    Default if statement being ignored

    The variable "raise" isn't classed as initialised despite trying to do so in the nested "if" statements. This is an exercise for university where all we're supposed to do is add the necessary if statements to get it to work. The if statements are ignored no matter what I do. What am I doing wrong?
    Here is the code with the if statements I entered.

    package selectionIteration;

    import java.util.Scanner;
    import java.text.NumberFormat;

    public class Raise {
    public static void main (String[] args)
    {
    double currentSalary; // employee's current salary
    double raise; // amount of the raise
    double newSalary; // new salary for the employee
    String rating; // performance rating

    Scanner scan = new Scanner(System.in);

    System.out.print ("Enter the current salary: ");
    currentSalary = scan.nextDouble();
    System.out.print ("Enter the performance rating (Excellent, Good, or Poor): ");
    rating = scan.next();

    // Compute the raise using if ...

    if (rating == "Excellent")
    raise = currentSalary * 0.06;
    if (rating == "Good")
    raise = currentSalary * 0.04;
    if (rating == "Poor")
    raise = currentSalary * 0.015;

    newSalary = currentSalary + raise;

    // Print the results
    NumberFormat money = NumberFormat.getCurrencyInstance();
    System.out.println();
    System.out.println("Current Salary: " + money.format(currentSalary));
    System.out.println("Amount of your raise: " + money.format(raise));
    System.out.println("Your new salary: " + money.format(newSalary));
    System.out.println();
    }
    }

    Default if statement being ignored

    I am working on adding code for an exercise at university where we have to add if statements to complete the code, but the 3 nested if statements are being completely ignore, and whatever I initialise "raise" as in the code, it just adds the initialised value at the end of the code instead of the modifications attempted in the if statements. This is the code, I only added the if statements.

    package selectionIteration;

    import java.util.Scanner;
    import java.text.NumberFormat;

    public class Raise {
    public static void main (String[] args)
    {
    double currentSalary; // employee's current salary
    double raise; // amount of the raise
    double newSalary; // new salary for the employee
    String rating; // performance rating

    Scanner scan = new Scanner(System.in);

    System.out.print ("Enter the current salary: ");
    currentSalary = scan.nextDouble();
    System.out.print ("Enter the performance rating (Excellent, Good, or Poor): ");
    rating = scan.next();

    // Compute the raise using if ...
    if (rating == "Excellent")
    raise = 0.06 * currentSalary;
    if (rating == "Good")
    raise = 0.04 * currentSalary;
    if (rating == "Poor")
    raise = 0.015 * currentSalary;

    newSalary = currentSalary + raise;

    // Print the results
    NumberFormat money = NumberFormat.getCurrencyInstance();
    System.out.println();
    System.out.println("Current Salary: " + money.format(currentSalary));
    System.out.println("Amount of your raise: " + money.format(raise));
    System.out.println("Your new salary: " + money.format(newSalary));
    System.out.println();
    }
    }


    Any help will be greatly appreciated. It seems like it should have been really simple to complete. Apparently not lol.

    Default Re: if statement being ignored

    The if statement is not being ignored. The problem is that the value of the expression in the if statement is always false.
    Use the equals method to compare the contents of String objects, not the == operator.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
