AP Computer Science A Notes: AP CS A concerns _______-__________ programming. object-oriented Related classes in java are grouped into... packages A Java program must have at least ___ class(es). 1 The java files that comprise your program are called... source files A __________ converts source code into a machine readable form. compiler A compiler converts source code into a machine readable form, called... bytecode All Java methods must be contained in a(n)... class All program statements must be placed inside a(n)... method The keyword _____ signals that the class or method is usable outside the class. public The keyword ____ signals data or methods are not usable outside the class. private The keyword ________ is used for methods that will not access any objects of a class. static The ________ method must always be static. main A(n) ____ is a name for a variable, parameter, constant, user-defined method, or user-defined class identifier An identifier may use... (3) letters, digits, and underscores Identifiers may not begin with a(n)... digit What primitive types are included in the AP Java subset? (4) int, boolean, double, char If you try to store a value that is too big in an int variable, you'll get a(n).... overflow error When you get an overflow error, does Java give you a warning? no Assigning a double to an int will cause a(n)... compile-time error A(n) ________ variable is used to name a quantity whose value will not change. final True or false: constant identifiers are capitalized. true What purpose does using constants serve? it makes it easier to revise the code _____________ operators are used in boolean expressions. relational Relational operators should generally only be used when comparing...A method that performs an operation for the entire class, not its individual objects, is called a(n)... static method All methods defined in the main program must be... static ________ methods are two or more methods in the same class that have the same name but different parameter lists. overloaded primitive types Avoid using boolean operators to compare ______-______ numbers. floating-point _________ operators are applied to boolean expressions to form compound boolean expressions. Logical Operators such as +=, =, -=, and /= are known as __________ operators. compound assignment True or false: when chain assignments like the following are used: x = y = z = 0; the statement is evaluated from left to right. false Is the following order of operator precedence correct? 1) !, ++, -2) *, /, % 3) +, 4) <, >, <=, >= 5) ==, != 6) && 7) || 8) =, +=, -=, *=, /=, %= yes What will be the output of the following statement? System.out.println( 5 + 3 < 6 - 1 ); false
