in Java

2 - Write a program that asks the user to input an integer. Reads input inside a loop and check the input, if it is a integer print it out and quit. If it is not integer data re-ask the user to input an integer.

3 - Modify program 2 so that it checks the input - if the string the user entered is 'wombat' have your program print out that they guessed the secret word and are a winner! (for a challenge have it search for a sub string inside the string input)

4 - Write a program that asks the user for a float value. Write a static method the will square that value and return the results. The main will use that method on the input and print out the result.

5 - make a 1-dimentional array and fill it with 10 random integers between 0 and 100. Print out the contents of the array.

6 - Rewrite the array program so that it calls a method to generate the loaded array. It then calls a separate method to print the array.
