare strings. Don't do this, because it compares object references instead of content. Use .equals() instead.

Thanks for the quick response. I'll try what you said Iron Lion. My result is 0 which is incorrect.

:) I suppose I should have tried it before my last post but that was it. I wish I found this site last night, I'm embarressd to say how long I played with this. My last challenge is to list a range of numbers. Thanks again.
