Problem I
1. Write a Java program that copies the contents of a text file (source file) to another
text file. The program must ask for a source file name as long as an invalid file
name (e.g., a name for a file that does not exist) is provided.
2. Write a Java program that reads a sequence of integer values and computes the
average. The program will give the user the choice of reading data either from the
standard input (System.in) or from a file. In addition, the program will give the
user the choice of sending the output to the standard output (System.out) or a
specific file.
3. Implement a method named compareStrArrays that has the following prototype:
public static boolean compareStrArrays(String[][] array1, String[][] array2);
The method will return true if the arrays have the same dimensions and the same
String values. Keep in mind that each array can have rows with different lengths.
