double degrees =si.nextDouble();

double degrad = (degrees * PI)/180.0;

System.out.println(“Degrees in radians with outFormatting:” + degrad);

NumberFormat numfrmt = NumberFormat.getNumberInstance();

// format the number

numfrmt.setMaximumIntegerDigits(2);

numfrmt.setMaximumFractionDigits(2);

//convert to to string and display

String stg = numfrmt.format(degrad);

System.out.println(“Degrees in radians with Formatting using “+stg);

}

Output: Enter angle in degrees:180
