Arguments to methods always appear within __________.
parentheses
You should fill in the blank in the following code with \_\_\_\_\_\_\_\_\_\_\_\_\_\_.
public class Test {
public static void main(String[] args) {
System.out.print("The grade is ");
printGrade(78.5);
System.out.print("The grade is ");
printGrade(59.5);
}
public static \_\_\_\_\_\_\_\_\_\_ printGrade(double score) {
if (score >= 90.0) {
System.out.println('A');
}
else if (score >= 80.0) {
System.out.println('B');
}
else if (score >= 70.0) {
System.out.println('C');
}
else if (score >= 60.0) {
System.out.println('D');
}
else {
System.out.println('F');
}
}
}void
Consider the following incomplete code:
public class Test {
public static void main(String[] args) {
System.out.println(f(5));
}
public static int f(int number) {
// Missing body
}
}
The missing method body should be \_\_\_\_\_\_\_\_.return number;
Which of the following should be defined as a void method?
Write a method that prints integers from 1 to 100.
Which of the following is the best for generating random integer 0 or 1?
(int)(Math.random() + 0.5)
Suppose your method does not return any value, which of the following keywords can be used as a return type?
void
Each time a method is invoked, the system stores parameters and local variables in an area of memory, known as _______, which stores elements in last-in first-out fashion.
a stack
_________ is a simple but incomplete version of a method.
stub
Analyze the following code:
public class Test {
public static void main(String[] args) {
System.out.println(xMethod(5, 500L));
}
public static int xMethod(int n, long l) {
System.out.println("int, long");
return n;
}
public static long xMethod(long n, long l) {
System.out.println("long, long");
return n;
}
}The program displays int, long followed by 5.
(int)(Math.random() * (65535 + 1)) returns a random number __________.
between 0 and 65535
Does the method call in the following method cause compile errors?
public static void main(String[] args) {
Math.pow(2, 4);
}
no
Does the return statement in the following method cause compile errors?
public static void main(String[] args) {
int max = 0;
if (max != 0)
System.out.println(max);
else
return;
}no
You should fill in the blank in the following code with \_\_\_\_\_\_\_\_\_\_\_\_\_\_.
public class Test {
public static void main(String[] args) {
System.out.print("The grade is " + getGrade(78.5));
System.out.print("\nThe grade is " + getGrade(59.5));
}
public static \_\_\_\_\_\_\_\_\_ getGrade(double score) {
if (score >= 90.0)
return 'A';
else if (score >= 80.0)
return 'B';
else if (score >= 70.0)
return 'C';
else if (score >= 60.0)
return 'D';
else
return 'F';
}
}char
All Java applications must have a method __________.
public static void main(String[] args)
The signature of a method consists of ____________.
method name and parameter list
When you invoke a method with a parameter, the value of the argument is passed to the parameter. This is referred to as _________.
pass by value
What is k after the following block executes?
{
int k = 2;
nPrint("A message", k);
}
System.out.println(k);k is not defined outside the block. So, the program has a compile error
__________ is to implement one method in the structure chart at a time from the top to the bottom.
Top-down approach
