Decimal Fill up

[maya700]

Hey guys

Below mentioned is a simple program which i wrote that will decide how many digits to display after decimal place.


class Exercise1

{


public static void main(String[] args)

{

double d = 2344.5;

System.out.println("%.5f", d);

}

}

Now as per the above code the output should be 2344.500000, but instead of that i get an error

cannot find symbol, symbol: method println(java.lang.String.double)

location : class java.io.PrintStream

Can anyone help me out with this one????

System.out.println("%.5f", d);

You need the System.out.printf( ... ) method, not the System.out.println( ... ) method.

kind regards,

Thanks, that worked. So do i have to use printf every time i use %f or %someother????

Thank you.

Thank you.

You're welcome of course; read the API documentation for the PrintStream class (System.out is a PrintStream object). The print( ... ) and println( ... ) methods take a single argument while printf( ... ) takes many arguments and uses a Formatter to do the job. The API documents are your friend.

kind regards,
