Cannot Be Resolved To A Variable Eclipse Debug
them; it only takes a minute: Sign up Java, “Variable name” cannot be resolved to a variable up vote 9 down vote favorite 1 I use Eclipse using Java, I get this error: "Variable name" cannot be resolved to string cannot be resolved to a variable java a variable. With this Java program: public class SalCal { private int hoursWorked; public SalCal(String name, int hours, double hoursRate) { nameEmployee = name; hoursWorked = hours; ratePrHour = hoursRate; } public void setHoursWorked() { hoursWorked = hours; //ERROR HERE, hours cannot be resolved to a type } public double calculateSalary() { if (hoursWorked <= 40) { totalSalary = ratePrHour * (double) hoursWorked; } if (hoursWorked > 40) { salaryAfter40 = hoursWorked - 40; totalSalary = (ratePrHour * 40) cannot be resolved to a variable error in jsp + (ratePrHour * 1.5 * salaryAfter40); } return totalSalary; } } What causes this error message? java variables name-resolution share|improve this question edited Sep 15 '13 at 3:47 Eric Leschinski 46.8k23221190 asked Sep 28 '11 at 19:50 user820913 1682615 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote accepted If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int) The two variables you are having trouble with are passed as parameters to the constructor. 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 46.8k23221190 answered Sep 28 '11 at 19:59 Hugh Jones 1,952620 add a comment| up vote 6 down vote public void setHoursWorked(){ hoursWorked = hours; } You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error. share|improve this answer edited Sep 15 '13 at 3:49 Eric Leschinski 46.8k23221190 answered Sep 28 '11 at 19:55 Marc B 273k24233352 add a comment| up vote 2 down vote I've noticed bizarre behavior with Eclipse version 4.2.1 delivering me this error: String cannot be resolved to a variable With this Java code: if (true) String my_variable

Cannot Be Resolved To A Variable Eclipse Jsp
variable error in Eclipse up vote 0 down vote favorite Trying to write a simple program that prints the Fibonacci sequence. I want to create a method named fibNumber that calculates the value of the Fibonacci sequence and then I want to use a http://stackoverflow.com/questions/7588784/java-variable-name-cannot-be-resolved-to-a-variable for loop in the run() method to print that value 15 times. The trouble I'm having is the println method in the for loop. Eclipse says "n cannot be resolved to a value" and "i cannot be resolved to a value." I thought I covered all the bases in terms of declaring the variables. Am I missing something? What I want to write is all the way up to F15 F0 = 0 F1 = 1 F2 = 1 F3 = 2 F4 = 3 F5 = http://stackoverflow.com/questions/13116940/cannot-be-resolved-to-a-variable-error-in-eclipse 5 import acm.program.*; public class FiccononicSequence extends ConsoleProgram { public void run(){ println("This program prints out the Fibonacci sequence."); for (i = 1; i <= 15; i++){ println("F" + i + " = " + fibNumber(n)); } } private int fibNumber(int n){ if (n == 0){ return 0; }else{ if (n == 1){ return 1; }else{ return fibNumber(n - 1) + fibNumber(n - 2); } java eclipse share|improve this question edited Oct 29 '12 at 6:43 asked Oct 29 '12 at 6:37 Jessica M. 61251943 I'm a little confused. How is println("F" + i + " = " + fibNumber(i)); contain the value of the method fibNumber? Won't it just print the increase in the value of i in the for loop? –Jessica M. Oct 29 '12 at 6:49 even after I change fibNumber(n) to fibNumber(i) Eclipse still gives me a "i cannot be resolved to a variable" error. I'm not sure what the error is. –Jessica M. Oct 29 '12 at 7:23 Check the AmitD, Quoi answers and mine. You lacked declarate the i variable as int. –Luiggi Mendoza Oct 29 '12 at 7:34 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote accepted Try this... - The problem here is about the scope of the variable. - i should be declared of type int, which is local to the run() method instead of n, as n is another local variable in fibNumber() method. - i and n are totally in different scope and are invisible to each

The https://www.youtube.com/watch?v=m27kp7VvlW4 entire code is here: pastebin.com but the mistake seems to be here, as this is the area which eclispe marks for (int i = 5; i < 60; cannot be i+= 4); { track.add(eventErzeugen(144,1,i,100,i)); track.add(eventErzeugen(176,1,127,0,i)); track.add(eventErzeugen(128,1,i,100,i + 2)); eclipse gives 5 errors, saying: Exception in thread "main" java.lang.Error: Unresolved compilation problems: i cannot be resolved to a variable My question is: what is wrong with the variable i??
