Consider the following method: public a(String s) { int v = 0; for(int x = 1; x < s.length; x=x+1) { if(s[x] == 'a' || s[x]=='e' || s[x] == 'i' || s[x] == 'o' || s[x] == 'u') { v = v + 1; } } return v; } Exactly how many lines of code (statements) are executed by the method a() in the worst case?    Express your answer in terms of n, the length of the string s. Hint:  simplify your final answer as much as possible, and do not put spaces in your answer.  Use juxtaposition for the multiplication operator, for example to write "nine times n" write "9n" not "9xn" or "9*n";  to write "four times (n+2)" write "4(n+2)", not "4x(n+2)" or "4*(n+2)".  Do not write your answer in Big-O notation.  Write the exact number of lines executed.

1. When you run the following code, what would happen?public class Question1 {public static void main(String arg[]){int i;int [] A = new int[10];int count = 0;int temp = 10;for (i=0; i < A.length; i++)if (A[i] < temp) count++;System.out.println(count);}}(a) It finds the smallest value and stores it in temp.(b) It finds the largest value and stores it in temp.(c) It counts the number of elements equal to the smallest value in list.(d) It counts the number of elements in list that are less than temp.

Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. /** * Returns a String representation of this vector. The String should be in the format "[1, 2, 3]" * * @return a String representation of this vector * @apiNote **DO NOT** use the built-in (@code Arrays.toString()} method. */…

Consider the following piece of code. (The numbers on the left margin denote line numbers.) line#01 public class funcRef {02     private int n;03     public funcRef (int m) {n = m;}04     public static void func (funcRef t) {t.n++;}05     public static void main (String [] args) {06         funcRef t1, t2;07         t1 = new funcRef(20);08         t2 = t1;09         System.out.print(t2.n);10         func(t1);11         System.out.print(t2.n);12         func(t1);13         System.out.print(t1.n);14         func(t2);15         System.out.print(t1.n);16         func(t2);17         System.out.print(t1.n);18         System.out.print(t1.n);19         return;20     }21 } Out of the following, tick the true statements and leave the false statements unticked.(More than one of the statements could be true. You get full marks only for marking all the statements correctly. There are no partial marks.) A. The output of the program will be 202022222222. B. When func(t1) is called in line…
