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

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 (%).

Or You can use DecimalFormat display an output of float data with 2 decimal places in java. 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.
