(boolean expression) {statement(s) } where, boolean expression = anything that evaluates to true or false. One kind of boolean expression is the relational expression, which compares two quantities for one of these 6 relationships: =, ==, and != statement(s) = any number of Java statements

evaluation of boolean expressions (always) Example using && Consider the boolean expression A && B (where A and B are two boolean expressions) If A is false, does it matter what B is? (No, because false && anything is false) Therefore, Java will not evaluate B unless A is true. So, expressions such as the following are safe. x != 0 && y/x < z

3.2 The boolean Data Type. Most of the time when you deal with Booleans in a program, you are dealing with Boolean expressions. However, there are times when you want to save the value of a Boolean expression. In those cases, you will have to declare a boolean variable. Like this: boolean lightsOn = true; Summary of Relational Operators.

7 < 4 evaluates to the boolean value true. 1 is an int. booleans and ints cannot be compared in Java, because Java is a type-safe language. What is the result (if it does not cause a compiler error)? Compiler error,no result. 3 - -4 != 6 % 11. Will the expression cause a compiler error? What is the order of evaluation? (What groups are ...

The Boolean Data Type and Operations. Often in a program you need to compare two values, such as whether . i. is greater than . j. Java provides six comparison operators (also known as relational operators) that can be used to compare two values.

Relational and Boolean Expressions. Relational Expressions: has two operands and one relational operator. The value of a relational expression is Boolean, unless it is not a type included in the language. Use relational operators and operands of various types. Operator symbols used vary somewhat among languages (!=, /=, .NE., , #)
