a) FindMinIterative
public int FindMin(int[] arr) { int x = arr[0]; for(int i = 1; i < arr.Length; i++) { if(arr[i]< x) x = arr[i];
} return x; }
b) FindMinRecursive
public int FindMin(int[] arr, int length) { if(length == 1) return arr[0];

Basic Java Help
Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names.
To start, implement the following class: baby names util = printTopNames(File, int): void
printTopNames
Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer.
You do not have to worry about an integer value large than 5 for the boy/girl names.
This method should open the file and parse the file and print the names as shown below:
Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas. For this file, set…

Save these files to your directory and study the code in both, then compile and run Factorials to see how it works. Try several positive integers, then try a negative number. You should find that it works for small positive integers (values < 17), but that it returns a large negative value for larger integers and that it always returns 1 for negative integers.Returning 1 as the factorial of any negative integer is not correct—mathematically, the factorial function is not defined for negative integers. To correct this, you could modify your factorial method to check if the argument is negative, but then what? The method must return a value, and even if it prints an error message, whatever value is returned could be misconstrued. Instead it should throw an exception indicating that something went wrong so it…arrow_forward
