10 Most Common Mistakes Every Beginner Makes

Surprisingly, it was found that most common programer mistakes were actually a result of common misconceptions based on loose evidence. Here are the top 10 errors made by beginner programmers:

  1. Unbalanced parentheses, curly braces, brackets, and quotation marks, or using these different symbols interchangeably, such as in: while (a == 0].
  2. Invoking methods with wrong arguments or argument types, such asin:list.get("abc").
  3. Control flow can reach end of non-void method without returning, such as in:

  4. Confusing the assignment operator (=) with the comparison operator (==), such as in: if (a = b).
  5. Ignoring or discarding the return value of a method with non-void return type, such as in: myObject.toString();.
  6. Use of == instead of .equals to compare strings.
  7. Trying to invoke a non-static method as if it was static, such asin:MyClass.toString();.
  8. Class claims to implement an interface, but does not implement all the required methods, such as in: class Y implements ActionListener { }.
  9. Invoking the types of parameters when invoking a method, such as in:myObject.foo(int x, String s);.
  10. Incorrect semicolon in if statements or for and while loops, such as in: if (a==b); return 6;.
