Which of these methods can be used to check whether the given value is a number or not? i) isNaN() ii) isNumber() iii) checkNaN() iv) checkNumber()

task_6 Change Summation Integers problem to Finding the minimumproblem. Make sure you properly wrote/updated all text messages, method names,and math calculations.Hint: You can use java.lang.Math.min() method.Example: System.out.printf("The min of the integers %4d and %4d and %4dis %7d\n", a, b, c, MinTest(a, b, c));Submit the source code files (.java files) and the console output screenshots

Question #4: Re-write the program of Question #3 using data files. The input data numbers.txt contains (positive) integer numbers. Each time the program reads a number, check whether it is a prime and stores the result in the output file Results.txt. 373 373 is Prime!! 11 11 is Prime!! 2552 is NOT prime!! 5 is Prime!! 3561 is NOT prime!! 2552 3561 numbers.txt Results.txt

True or False: (a) In a debugger, we can choose whether to step into, step over, or step out of a particular method call. (b) Debuggers, tests, and println() statements are all legitimate ways to help us find errors in our code.

Python Programming ONLY PLEASE NO JAVA  Use recursion to determine the number of digits in an integer n.  Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10.  Write the method and then write a test program to test the method Your test program must:   Ask the user for a number Print the number of digits in that number. (describe the numbers printed to the console) Use program headers and method header comments in your code.

Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n)   public String repeatString(String str, int n) { //declare a string variable   //set up statements for repeating n number of times         //create the appropriate return statement   }

Java - How many recursive calls will be made if the following method is called with 6? void greeting(int n) {             system.out.println(“Hello!”);             greeting(n-1); }
