Document Summary

Relational operators are > which compares whether one value is greater than the other : for example, int x = 3, int y = 2 ; if we use x > y then it returns true. If we use x < y then it returns false. >= : this operator greater than or equals to compare whether one value is greater than or equal to other value. For example, int x =5 ,y = 5, x>=y returns true because x is not greater than y but x is equal to y. X <= y so it also returns true. == this operator checks if the values of two variables are equal or not. It is not same as single = operator because it is used to assign value to a variable which == compares values of two variables. For example: int a = 3, int b = 3 when we say a == b then it returns true.

Coding Question - Sorted array You are to write a method that takes as input an array of integers, returns true if the array is sorted, and returns false otherwise. For example, if a is the array {1,12,5,6,2,87}, then the method has to return false as it is not sorted. Use the 5 following questions to "write" your code. Pay close attention to how your answers group together with each other. 33. Line 1 (A) public static boolean Sorted (int[] a) { (B) public static void Sort (int[] a) { (C) public static int[] Sorted (int a) { (D) public static boolean Sorted() { (E) public static void main(String[] s) {

Write a program called Lab 5 that has 3 methods and a main method:
1) Method isUserNameValid has 1 parameter of type string and the method returns a value of type
boolean. If the parameter has less than 8 characters then the method returns false, otherwise it
returns true.
2) Method compare has 3 parameters all of type int and has a String return type. This method will
return
a. “All Same” if all 3 parameters are equal,
b. “All Different” if all 3 parameters are different.
c. “Mix number(s)” two of the numbers are the same and the 3rd is different.
3) Method isValid has 1 parameter of type int and returns a boolean value; the method returns true if
the parameter is in the range 0,…,100 inclusive, otherwise the method returns false.
4) Main method. I want you to test methods isValid & isUsernameValid one time with a valid data
and another time with an invalid data. As for method compare test it 3 times so you can get the 3
different possible outcomes.
Example to test the isUserNameValid method

Longer multiple choice questions (3 points each) Coding Question - Fibonacci sequence You are to write a method named "Fibo" that takes as input an integer n, and returns the nth number in the Fibonacci sequence. If Fibo (n) denotes the nth number in the Fibonacci sequence, then recall for n > 2, Fibo (n) = Fibo (n-1) + Fibo (n-2), and Fibo (1) = 1 and Fibo (2) = 1. You are to assume that the user is always going to enter an input greater than 2. For example Fibo (4) = 3. Use the 7 following questions to "write" your code. Pay close attention to how your answers group together with each other. 26. Line 1 (A) public static int Fibo (int n) { (B) public static void main(String[] args) { (C) public static int Fibo () { (D) public static void Fibo (Double input) { (E) public static void Fibo (int n) {
