Hi Raja,

Thanks for the reply.

I have written the following UDF with the argument as input but it is giving the error with the empty processing log

Input Variable = String input

input=input.replaceAll(" ","");

// checking for null or spaces,if found return 0

if ((input.length() == 0) || ( input == "") )

return ""+0;

else{

Integer x = new Integer(input);

return x.toString();

}

Can you please help me?

Thanks in advance.

Try this code,

pass your string value as a string argument,just say valriable name Str1

int Str2 = Integer.parseInt(Str1);

return Str2;

above two lines of code enought.

Hi Raja,

I used the UDF and passed the argument as Str1 type String,

But I got the following error

incompatible types found : int required: java.lang.String return Str2;

Can you please help me?

Thanks in advance

Hi,

Use like this

int Str2 = Integer.parseInt(Str1);

return ""+Str2;

But i wonder y u req this UDF... taking string.. converting to int... returning as again a string...

Hi Swetha,

Please use the Function below to get the result :

//--- Utility function to get int using a dialog.

public static int getInt(String mess) {

int val;

while (true) { // loop until we get a valid int

String s = JOptionPane.showInputDialog(null, mess);

try {

val = Integer.parseInt(s);

break; // exit loop with valid int >>>>>>>>>>>>>>>>>>>>>>

}catch (NumberFormatException nx) {

JOptionPane.showMessageDialog(null, "Enter valid integer");

}

}

return val;

}//end getInt

I have not tested the function ,so just let me know if it is working or not.

Hi Shweta,

Use this below one line code, that's enough.

return (Integer.parseInt(str1)); // Here str1 is the input variable.
