[Q#2538787][A#2538803] How to display an output of float data with 2 decimal places in Java?

Can I do it with System.out.print?

Answer

You can use the printf method, like so: In short, the %.2f syntax tells Java to return your variable (val) with 2 decimal places (.2) in decimal representation of a floating-point number (f) from the start of the format specifier (%). There are other conversion characters you can use besides f:

System.out.printf("%.2f", val);
