You covered all the operators you need to write real Java programs. Arithmetic operators (+, -, *, /, %) handle math, with the catch that integer division truncates. Compound assignment (+=, -=) and increment (++, --) shorten common patterns.
Comparison operators (==, !=, <, >) produce boolean results, and you learned to always use .equals() for strings instead of ==. Logical operators (&&, ||, !) combine conditions, with short-circuit evaluation protecting you from runtime errors.
You also saw how operator precedence determines evaluation order, and how parentheses let you override it. Next, you'll put these operators to work inside control flow statements.
