Exam 5: Methods

Assume that the following method header is for a method in class A. public void displayValue(int value) Assume that the following code segments appear in another method, also in class A. Which contains a legal call to the displayValue method?

When writing the documentation comments for a method, you can provide a description of each parameter by using a:

The lifetime of a method's local variable is:

When you pass an argument to a method, be sure that the argument's data type is compatible with:

A value-returning method must specify this as its return type in the method header.

Which of the following values can be passed to a method that has an int parameter variable?

All @param tags in a method's documentation comment must:

What will be returned from the following method? Public static int methodA() { Double a = 8.5 + 9.5; Return a; }

In the following code, Integer.parseInt(str), is an example of: int num; String str = "555"; Num = Integer.parseInt(str) + 5;

You must have a return statement in a value-returning method.

Given the following method header, which of the method calls would be an error? Public void displayValues(double x, int y)

Any method that calls a method with a throws clause in its header must either handle the potential exception or have the same throws clause.

A value-returning method can return a reference to a non-primitive type.

A parameter variable's scope is the method in which the parameter is declared.

This type of method performs a task and sends a value back to the code that called it.

This part of a method is a collection of statements that are performed when the method is executed.

Two general categories of methods are void methods and value returning methods.

Local variables can be initialized with:

When an object, such as a String, is passed as an argument, it is:
