When an expression contains multiple operators, it can potentially be read in different ways. For example, the mathematical expression 1 + 2 x 3 could be read in two ways: Add 1 and 2 and multiply the result by 3. This gives the answer 9. If we added parentheses, this would look like ( 1 + 2 )...

A constant expression is an expression that yields a primitive type or a String, and whose value can be evaluated at compile time to a literal. The expression must evaluate without throwing an exception, and it must be composed of only the following: Primitive and String literals. Type ca...

Java expressions are evaluated following the following rules: Operands are evaluated from left to right. The operands of an operator are evaluated before the operator. Operators are evaluated according to operator precedence Argument lists are evaluated from left to right. Simple Example I...

Expressions in Java are the primary construct for doing calculations. Here are some examples: 1 // A simple literal is an expression 1 + 2 // A simple expression that adds two numbers (i + j) / k // An expression with multiple operations (flag) ? c : d // An...
