On a side note, when you use [code] tags the last tag should have a / before the word code inside the brackets.

Consider the following example: public class Test { public static void main(String[] args) { my_method(); public static void my_method() { System.out.println("Hello, world!"); } } 5 errors found: File: Test.java [line: 6] For example: public class Test { public static void main(String[] args) { String str = "Hello, world!"; String a = str.substring(-1, 3); String b = str.charAt(str.length()); String c = str.substring(0, 20); In this case, we simply need to add a curly brace to close the main method on the line before where the compiler issued the warning. The error message will tell you which character is missing and on which line.

public double pay(double x,int y){ int sum=0; double hours=8.0; if(y>hours){ sum=(y-hours)*(1.5*x) + (hours*x); } return sum; } Error: You have a mismatch between data types. For example, the call pay(5.50, 6) should return 33.0. Therefore, y cannot be printed; it needs to be initialized as x is in this example. In our example program above, notice that the two curly braces at the end of the program are at the same indentation level, which cannot happen in a valid program.

However, cases can also arise where it is clear to us that one of the cases has to be reached and therefore the error should not happen. Just change the data type of interest to what it should be, which is type double. Currently there is nothing implemented in the Catch portion. The next line of the error message (which says "found") tells you what you (incorrectly) tried to use to call the method.

if numOfMiles is an integer value of 1035 it would be multiplied by 1.75. get redirected here For example: public class Test { public static void main(String[] args) { int x; boolean setX = false; if (setX) { x = 10; } System.out.println(x); } } 1 error found: Possible loss of precision error in Java..? Ask on Piazza -- using the error folder.

cannot find symbol "Cannot find symbol" errors generally occur when you try to reference an undeclared variable in your code.

However, the first line lets you know that a problem with a String index was encountered, and the index in error was -1. here is my code for that method: public double calculateFuel(){ if (numofmiles<1000){ numofmiles = numofmiles*2; } else if (numofmiles>1000 && numofmiles<3000){ numofmiles = numofmiles*1.75; } else if (numofmiles>3000){ numofmiles = numofmiles*1.5; Browse other questions tagged java or ask your own question. navigate to this website and it is for free? 22 answers I have a Computer Science degree and I've copied and pasted code thousands of times in college.

When does bugfixing become overkill, if ever? For example: public class Test { public static void main(String[] args) { int value = twice(5); System.out.println(value); } public static int twice(int x) { int twice = 2 * x; return You have declared interest to be of type integer.

There is no slot number 9 3/4; that only exists in Harry Potter.

For example: public class Test { public static void main(String[] args) { my_method; } public static void my_method() { System.out.println("Hello, world!"); } } 1 error found: File: Test.java [line: 7] Error: So you need to convert the doubles to integers. But you are performing calculations that require a double, since your annualInterest is of type double and divided by 12 will pretty much always give you a decimal value similar to Write a method named pay that accepts a real number for a TA's salary and an integer for the number of hours the TA worked this week, and returns how much
