2. Omitting parentheses around method arguments when not appropriate
Better use paranetheses parentheses for argument lists unless you are sure.
For instance, a left paranthesis parenthesis after a method name must always enclose the parameter list.
This may cause the compiler to to assume a complete statement although it is meant as continuing in the next line. It is not always as obvious as in the following Exampleexample.
myVariable = "This is a very long statement continuing in the next line. Result is=" + 42 // this line has no effect
