Operators and Expressions
Operators perform actions on values (operands), and expressions combine operators and operands to compute results in a Java program.
Core concept
Arithmetic operators, like +, -, *, /, and %, perform mathematical operations on numbers.
How it works
Relational operators, like ==, !=, <, >, compare values and return a boolean result (true or false).
Why it matters
Logical operators, like && (AND), || (OR), and ! (NOT), combine boolean expressions for more complex conditions.
Key detail
Understanding operators and expressions is essential for performing calculations and making decisions in Java programs.
