Question

please help me with java

we have to design an application that will calculate gross salary where basic salary is input through keyboard DA is 65% of basic salary. HRA is 45% of basic salary and TA is $10.

@experimentX

Answer 1

?? DBMS or what??

Answer 2

we have to design this program in java

Answer 3

some stuff like
float bs, da, hra, ta, gs;

Answer 4

do you have an alogrithm??

Answer 5

float bs, da, hra, ta, gs;
bs= float.parsefloat(bs.setText(""));
da= float.parsefloat(bs.getText());
da= bs* 65/100;
da.setText(""+bs*65/100);

Answer 6

you are taking input from a form??

Answer 7

seems all right ...

Answer 8

but i'm not getting why we are taking float?

Answer 9

probably because you need to calculate in decimals

Answer 10

but can we use double instead of float?

Answer 11

both represents fractional no.

Answer 12

sure ... if you want more precise.

Answer 13

but ... i think that's unnecessary
da= bs* 65/100;
da.setText(""+bs*65/100);

either do

da= bs* 65/100;
da.setText(""+da);

or

da.setText(""+bs* 65/100);


is da your input field?

Answer 14

no the input field is basic salary bs

Answer 15

oh ... just do this
da.setText(""+bs* 65/100);

It's been a quite a lot since i programmed java.

Answer 17

@vdidit : but i'm not getting why we are taking float?
Ans: Double are generally used when one need the precision they provide. Also they take more memory and are slow in calculation. Where as Float are faster. For performance critical applications Integers are used in decimal calculation as they have least overhead in comparison to float and double .
Float are faster than double for calculations. Read this article, where author compares performance of double against float in matrix multiplication for a nural network application.
