The error message is because 'hours' is out of scope in the setter. share|improve this answer edited Sep 15 '13 at 3:49 Eric Leschinski 46.1k23220190 answered Sep 28 '11 at 19:59 Hugh Jones 1,952620 add a comment| up vote 6 down vote public void setHoursWorked(){ hoursW

Talend Cannot Be Resolved To A Variable
minute: Sign up Java error message “Cannot be resolved to a variable”? up vote 3 down vote favorite ok so I'm kinda new to java and I'm trying to make a class which will be able to ask the user to http://stackoverflow.com/questions/7588784/java-variable-name-cannot-be-resolved-to-a-variable input a 12 digit long upc code, check to make sure its a valid code, and then display if it is or not. I've got quite a few errors with the current program that I have and I can't seem to figure it out. This is the code that I have so far: public class Upc { private long upc; public Upc(long upcs) { upc = upcs; } public long getUpc() { int m = (n2 + n4 + n6 + n8 http://stackoverflow.com/questions/8177913/java-error-message-cannot-be-resolved-to-a-variable + n10); long n = (n1 + n3 + n5 + n7 + n9 + n11); long r = (10 - (m + 3 * n) % 10); long n12 = (int) (upc % 10); upc /= 10; long n11 = (int) (upc % 10); upc /= 10; long n10 = (int) (upc % 10); upc /= 10; long n9 = (int) (upc % 10); upc /= 10; long n8 = (int) (upc % 10); upc /= 10; long n7 = (int) (upc % 10); upc /= 10; long n6 = (int) (upc % 10); upc /= 10; long n5 = (int) (upc % 10); upc /= 10; long n4 = (int) (upc % 10); upc /= 10; long n3 = (int) (upc % 10); upc /= 10; long n2 = (int) (upc % 10); upc /= 10; long n1 = (int) (upc % 10); if (r == n12) { return (upc + " is a feasible UPC code"); } else { return (upc + " is an invalid UPC code"); } } } and my errors are as follows: 13 errors found: File: C:\Users\Andrew\Downloads\Upc.java [line: 10] Error: n2 cannot be resolved to a variable File: C:\Users\Andrew\Downloads\Upc.java [line: 10] Error: n4 cannot be resolved to a variable File: C:\Users\Andrew\Downloads\Upc.java [line: 10] Error: n6 cannot be resolved to a variable File: C:\Users\Andrew\Downloads\Upc.java [line: 10] Error: n8 cannot be resolved to a variable File: C:\Users\Andrew\Downloads\Upc.java [line: 10] Error: n10 cannot be resolved to a variable
error and eclipse is telling me my finalAmount variable can't be resolved. From looking at it I know it's outside of the scoop of the for statement and everytime I create a local variable and assign https://teamtreehouse.com/community/java-cannot-be-resolved-to-a-variable a value to it (it's zero) my program gets messed up. My question is, how would I declare the finalAmount variable locally? Thanks import java.util.Scanner; public class CompoundInterest { public static void main(String[] args){ double rate; double amount; https://www.youtube.com/watch?v=FFw-PnSjqjE double year; System.out.println("This program, with user input, computes interest.\n" + "It allows for multiple computations.\n" + "User will input initial cost, interest rate and number of years."); Scanner input = new Scanner(System.in); System.out.println("What is the inital cost?"); cannot be amount = input.nextDouble(); System.out.println("What is the interest rate?"); rate = input.nextDouble(); rate = rate/100; System.out.println("How many years?"); year = input.nextDouble(); for(int x = 1; x < year; x++){ double finalAmount = amount * Math.pow(1.0 + rate, year); // the below works but the problem is, it prints the statement out many times. I don't want that. /* System.out.println("For " + year + " years an initial " + amount + " cost compounded at a rate cannot be resolved of " + rate + " will grow to " + finalAmount); */ } System.out.println("For " + year + " years an initial " + amount + " cost compounded at a rate of " + rate + " will grow to " + finalAmount); } } 1 Answer omars 9,006 Points omars omars 9,006 Points almost 3 years ago Shane, Q: "eclipse is telling me my finalAmount variable can't be resolved" A: This is because you are declaring 'finalAmount' within the for loop. Once your for loop exits, 'finalAmount' goes out of scope. Meaning, Java has no clue it ever existed. Q: "My question is, how would I declare the finalAmount variable locally?" A: From what I know, you cannot declare a variable within a loop of any kind if you want to retain the previous value. When you declare a variable within a loop this is what happens: Your loop begins with an initial value of 0. (This is before the calculation takes place, double finalAmount;) A value is calculated and assigned to finalAmount. Your loop ends. If you loop condition is still valid (x < year), repeat from step one (finalAmount is redeclared and initialized). Someone please correct me if I said anything wrong about the above steps. Here is my suggested change to your code, I hope this helps. im
