String to Float

[durahman]

I had been browsing the forum to get ideas from members.

I was trying to do some validations on input entered by users through a form. Validation involve say Input fields must not empty and one must be an Integer and one must be a float.

Field must not empty works fine.
One Input must be an Integer works fine.

Problem when come to float it seem my coding does not working the way I want it.

Here is part of the validation code:

Code:

public boolean validate() {

		boolean allOk=true;
		if (noreg_majikan.equals("")) {
			errors.put("noreg_majikan"," Perlu diisi.");
			noreg_majikan="";
			allOk=false;
		}

		if (bil_kosong.equals("")) {
			errors.put("bil_kosong"," Perlu diisi.");
			bil_kosong="";
			allOk=false;
		}else {
			try {
			      int x = Integer.parseInt(bil_kosong);
			     }
		     	      catch (NumberFormatException e) {
				errors.put("bil_kosong","Perlu dalam bentuk angka");
				bil_kosong="";
				allOk=false;
			   }	
		      }

		if (gaji.equals("")) {
			errors.put("gaji"," Perlu diisi.");
			gaji="";
			allOk=false;
		}else {
			try {
			       float y = Float.parseFloat(gaji);
			    }
		     	      catch (NumberFormatException e) {
				errors.put("gaji","Perlu dalam bentuk angka");
				gaji="";
				allOk=false;
		      	    }	
		     }

		return allOk;

	}

For the float part if the field not entered (empty) it give the correct message. If I enter a String it give the correct message.

When I entered 9 ( or any integer) it works. But when I entered say 99.50 it give error as if I had entered a String.

I just want to know why?

Thanx

[hey]

Did you try to enter 99,50 instead of 99.50?

I don't know, just guessing

Why don't you use Scanner? It should be much faster with it

When I tried it again it works.

99,50 it gives a String error.

Since I am new to java, I will explore the use of scanner.

Thanks Hey.
