Please help. Assignmentoperator Expression

[zmstevens]

I am a first time user to Java and I am stuck and cant figure out what to do.. Please help. My code is

import java.util.Scanner;
public class rshomework2
{
  
  public static void main ( String[] args)  
  {
   Scanner input = new Scanner(System.in);
   sales;
   final double base = 800;
  
   System.out.println("Enter sales total");
     sales = input.nextDouble();
    
    // Calculate the amount of commission.
 commission = rate * sales;
    
 if (sales < 2999.99)
 rate = 0.02; // 2% commission rate
 else if (sales < 4999.99)
 rate = 0.03; // 3% commission rate
 else if (sales < 8999.99)
 rate = 0.04; // 4% commission rate
 else if (sales < 10999.99)
 rate = 0.05; // 5% commission rate
 else
 rate = 0.06; // 6% commission rate

  // Calaulate the amount of Salary.
    Salary = commission + base;
   
  // output values
   System.out.println ( "Gross Salary is $" + Salary);
   
  }
}

when I try to compile it says error line 12 syntax error, insert assignmentOperator Expression to complete expression. Please help.

Define your variable.... Most of your variables are not defined.

Ex in line 8 you have simply written

sales;

You should define it ex :

Double sales;

Likewise check all............

now is says variable reate may not have been initialized. I really do not know what I am doing.

[zmstevens]

import java.util.Scanner;
public class rshomework2
{

public static void main ( String[] args)
{
//read in pay
Scanner input = new Scanner(System.in) ;
double sales;
double commission;
double rate; // Commission rate
double Salary;
final double base = 800;

System.out.println("Enter sales total");
sales = input.nextDouble();

if (sales <= 2999.99)
rate = 0.02; // 2% commission rate
else if (sales <= 4999.99)
rate = 0.03; // 3% commission rate
else if (sales <= 8999.99)
rate = 0.04; // 4% commission rate
else if (sales <= 10999.99)
rate = 0.05; // 5% commission rate
else
rate = 0.06; // 6% commission rate

// Calculate the amount of commission.
commission = rate * sales;

// Calaulate the amount of Salary.
Salary = commission + base;

// output values
System.out.println ( "Gross Salary is $" + Salary);

}
}

So I got it to work. However when it gives me an answer it comes out like 949.9997. How do I make it only give two places after the decimal?

Use Decimal Format Class....

DecimalFormat df = new DecimalFormat("#.##");
df.format(doubleValues) // Return a String

Since it is a double you get it like that. However if you really need to round off to 2 decimal places. What you could is that like the below pseudo code

Define an int
Assign the answer*100 to the int (say X) as this will evade all the decimal there on.
Then define another double and assign the value of the X/100 which will give your required out put.
