Suppose 3 text Field first amount ,second amount and third sum of these amount,this amount will appear when tab in next filed(i don't want use any type button) in java swing HOW? PLEASE HELP
in textfield2 value change event you can write the code like
String s1,s2; s1=t1.gettext(); s2=t2.getText(); a=Integer.parseInt(s1); b=Integer.parseInt(s2); c=a+b; t3.text=c;
Please make sure that each text atleast contain value of 0. for making this you can give 0 value to all textfiled at design time itself....
