A1:Operator precedence in Java defines the order in which operators are evaluated in expressions. It ensures that expressions are processed correctly by establishing rules for the hierarchy of operators. Q2: How can I override operator precedence in Java? A2:Parentheses can be used to override the...

A primitive operator is written in C++ or Java™, whereas a composite operator is written in SPL and contains a reusable stream subgraph. An application can be viewed as a hierarchy of operator invocations, where the leaves are primitive operators, each level groups graphs of operators into co...
