Given the following code: public static void foo3(String s) { if (s.length() >0) { System.out.print(s.charAt(s.length() -1)); foo3(s.substring(0, s.length() -1)); } } What is the output of: foo3(“”); 2, You coded the following in the file Test.java : System.out.println( foo(5)); //more code here public static int foo(int n) //line 9 { if (n = = 0) return 1; else System.out.println(n* foo(n-1) ); } //line 15 At compile time, you get the following error: Text.java: 15: missing return statement } ...
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...
(20 pts) Fill in the missing code: This recursive method returns “even” if the length of a give String is even, and “odd” if the length of the String is odd. public static String foo(String s) { if (s.length() ==0) return “even”; else if (s.length() = = 1) return “odd”; else //your code goes here } (40 pts) You coded the following in the file Test.java : System.out.println( foo(5)); //more code here public static int foo(int n)...
(b) Trace the following code. // Precondition: n > 0 // <method description here> public static int dothing (int n) { int ans = ; for (int x 1; x <= n; x++) ( for (int y = x; y <= n; y++) ( ans+ } return ans; } (ii) If you were asked to write a one-line description above this method, what would it be? (iii) Could you rewrite the method so that it runs more efficiently?
Java code about writing two methods: public static String randomStringone(int length) public static String randomStringtwo(int length) This method should return a String of random lowercase letters with the given length by using for loops. To generate a random lowercase letter, use a local Random variable and the method nextInt() to generate a number between 97 and 122, then cast the result to a char. The method nextInt() can be found here: https://www.geeksforgeeks.org/java-util-random-nextint-java/ In randomStringone(), you should use String concatenation...
I need a java flowchart for the following code: import java.util.*; public class Main { public static void main(String[] args) { Scanner sc=new Scanner(System.in); System.out.print("Enter the input size: "); int n=sc.nextInt(); int arr[]=new int[n]; System.out.print("Enter the sequence: "); for(int i=0;i<n;i++) arr[i]=sc.nextInt(); if(isConsecutiveFour(arr)) { System.out.print("yes the array contain consecutive number:"); for(int i=0;i<n;i++) System.out.print(arr[i]+" "); ...
