How can we display an output of float data with 2 decimal places in java Please help

Question

Can I do it with system.out.println?

Answer 1

You can use the printf method, for example:

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

 The %.2f syntax tells Java to return your variable (value) with 2 decimal places (.2) in decimal representation of a floating-point number (f) from the start of the format specifier (%).

Answer 2

Use String.format()  if you need the value as a String in your code.

For example, you can use String.format() in the following way:

float myFloat = 2.001f;

String formattedString = String.format("%.02f", myFloat);

Answer 3

String strDouble = String. format("%. 2f", 1.23456); This will format the floating point number 1.23456 up-to 2 decimal places, because we have used two after decimal point in formatting instruction %.

Answer 4

You can use DecimalFormat. One way to use it:

DecimalFormat df = new DecimalFormat();
df.setMaximumFractionDigits(2);
System.out.println(df.format(decimalNumber));

Another one is to construct it using the #.## format.

I find all formatting options less readable than calling the formatting methods, but that's a matter of preference.
