Question
True or False (Java)
1) the modulus operator returns the remainder of integer division
2) all java variables are local to a method
3) the state of an object can change
4) accessor methods have a return type of non-void
5) java packages can be useful when writing a complex, real-world program.
6) when using for each loop, there is no explicit index.
7) infinite loops are never desirable to have in your code
8) for each loops are safer than while loops because for each loops have no explicit index
9) to initialize a variable is to set it to an initial value
10) more compact code is less likely to become buggy over time than less compact code--assuming it is not too compact to understand
11) in real-world Java projects, scalability and reusability of code are important benefits to consider
12) java packages make it easier to abstract away the details of how the packages are implemented, i.e. encapsulate the details
13) code with variable names balance and credit is more maintainable than code with variable names X and Y.
14) the bluej debugger is useful for setting breakpoints, examining variables, and stepping through into code.
