What is an operator? Name any two types of operators used in Java.

An operator is a symbol that performs an operation on one or more values (operands) and produces a result. For example, in a + b the symbol + is an operator and a and b are its operands.

Two types: arithmetic operators (+, -, *, /, %) and relational operators (<, >, <=, >=, ==, !=).

Answer in two parts: the definition, then two named types with examples. Any two of these are acceptable — arithmetic, relational, logical (&&, | | , !), assignment (=, +=), unary (++, --), ternary (? :), bitwise. Naming the type without giving symbols usually costs half the mark, so always add an example or two.
