Question

How can I get my Java code to print out 2 decimal places instead of 1? I can attach my code if necessary. I have a program that collects a peron's name, id number, how much they make an hour, and how long they worked. The system then prints out their information as:

first and last name, employee id ####, made $###.## in gross pay.

I have everything working but when it prints out that information it uses only 1 decimal place.

part of my code:

// this is my function to calculate the amount of money made.

public double grossPay()
{
return hours * rate;
}

**********************************************************************

then in the main method I declared all my other variables including:

double grossPay;

after declaring my variables, I have the system ask the user for their input.

and this is what I have for it to display back to the user:

System.out.println(pay.getName() + ", Employee Number: " + pay.getIdNumbers() +
", made $" + pay.grossPay() + " in gross pay.");

* How can I get the pay.grossPay() to display in 2 decimal places?

the question states to use text forming so that the gross pay is rounded to two decimal places.

Explanation / Answer

Hi, Please find the below updated statement for your requirement.

Two ways we can do this.

Option 1: By using Syste,.format method.

System.out.println(pay.getName() + ", Employee Number: " + pay.getIdNumbers() +
", made $" +String.format("%.2f", pay.grossPay()) + " in gross pay.");

Option 2: By using DecimalFormat

public double grossPay()
{

DecimalFormat df = new DecimalFormat("#.##");
return Double.valueOf(df.format(hours * rate));
}
