1. Consider the following class: public class Identify MyParts { public static int x = 7;....
In the following program: public class Problem2{ public static int sample(int x, int y){ int z; ...... } public static void main(String[] args) { int a, b; ...... sample(a,b); } } (1) What is the return type of sample? (2) What are the local variables of sample? (3) What are the parameters of sample? (4) What are the arguments of sample? (5) Is sample a per-object method? Or a per-class method? (6) Is sample a public method, or private method?
ndicate the correct answers bases on the following code: public class IdentifyMyParts { public static final int X = 7; public int y ; public void display(){.......} } public static void main(){string [] args){ IdentifyMyParts Obj1; Obj1.X=8; Obj1.y=20; } a. IdentifyMyParts is a class b. X is a instance method c. y is an instance variable d. Obj1.X=100; e. Obj1.y=200; f. display() is a member function
output What is the output of the following: class Access public int x; private int y public void cal(int x, int y) { this.x = x + 1; this.y = y; } public void print() { System.out.print(""+y); } } class AccessSpecifier { public static void main(String args[]) { Access obj = new Access(); obj.cal(2, 3); System.out.print(obj.x); obj.print(); } } 33 Compilation error 23 None of the available choices Runtime error
please evaluate the following code. this is JAVA a. class Car { public int i = 3; public Car(int i) { this.i = i; } } ... Car x = new Car(7), y = new Car(5); x = y; y.i = 9; System.out.println(x.i); b. class Driver { public static void main(String[] args) { int[] x = {5, 2, 3, 6, 5}; int n = x.length; for (int j = n-2; j > 0; j--) x[j] = x[j-1]; for (int j...
1) In the Quiz class, the foo method has the following API: public void foo( int x, String s) Which method call(s) would be correct assuming both a and y are integer values and assuming each statement is complete? a. Quiz q = new Quiz(); a = q.foo( y, “Maybe?” ); b. Quiz q = new Quiz(); q.foo( 1, “Hmmm!” ); c. Quiz q = new Quiz(); Quiz.foo( y, “You think” ); d. Both b and c 2) In the...
b) Consider the following code. public static int f(int n) if (n == 1) return 0; else if (n % 2 == 0). return g(n/2); else return g(n+1); public static int g(int n) int r = n % 3; if (r == 0) return f(n/3); else if (r == 1) return f(n+2); else return f(2 * n); // (HERE) public static void main(String[] args) { int x = 3; System.out.println(f(x)); (1) (5 points) Draw the call stack as it would...
