In the Java programming language, any code between matching braces. Example: { x = 1; }. Read More

A module that alternately decodes and executes every statement in some body of code. The Java interpreter decodes and executes bytecode for the Java virtual machine1. See also compiler, runtime system. Read More

Refers to an expression or variable that can have only a true or false value. The Java programming language provides the boolean type and the literal values true and false. Read More
