Programmers frequently make errors regarding the precedence of operators because of the unintuitive low-precedence levels of {{&}}, {{\|}}, {{\^}}, {{<<}}, and {{>>}}.

The precedence of operations by the order of the subclauses are defined in the Java Tutorials \[[Tutorials 2008|AA. Bibliography#TutorialsReferences#Tutorials 08]\]. |
