Consider a method defined with the header: public static void doStuff(double a, int b)
Which of the following method calls is NOT legal?
int x = 9;
int y = 36;
doStuff (x, y);
doStuff (5.5, 7);
doStuff (5, 7);
doStuff (5, 7.5);
int z = 55;
doStuff (z, z + 1);
Consider the following variables and method representing a student.
private double gpa;
private int gradeLevel;

public boolean honorRoll()
{
/* Missing Code */
}
A student is placed on the honor role if their GPA is 3.5 or above, and they are in the 11th or 12th grade.
Which of the following correctly replaces /* missing code */ so that the method works as intended?
I. if ((gpa >= 3.5) && ((gradeLevel == 11) || (gradeLevel == 12)))
return true;
return false;
II. boolean pass = false;
if (gpa >= 3.5);
pass = true;
if ((gradeLevel == 11) || (gradeLevel == 12))
pass = true;
return pass;
III. if ((gpa >= 3.5) || ((gradeLevel == 11) || (gradeLevel == 12)))
return true;
return false;
I only
II only
III only
II & III
I, II, & III
When a parameter is a(n) data type, any changes made in a method are preserved.
int
binary
actual
class
primitive
What mistake is in the following code?
public static void mystery(double a) {
System. out. println(a * 3.14);
return a * 3.14;
}
It should say return true;
The return value should be a boolean.
The parameter should be a boolean type.
A method whose return type is void cannot return a value.
A method cannot return a double.
What return statement may be used in the following method?
public static int p() {
//...
}
return 1;
return {1, 2, 3};
return int[]{1, 2, 3};
return new int[]{1, 2, 3};
return p[1]
When you pass a double variable to a method, the method receives .
a copy of the memory address
the reference of the variable
the length of the variable
a copy of the variable
binary of the memory address
What is output by the following code?
String q = "onomatopoeia";
String r = "splat";
System. out. println( q. indexOf( r. charAt (3)));
